An Asteroid Mining Model Based on Input and Output Equity

With the progress of science and technology and the rapid consumption of earth resources, the exploitation of outer space resources such as planetary mining has become an international hot issue. The power gap between countries in today’s world is so wide that how to realize the so-called fairness has become a problem worth thinking. Firstly, we establish an Input Output Equity Model (IOEM) to measure global equity. We define global equity as the balance between the input of human and material resources in the management and construction of a country and the overall strength of the country. Ten sets of data from many countries are divided into four categories: Science and technology, Traffic, Workforce and Energy consumption. We used the Entropy Weight method (EWM) based on TOPSIS comprehensive evaluation to determine the weight of each part and index, comprehensively evaluated 12 countries covering six continents and calculated their input equity index. Then we compared the index with the GDP of each country and found that the overall trend was consistent. This shows that there is a balance between input and output, which verifies the rationality of the model. We then establish the Asteroid Mining Model (AMM) to evaluate and predict the Asteroid Mining capabilities of various countries. In combination with the whole process of asteroid mining and the analysis of main components, we choose these three indicators: Scientific Research (SR), Exploitation of Mineral (EM) and Aeronautics and Astronautics (AA) to measure. We use the analytic hierarchy process (AHP) to determine the weights of the three factors and calculate Asteroid Mining Model (AMI) for each country. Then, the model is applied to two representative countries, China and Colombia, and the future is predicted by fitting. According to the results, it is concluded that the asteroid mining industry has a good development prospect. Next, we use correlation analysis to discuss the impact of the asteroid mining industry on global equity and conclude that there is a correlation between the decision index of asteroid mining and equity index, among which the correlation coefficient between aircraft and equity index reaches 0.9290. It can be concluded that the development of asteroid mining in the future will inevitably affect global equity. Furthermore, in order to explore how changes in asteroid mining will affect global equity in different ways, we carry out multiple linear regression analysis of variables from macro and micro perspectives respectively and find that the development of asteroid mining industry will indirectly affect global equity through its impact on computers and researchers. Finally, based on our findings, we propose policy recommendations for the development of asteroid mining to the United Nations from the perspective of global equity. Our advice can be summed up as “Inspire, Share and Collaborate”. We hope that while promoting scientific and technological development and exploration of outer space, all countries will enjoy friendly cooperation and common development so as to realize a fair and beautiful vision of the universe.

Measuring green development index and coupling coordination of mining industry: An empirical analysis based on panel data in China

Due to the quick adaptation of the mining industry and demand for the mining industry is growing due to the need for minerals and metals, green mining industry has earned much support. China has taken specific actions and made the advancement of green mining a crucial part of establishing an eco-society. Growth tactics utilized by traditional mining economies had negative repercussions, including resource depletion and deteriorating environmental conditions. For China, when formulating reasonable and scientific policies, a fair evaluation of the mining industry's level of green development has significant practical relevance. This study employed 16 common indicators divided into four categories: economical and intensive utilization, ecological environmental protection, scientific and technological innovation, safety and harmony, etc. The analytic hierarchy process (AHP) method and the entropy weight method (EWM) were used to reflect the relationship between indicators at different levels. In addition to the coupling of subsystems coordination model, which reveals the relationship between subsystems, scores of subindexes and weighted indicators are also derived. The empirical findings demonstrate that (1) despite non-cyclical fluctuations in the development of China's green mining industry, the overall index exhibits an upward trend from year to year; (2) the coordination of China's green mining industry subsystems is basically inconsistent, stage-wise balanced, and lacks precise coordination; and (3) the development of China's green mining industry is challenging, especially in the management and resto areas. Furthermore, the framework for green mining growth described in this study can be applied to other regions or sectors.

Numerical simulation research on bolt supports’ mechanical properties deformation in high-stress roadway

With the rapid development of domestic mining industry, it is necessary to consider the safety of the mine when mining. In order to improve the high stress environment and the frequent failure of bolts caused by the increase of excavation depth, in this experiment, FLAC3D is creatively proposed to establish the calculation model of bolt support roadway, analyze the basic geological environment and surrounding rock structure of the research area, and conduct the numerical simulation of the mechanical characteristics of bolt support deformation (BSD) in the high stress roadway (HSR). The basic geological environment and surrounding rock structure of the study area are analyzed, and FLAC3D is adopted for establishing a calculation model of the bolt-supported roadway, which can be used to simulate the axial and lateral forces of the bolt, and then determine the boundary conditions. It is found that the supporting bolt in the roadway needs to bear not only axial tension, but also transverse shear and bending. Based on the Winkler foundation beam principle, a calculation model of the bolt’s lateral bending force in the soft rock roadway is established, the lateral force characteristics of the bolt support are analyzed, the concept of “anchoring composite bearing body” is proposed, and the force characteristics of the bearing body are calculated. The research results show that in the HSR, the bolt mainly bears the combined forces of tensile and lateral bending; among them, the bolt’s axial force remains basically unchanged at the tail part near the pallet, and the bolt’s axial force at the end part deep into the rock mass decreases rapidly. The bending moment of the bolt is “wave-shaped” distributed along the length of the rod body in the positive direction and negative direction of the axis, and the comprehensive action of the axial tension and transverse bending of the bolt increases when the stress concentration increases. A smaller roadway radius will lead to longer bolts, denser arrangement and higher support strength.

