Acid Mine Drainage Neutralization by Ultrabasic Rocks: A Chromite Mining Tailings Evaluation Case Study

Chromite is formed in nature in ophiolitic layers and ultrabasic rocks through fractional crystallization. The corresponding mining technologies separate the ore from these ultrabasic rocks, which are considered to be tailings for the process but may be valorized in other applications. The need to utilize this material is due to the large quantities of its production and the special management required to avoid possible secondary pollution. In the present work, the ultrabasic rocks of chromite mining were applied to acid mine drainage (AMD) neutralization. The aim was to increase the technological maturity of the method and promote circular economy principles and sustainability in the mining sector. Ultrabasic rocks were obtained from a chromite mining facility as reference material. Furthermore, an artificial AMD solution was synthesized and applied, aiming to simulate field conditions. According to the results, the sample was successfully utilized in AMD neutralization (pH 7), achieving rapid rates in the first 30 min and maximum efficiency (liquid to solid ratio equal to 8.3) at 24 h. However, the method presented a drawback since Mg was leached, even though the concentration of other typical metals contained in an AMD solution decreased.

Comparison and regional suitability evaluation of different backfill source heat pumps using TRNSYS

As global energy demand and carbon emissions continues to rise year by year, the use of renewable energy for heating becomes increasingly urgent. This study employs solar and geothermal energy to supply heat to mining facilities. Initially, three distinct heating systems for mining areas were modeled in TRNSYS: the Backfill Source Heat Pump (BSHP), the Solar Assisted Backfill Source Heat Pump (SABSHP), and the Solar Assisted Backfill Source Heat Pump with Seasonal Heat Storage (SABSHP-SHS). Following a decade of simulation, the optimal system was identified through a comparative analysis that encompassed backfill temperature equilibrium, the inlet and outlet water temperatures for buried pipes, Coefficient of Performance (COP), Partial Load Ratio (PLR), and economic factors. Over the 10-year simulation period, the COP and PLR of the SABSHP-SHS system outperformed both the BSHP and SABSHP systems, showing higher energy efficiency and better heat pump performance. To further assess the regional adaptability of the SABSHP-SHS system, simulations were conducted across four regions with diverse climatic profiles: Shijiazhuang, Yan’an, Xining, and Hegang. The analysis focused on heat collection, efficiency, backfill temperature variation, system energy consumption, and the energy efficiency ratio. The findings indicate that Hegang exhibits the highest solar heat collection efficiency at 89.9% during the non-heating season, while Xining achieves a significantly higher heat collection efficiency of 54.1% during the heating season. These results suggest that the SABSHP-SHS system is particularly effective in regions with pronounced seasonal variations, characterized by extended cold winters and brief, intense summers.

Assessment of aerosol radioactivity in the atmospheric air of populated areas

Introduction. Due to the tense situation in the world, which may lead to deliberate emergencies at radiation-hazardous facilities as a result of terrorist or sabotage actions, the availability of methods for operational control of radioactive aerosols in the atmospheric air, as well as knowledge of background levels of α- and β-activity of aerosols in the locations of nuclear power facilities, mining and processing facilities The aim of the study was to assess the radioactivity of aerosols in the atmospheric air according to the indices of α- and β-activity (using the example of the cities of Voronezh, Novovoronezh, Pavlovsk, Lipetsk, Stary Oskol). Materials and methods. Atmospheric air sampling was carried out using a flow meter-sampler of PU-5 aerosol mixtures. The α- and β-activity of the surface of the AFA-RSP-20 filters was measured with the MKS-AT1117M dosimeter-radiometer with interchangeable detection units BDPA-01 and BDPB-01. Results. The results of measurements of aerosols α- and β-activity in the atmospheric air in all control points in the territories of populated places established the α-activity of the aerosols to vary from 1.10 • 10–3 to 6.75 • 10–3 Bq/m3, total (total) β-activity – from 3. 49 • 10–3 to 2.12 • 10–2 Bq/m3. The maximum indices values took place at control points near the open-pit mining of the Shkurlatovsky granite deposit (near Pavlovsk, Voronezh region). Limitations. The limitations of the study are related to possible errors of the proposed and tested methodology, single (one-time) measurements, variable meteorological conditions affecting a specific result. Conclusion. The maximum values of aerosols α- and β-activity in the atmospheric air of populated areas are determined by the results of one-time measurements (6.75 • 10–3 Bq/m3 and 2.12 • 10–2 Bq/m3) do not cause concerns for the health of the living population.