Environmental taxation impact on the development of Ukrainian mining industry

The article reveals the main directions of influence of environmental taxation of enterprises in the mining industry. Using the correlation matrix, the relationship between resource taxation and financial indicators of their activity, as well as indicators of pollution and financing of protection by companies in the mining sector is determined. A complex of one-factor regression models was built to assess the impact of environmental taxes on the development of the mining industry. It is proposed to implement in Ukraine certain tax stimulating tools that are the most successful in the EU countries, so that environmental taxes stimulate investment and innovation activities in the field of environmental protection. The purpose of the article is to investigate the main areas of positive and negative impact of resource taxation on companies in the mining sector, as well as search for ways to improve environmental taxation, based on the experience of foreign countries. As a result of the conducted research by the methods of regression analysis, the impact of resource taxation on certain indicators of the mining activity in Ukraine was established. The obtained results indicate that the environmental tax is quite limited and has no potential to influence the analyzed indicators, instead, the rent fee has a good impact potential. Thus, the practical significance of the conducted research concerns to the development of recommendations regarding the mechanism of resource taxation the introduction of relevant tax incentive tools in Ukraine. These and many other measures will contribute to environmental taxes stimulating investment and innovation activities in the field of environmental protection. By the way, they are a means and a method for solving the problem of redistribution of funds in the direction of increasing the financing of programs aimed at rational use of nature and preservation of the quality of the natural environment.

Retrofitting Existing Urban Voids

As an abandoned mining area, Huanglong Mountain Purple Sand Mining Area in Dingshu Town, Yixing City, Jiangsu Province has entered a state of suspension of production. This study draws on successful cases and retrofits the abandoned mining area in Huanglong Mountain into a “source of purple sand” community park. With purple sand (the represent of the urban) as the core, museums are built to realize the restoration of the ruins and at the same time display the culture as well as history of the development of purple sand mining and pottery industry through photos and historical documents. This community park also provides ordinary pottery artists with opportunities to display their works and participate in cultural inheritance through workshop, narrating their learning experience to encourage youngsters. Some basic facilities like teahouses, restaurants, hotels and bazaars associated with local elements are created in the park to help tourists to experience the local pottery art life and boost economy prosperity of the city.

Junior Miner internationalisation in the globalising mining industry

Firm internationalisation is a key globalisation process. However, little is known about how ‘junior’ mining firms establish their operations overseas under industry-specific contexts. Here, we draw upon the economic geography and international business literatures to examine the case of Australian junior miners in the Latin American lithium and copper industries. Based on insights from 49 semi-structured interviews, findings show that the internationalisation of junior miners evolves through emergence, establishment, and maintenance stages in which the activities of firms, government and industry actors combine and are contingent upon external market conditions. As the objectives and internationalisation conditions of junior miners differ from those of larger firms, who expand seeking long-term establishment in developed markets, juniors' ephemeral timelines take divergent pathways. This study provides an alternative view on internationalisation, linking it to the emergence and growth of mining economic activities in regions with under-developed or developing market conditions. It also creates an understanding of the activities and external dynamics shaping junior internationalisation, informing investment attraction and regional development policy in mineral-rich nations where domestic capital for exploration is both scant and necessary for mining industry development.

Safety monitoring method of moving target in underground coal mine based on computer vision processing

Coal is one of the main energy sources in China. The country attaches great importance to the development of coal mining industry, and coal production is on the rise. At the same time, mine safety accidents are becoming more and more frequent, and the country is paying more and more attention to mine safety accidents. The underground environment of coal mine is complex, noisy and uneven, and there will be problems such as occlusion and high false detection rate during video monitoring. In order to ensure the safety of underground personnel, moving target detection and tracking based on video monitoring information is of great significance for coal mine safety production. The purpose of this paper is to study how to analyze and study the monitoring of moving targets in coal mines based on computer vision processing, and describe the image processing methods. This paper puts forward the problem of target monitoring, which is based on image processing, and then elaborates on the concept of image enhancement and related algorithms. From the average gradient, the algorithm in this paper is 56.60% higher than the histogram equalization algorithm, and 68.26% higher than the dark primary color prior dehazing algorithm. and designs and analyzes cases of image enhancement in coal mines. The experimental results show that the information entropy of the algorithm in this paper is 31.10% higher than that of the dark primary color prior dehazing algorithm, and 18.72% higher than that of the histogram equalization algorithm. It can be seen that the algorithm in this paper can achieve better enhancement effect.