Experimental assessment of strength characteristics of anthropogenic soils in a given mining area for justification of tractor propulsion type

BACKGROUND: In mining, there is a need to develop tractors as special robotic vehicles of the robotic mining facility that can efficiently move and work on soils with low bearing capacity, in waterlogged areas and in the underwater position. A preliminary evaluation of the strength characteristics of such a heterogeneous surface of the exploitation area helps to choose an effective concept and technical characteristics of the propulsor of the tractor. AIM: Formation of the database of the physical condition and mechanical properties of the environment in which the tractor will move and operate. METHODS: In order to achieve the aim, preliminary experiments were conducted on the terrain. Typical kinds of soil sites and watered areas, including those of anthropogenic origin, of a given mining area were identified. Full-scale instrumental tests were conducted to determine: granulometric composition of soils; physical and mechanical parameters of these soils at the selected sites using the developed original types of a penetrometer and a shear rig. RESULTS: The database of numerical values of measured strength characteristics of one of the soil types (as an example) as a possible supporting surface for vehicle motion in the area of mining facility operation is presented in a graphical form. The basis of this database is the graphs according to the results of experiments on free settlement and shear with the help of dies of two types of configuration (the round die and the original caterpillar track respectively); the granulometric composition of the selected soils has been evaluated. CONCLUSION: The methodology of preliminary assessment of the soil condition by two indicators of soil strength (the rut depth z depending on the average pressure under the die) and shear (average tangential stresses τ in the contact patch on the motion of the die relative to the soil, depending on the ratio of the normal force and the traction force in the contact plane) has been developed. The 3D model of the coastal and bottom area of the technogenic mining zone has been developed. Design variants of highly efficient types of tractor propulsors are selected on the basis of prediction of maximum allowable stresses in the contact patch with the ground for the bearing surface areas of the considered area of operation.

CSP+MED Plant Coupled to a Seawater Pipeline from the Mining Industry in Northern Chile: A Case Study

The study evaluated the use of mining seawater pipelines in a CSP+MED plant at commercial scale based on solar tower molten salts technology, with 111.2 MWe and 13 hours of thermal energy storage in northern Chile. The plant is coupled to the biggest seawater pipeline in the country, from Centinela mining facility. Results shown that the CSP+MED plant required all the seawater pumping capacity of the pipeline in order to cool the thermal cycle of the CSP plant using the MED plant. In terms of electricity production, the MED plant integration affects significantly the annual electricity production of the plant, when compared with an optimized CSP plant and to a CSP plant with the same design but without the MED plant and considering a once through cooling system, lowering the electricity production an 46.05% and 25.82% respectively. On the other hand, the CSP+MED plant integration produces 14.06 hm3 of freshwater annually, which translated in an additional income equivalent to 28.14 MM USD each year, which is substracted from the OPEX costs of the plant for the LCoE calculations. For this reason, the results showed that the lowest LCoE is reached by the CSP+MED plant configuration, but is highlighted that the economic analysis assumed an ideal situation, and further business models must be studied in order to share the benefits of the seawater pipeline integration between the CSP+MED plant owner and the mining facility that owns the seawater pipeline.

Deciphering climate change impacts on resource extraction supply chain: a systematic review

AbstractMining is becoming increasingly vulnerable to the effects of climate change (CC). The vulnerability stems from changing weather patterns, leading to extreme weather events that can cause damage to equipment, infrastructure, and mining facilities and disrupt operations. The new demand from governments and international agreements has placed additional pressure on mining industries to update their policies in order to reduce greenhouse gas emissions and adapt to CC. This includes implementing carbon pricing systems, utilizing renewable energy, and focusing on sustainable development. Most mining and exploration industries prioritize reducing mining’s impact on climate change rather than adapting to extreme weather events. Therefore, it is important to study and investigate the impacts of climate change on the mining sector. This paper aims to investigate the challenges and strategies for adapting to and mitigating the impacts of climate change on mining through a systematic literature review. The results indicate that the majority of proposed models and strategies in the mining field are still in the conceptual phase, with fewer practical implementations. It has been identified that there is a requirement for long-term planning, improved risk management plans, and increased awareness and education within the industry. Practical strategies such as integrating renewable energy, enhancing operational safety, and improving water and tailings management have been recognized as crucial for effective climate change adaptation and mitigation.

Evaluation of the possibility of searching for groundwater using electrical resistivity tomography based on the data of numerical modelling in complicated permafrost conditions (the case of the territory in the eastern part of the Republic of Buryatia)

Relevance. Groundwater is the main source of industrial and technical water supply for mining facilities. The geological structure of the studied areas can be complicated by various factors that make it difficult to search for and localize groundwater. In this regard, electrical geophysical prospecting methods are often included in the complex of prospecting and exploration works, before which it is necessary to justify the application of the chosen method for solving the problems by performing numerical modelling. Aim. To substantiate the use of electrical resistivity tomography for the search for groundwater, taking into account complicating factors, including perennially frozen rocks, taliks, and fault zone, by numerical modelling. Objects. Geological environment represented by Quaternary system rocks and permafrost rocks of Cretaceous sediments of the Zazinskaya intermontane area, fault zone, talik zones. Methods. Solution of the direct problem, solution of the inverse problem, ground geophysical surveys using electrical resistivity tomography. Results. Based on the performed numerical modelling, it is shown that the use of electrical resistivity tomography is expedient when searching for groundwater in the area characterized by various factors: permafrost, talik, and a fault zone. Based on the results of solving direct and inverse problems of electrical survey, using field works performed in 2020 in the Eravninsky district of the Republic of Buryatia as an example, it is shown that pole-dipole arrays in electric resistivity survey with electrode distance of 5 m, successfully confirmed by drilling operations, allow us reliably delineate potential zones of water inflow. These zones, characterized by low values of electrical resistivity, in this area, are related to talik zones, which are powered by heat flow from the bowels of the earth.

Noise considerations for the distributed modular-based approach to cryptocurrency data centers

While the establishment of cryptocurrency data centers becomes increasingly prevalent, the significant noise impact of these facilities on the surrounding community and environment has also become of interest. One of the most common designs for cryptocurrency mining facilities is to utilize a set of modular data centers, commonly constructed out of modified shipping containers, which are distributed over a large space. Each individual data center module can contain a large number of cryptocurrency mining computers, with each of these equipped with its own cooling fan system. The individual miner fans, coupled with the large ventilation fans required to cool the data center modules themselves, can lead to a complex, widespread acoustic environment that can be difficult to mitigate. This work presents commonly implemented noise mitigation strategies for cryptocurrency mining operations and the common issues that come along with those strategies, as well as operational limitations that must be considered when designing the proper noise control solution. Applications to regulatory constraints on noise, or lack thereof, are discussed.

MECHANISED COAL EXPLOITATION IN THE "BREZJE" PIT OF THE "DJURDJEVIK" BROWN COAL MINE

In addition to the coal and electricity market and changing geopolitical circumstances, there are other sufficiently rational reasons for opening new underground mining facilities and modernizing existing mining methods.Significant limiting factors and influences, in complex mining-geological conditions, most significantly affect the possibilities of the mechanized way of mining brown coal. The "Brezje" pit is a part of the deposit where the mining-geological factors are complex and determined by the natural conditions of the deposit's genesis. Excavation methods and technologies in complex deposit conditions must be based on great flexibility and adaptability.The complexity of the tectonic structure in the "Đurđevik" pit justified the application of chamber excavation methods with borehole blasting, in various technical modifications and solutions. In all previous solutions, the degree of mechanization of the method was not significantly improved and all modifications of the chamber method were non-mechanized or semi- mechanized with a large participation of manual work, technology based on drilling and blasting, high risk of injuries, low utilization of deposits, unjustified economic effects of work. The aim of this paper is to give an adequate answer to the hypothesis "in the block structure of the deposit with pronounced tectonics, it is possible to reduce the unfavorable influence of the complex mining-geological factors of the deposit on the excavation method by choosing modern mechanization for underground exploitation". The mechanized chamber method of excavation is a conceptual solution for the possible application in complex conditions of the proposed flexible mechanization for work in the "Brezje" pit. The advantage of modern multifunctional mining machines is a high degree of adaptability to the elements of the coal layer with the use of different working mechanisms (tools) that can be changed in a very short time depending on the working phase of the process. Key words: Pit, complexity, factors, chamber method, flexible, multifunctional machine

Определение стоимости обслуживания опасного производственного объекта профессиональными аварийно-спасательными формированиями

The existing methodologies to determine the costs of service for a hazardous production facility provided by emergency and rescue units have been analyzed. The issues hampering the calculations were identified, and the criteria to be incorporated into the calculation procedure, considering the identified shortcomings, have been proposed. Throughout the study, the following problems were resolved: The analysis of accidents at hazardous production facilities, federal laws in the sphere of industrial safety, and the existing methodologies to determine the cost of service for a hazardous production facility provided by emergency and rescue services or units; Identification of issues hampering the calculations; Proposing criteria incorporated into the procedure of calculation of costs of service for a hazardous production facility provided by emergency and rescue services or units. The authors refer to the statistics on emergencies at hazardous production facilities and focus on the fact that similar accidents cause devastating consequences requiring emergency and rescue operations. When operating a hazardous production facility, its operating company is required to enter into servicing agreements with professional emergency and rescue services or professional emergency and rescue units. Maintaining a servicing agreement with professional services is more cost-efficient compared with maintaining an in-house emergency and rescue unit. At the same time, the issue of determining a justified cost of the agreement with professional emergency and rescue services (units) for servicing a hazardous production facility becomes crucial. The article analyzes the Rules of calculation of costs of service for mining facilities provided by professional emergency and rescue services (units) and the Norms of minimum equipping of emergency and rescue units. The procedure of calculation of expenses on maintenance of personnel of professional services and the respective operational costs have been analyzed. It has been demonstrated that the calculated service cost is significantly higher than the service costs specified for tenders. The criteria incorporated into the cost calculation procedure for servicing a hazardous production facility by emergency and rescue services or units have been developed.

Risk assessment of cigarette butts and microplastic pollution in a drinking and irrigation water basin of West Anatolia, Türkiye.

Cigarette butts (CBs) and Microplastics (MPs) have serious harmful effects on the environment and living organisms despite their small size. This research aims to investigate the abundance and pollution status of CBs and MPs in Tahtalı Dam Basin (West Anatolia, Türkiye) which is the most important drinking and irrigation water resources. Clean Environment Index (CEI) and Cigarette Butt Pollution Index (CBPI) were used to determine pollution degree of the basin. The total number of CBs were 1.478 items, the total number of MPs were 477 items/m2 in the basin. As a result of this study, MP particles weren't found in Balaban Stream. Highest number of MP particles observed in 100-250μm (45%) size class. The most abundant MP type and colour were, fragment (54%) and white (42%), respectively. Polyethylene terephthalate (50%) was the most abundant type of polymer according to the ATR- FTIR analysis. As a result of the CEI and CBPI, the upstream stations of the stream were classified as "clean" status, while downstream sampling points of the stream and Balaban Lake coasts were classified as "extremely dirty" status. The calculated volumes of MP particulates from mining facility, agricultural and recreational activities indicate that anthropogenic factors are the most important MP source in the Tahtalı Dam Basin. This study is the first study about MP and CB pollution of the freshwater ecosystems in the region.

Terrestrial laser scanning in the construction of a numerical model geometry related to underground post-mining facility

Abstract The procedure of building a quasi-3D geometry of a numerical model of an underground post-mining facility is presented in the article. For this purpose, measurements were made, based on the terrestrial laser scanning (TLS) technology, of a fragment of St. John adit, which is part of the underground tourist route “Geopark” St. Johannes Mine in Krobica in Lower Silesia in Poland, in the neighborhood of Krobica, Gierczyn and Przecznica – the places located in the vicinity of the well-known health resort Świeradów Zdrój. TLS, as one of the most advanced mining surveying technologies, enables accurate mapping of even the most complex geometries of underground mining facilities. This opens wide possibilities in the construction of more accurate numerical models of the behavior of the rock mass around such underground objects. As a result, more reliable calculation results are obtained, which are the basis for designing mining support protection, for example, with rock bolting. This translates into an improvement in the safety of underground excavations, in the conditions of exploitation in mining as well as in historical post-mining excavations made available to tourists. In the construction of the geometry of numerical model, software such as Trimble RealWorks was used to orientate individual “point clouds” from measurement stations. CloudCompare software was also used to generate cross sections to the adit axis, and AutoCad software was used for processing and spatial orientation of a selected characteristic cross section. Using the latest version of the FLAC 3D v.9.0 software, the excavation cross-section geometry obtained from measurements was mapped to and discretized (i.e., meshed), giving it a third dimension at the same time.

Analysis productivity of the mine facility department using the objective matrix method (OMAX): case study in coal mining company

PT Kideco Jaya Agung is one of the coal mining companies in Paser Regency, East Kalimantan, using an open pit mining system which at the end of 2012 succeeded in realizing the production, transportation, shipping target of 34 million tons. Coal mining is carried out using excavating equipment and hauling equipment. Activities begin with land clearing using bulldozers and / or small excavators, blasting overburden and / or removal of overburden, cleaning coal, loading and transporting coal to the ROM Stockpile. Throughout 2021 there has been a decrease in production results, it is necessary to analyze the productivity of the company's performance, which in this case leads to the Mine Facility department because it is directly related to production. The need to analyze productivity measurements so that it can be seen whether the Mine Facility department in this company is productive or not. The productivity measurement method that can be used to solve the problem is Objective Matrix (OMAX), because the OMAX productivity measurement model overcomes the problems of complexity and difficulty of productivity measurement by combining all important productivity criteria into an integrated form and interrelated with each other and easy to combine.

Simulation modelling of residual resource for hoisting mechanisms in the mining industry

The rationale for prolonging the operational life of the crane is rooted in the economic viability of conserving metal and energy, leading to ecological benefits. Cranes, being structures with a high metal content, contribute to pollution reduction by eliminating the necessity for additional manufacturing processes in mining, metallurgical, machinery plants, and energy supply facilities. To assess the remaining service life, statistical simulation modelling is employed. The objective is to showcase the feasibility of determining the residual resource within the time interval using the Monte Carlo method in simulation modelling. In this analysis, multiple random parameter values are generated, and calculations are performed to form a statistical distribution of the results. The reliability theory utilizes the Weibull distribution. Once the distribution parameters are established, the residual resource of the metal structure operating in the interval can be ascertained. A crane with a service life of more than twenty years is considered, and the quantity is modelled randomly within the range from zero to one. From twenty experiments, the results indicate an average resource with a confidence interval of few years.

Observations and computational multi‐phase modelling in tropical river settings show complex channel changes downstream from rainfall‐triggered landslides

AbstractAlluvial river channels respond to changes in sediment supply by adjusting their geometry. Landslide sediment delivery and geomorphic response of river channels during floods are poorly understood and rarely examined in tropical settings. We investigate the impact of landslides on channel geomorphic changes during an extreme typhoon‐induced flood event in the Philippines, specifically the complex geomorphic response of the Antamok River to Typhoon Mangkhut in September 2018, which triggered >500 landslides in the Ambalanga catchment. The catchment has a legacy of anthropogenic modifications, such as extensive small‐scale (artisanal) mining and tailings storage facilities (TSFs) from large‐scale mining activities.We use a novel mix of mapping and computational modelling approaches to test the hypothesis that landslide sediment delivery is a major control on channel geomorphic change. Pre‐ and post‐event imagery show that the overall active channel area increased by 35.9% and the mean active channel width increased by 9.1 m. Spatially, we find no clear relationship between landslide sediment input or unit stream power and channel width geomorphic change, with longitudinal changes in active channel width complicated by TSFs. Multi‐phase modelling using r.avaflow revealed how landslide sediment delivery and TSFs interacted with the flow to generate the observed patterns of channel change. The model simulated channel incision in the upper parts of the catchment (up to 0.78 m) and deposition in the TSFs (up to 1.73 m).Our findings demonstrate that well‐established methods (e.g., stream power threshold) fail to fully explain channel width geomorphic changes, particularly for anthropogenically altered catchments. Integrating techniques, such as landslide mapping and multi‐phase computational modelling improves understanding of sediment supply's role in channel width change during extreme events. Numerical simulations also demonstrate that conventional assumptions of increased erosion and deposition with rising flow discharge are inaccurate with large sediment input, highlighting instead the effectiveness of multi‐phase models.

Determination of load-bearing capacity of piles used in stationary offshore platforms

Fastening of hydrotechnical oil-gas mining facilities to seabed soils in Caspian Sea aquatoriums is usually carried out by pile foundations. Sustainability of strength and stability during the design and construction of hydraulic structures requires to solve a number of theoretical and practical problems. Numerous static and dynamic tests (experiments) were carried out in the Caspian Sea aquatorium and in laboratory conditions to solve these issues. The widespread use of pile foundations in the development of offshore oil and gas fields revealed the inconsistency of the domestic scientific methodological and regulatory framework for calculating their load-bearing capacity over the soil. It is established that the wave strikes, acting on pile foundations, interact with the surface design of offshore structures and offshore ground bases. Sea wave banging pile foundations creates vibrations in the pile foundation - topsides offshore structures and moving piles in subgrade. Displacement piles depend on the strength of the reaction between the structure and subgrade, the intensity of the shock wave in the time that passed through piles for offshore soil. At the same time, it takes into account the rheological properties of composite models of shelf soil. Keywords: shelf; stress; ground; pile foundations; wave; marine structures; soil resistance.

RECONNAISSANCE SURVEY OF MOTHBALLED URANIUM MINING FACILITIES AND SETTLEMENTS IN THE SOUTHERN PART OF THE NORTH-KAZAKHSTAN REGION

This paper provides data of the reconnaissance (preliminary) radiation survey of mothballed uranium mining facilities (MUMF) and adjacent settlements in the southern part of the North-Kazakhstan region (NKR). It is shown that, according to the level of EDR values, MUMF locations, when the public periodically stays in these areas, do not pose any radiation hazard. The exception is Grachevskoe MUMF where EDR values reached up to 14.0 µSv/h. Around the settlements, EDR values vary from 0.1 to 0.5 µSv/h. Elevated values are noted on highways. Regulatory values of radon EEVA were also found to be significantly exceeded in Toksan bi vil. A minor excess of radon EEVA was detected in Novoukrainka vil. Exceedance of the content of 238U up to 4 MPC was detected in sources of drinking water supply. Exceedances of up to 5 MPC for 238U were also found in natural waters. The total alpha activity showed an excess of up to 15 MPC. Natural waters exhibit an excess of up to 10 MPC. Based upon the data analysis during the reconnaissance survey, the Grachevskoe MUMF and Novoukrainka settlement were selected for a detailed survey.

PLC BASED SCADA SYSTEM DESIGN FOR INSTANT MONITORING AND EARLY WARNING MECHANISM OF TOXIC GASES IN UNDERGROUND MINES

In this study, a real-time toxic gas measurement and early warning mechanism is proposed to prevent accidents that may occur in underground mining facilities. Temperature, oxygen (O2), hydrogen sulfide (H2S), methane (CH4), carbon monoxide (CO) and dust density sensor data are read via Arduino Mega analog inputs. All sensor data is transferred to the PLC-SCADA (Programmable Logic Controller - Supervisory Control and Data Acquisition) system via ethernet in real time. Thanks to the designed SCADA screen, sensor values can be monitored instantly. In addition, it can be checked whether the system is alarm and whether the ventilation system works. According to the underground coal mine regulations, work cannot be done in places where the mine air contains less than 19% oxygen, more than 2% methane, more than 50 ppm (0.005%) carbon monoxide and other hazardous gases. The highest permissible hydrogen sulfur ratio for 8 hours of operation is 20 ppm (0.002%). An early warning mechanism was created with the algorithm written taking these limits into consideration. The tests of the designed system were carried out in a laboratory environment and successful results were observed.

Изменение подхода к проектированию горнотехнических систем при открытой разработке месторождений на базе совершенствования принципов управления качеством горной массы

The main effect in transition of deep open pits to the In Pit Crushing and Conveying (IPCC) system of rock mass transportation is achieved through cutting the costs of rock mass hauling. Independence of the transportation system throughput from the haulage distance makes it possible to increase the boundary stripping ratio and extend the service life of the open pit. Transition from the cyclic to the In Pit Crushing and Conveying (IPCC) system of rock mass hauling still leaves insufficiently studied the issues related to assessment of the minimum commercial and cut-off grades of valuable components and contaminants in ores, the permissible thickness of the ore bodies when justifying the feasibility study of conditions, as well as management of the rock mass flow quality, optimization of the rock mass reduction ratio at the stage of its preparation for conveyor hauling from the open pit to the ore stockpiles and, further, to the ore hoppers of the processing plants, and many other challenges. The paper systematizes the results of other research by the authors as well as other data and it shows that the placing the crushing equipment and the belt conveyors within the boundaries of the open pit offers additional opportunities to manage the quality of rock mass flows, i.e. the ore mass and the overburden due to variations in the logistic and hauling schemes of the open pit due to transition to the In Pit Crushing and Conveying (IPCC) system. The above approaches to implementation of the rock mass haulage system in open pits remove the boundaries between mining and processing of minerals, expand the possibilities of targeted formation of technogenic deposits, and potentially expand the range of marketable products of the mining company. In fact, the mining and processing facility is considered as a unified technological process of the complete production cycle carried out in a single technological environment. Implementation of the proposed technological schemes will require changes in the regulatory and legal framework.