At the same time, Blockchain technologies will increase the role of trade unions, which will be able to unite gig workers into a single system and control working conditions, taking on certain social obligations.

The Initiation Study on the Gold Potential Resources at West Coast Area in Lampung Province, Indonesia

Gold mineral (Au) is formed due to an increase in the residual solution of magma deposited at high temperature and pressure. This study aims to estimate the potential of gold minerals in the west coast area in Lampung Province. This initiation study was using a geophysical resistivity model. Based on geological data, gold minerals in the West Coast are classified as epithermal hydrothermal deposits in the form of low sulfide quartz veins. The results of the subsurface interpretation were identified as a gold mineralization zone associated with the rock in the form of volcanic rock which has a resistivity value of 400?.m. The source rock volume has been estimated at 130,000 m3 and ?133,000 m3. So that the Au mineral content in the study area is estimated at 0.5-2.09 tons. A future study should be conducted in relation to the development of gold mining industry in Lampung West Coast area, that may integrate more engineering experts.

Selected technology-critical elements as indicators of anthropogenic contamination of surface water and suspended solids on the example of the Biała Przemsza River (Poland)

Pollution of surface waters from anthropogenic activities is a global problem, affecting natural ecosystems, having a large impact on the life and health of living organisms. The development of mining and metallurgic industries of Pb and Zn ores in the Biała Przemsza cachment area has had a strong influence on the surface waters and suspended solids. This paper proposes the use of selected critical elements such as Tl, Te, Ga, Ge and In as indicators of anthropogenic pollution of surface waters and suspended solids on the example of the Biała Przemsza River. The impact of strongly anthropogenic urban-industrial catchment on the temporal and spatial distribution of the selected TCEs content in the water and suspension of the Biała Przemsza River depending on the oxygen, pH and Eh conditions is presented. Research has shown that selected critical elements such as Te, Ge, and In can be indicators of anthropogenic pollution of surface waters. In the case of the Biała Przemsza River, elements such as Ga and Tl cannot be indicators of anthropogenic pollution due to their presence in the zinc and lead ore deposits occurring in the river basin. Correlation matrices showed significant relationships between the selected TCEs and other water parameters. The calculated water pollution indices confirmed that the Biała Przemsza River is the most polluted in the last three sampling points.

Impact of FDI in Economic Value Added: Empirical Study in Terms of Renewable Natural Resources Mining within Wood-processing Industry

The traditional methods used in the past to assess the benefits of foreign direct investments (FDI) are no longer applicable. The presented study deals with the issue of increasing the potential of the renewable natural resources mining industries and increasing its efficiency and competitiveness through the specific methodology of industries performance measurement and diagnostic of the effects of FDI. The objective of the research was to analyse FDI in Slovakia and other countries of the Visegrad Four, identify significant measurable effects of the FDI impact on the development of the wood, paper and furniture sector in Slovakia as well as quantify the economic performance of given industries based on the EVA model. Appropriate mathematical and statistical methods were used in the research of interdependencies between quantitative variables. In two-dimensional inductive statistics, we applied correlation and linear regression analysis and analysis of variance (ANOVA). The results of the research should support investment decision-making in business and industry investment strategy to aim for the economic development of the renewable natural resources mining industries. Simultaneously, we offer a new methodology for evaluating the potential and economic performance of other Slovak mining industries, other post-communist European countries, and potential investors worldwide.

Dissolved trace element concentrations and fluxes in the Irrawaddy, Salween, Sittaung and Kaladan Rivers

The Irrawaddy (Ayeyarwaddy) and Salween (Thanlwin) globally rank among the largest rivers for supplying dissolved and particulate material to the ocean. Along with the Sittaung and Kaladan rivers they have societal importance to Myanmar in terms water sources and food production. Despite their importance for global biogeochemical cycles and the ~50 million people who live in their catchments, the chemistry of these rivers is poorly known. This study presents a comprehensive survey of dissolved (<0.22 μm) trace element concentrations (Sr, Fe, Al, Ba, Mn, V, Rb, Cu, Zn, As, Li, Ni, Mo, Cr, U, Pb, Sb, Co, Cs, Tl and Cd) at 38 locations within these river catchments, spanning a period of 2 years. The results highlight the global importance of the Irrawaddy and Salween rivers for trace element global biogeochemical cycles; contributing between 1 and 17 % of global dissolved riverine fluxes to the land-ocean interface for the studied elements. Area normalized dissolved fluxes in these catchments are ~2 to 10 times higher than global average values for most elements, consistent with high rates of chemical weathering. In general, anthropogenic activities have yet to significantly perturb dissolved trace element fluxes in these river systems. The presented dataset should therefore serve as a useful ‘natural’ baseline, against which future perturbations driven by climate change and/or the development of Myanmar's mining industry could be assessed. Exceptions to this include As in the Sittaung River and Sb, Zn, Pb and As in the Salween River, which may already be significantly impacted by anthropogenic inputs. The former represents a water quality issue of concern for public health, and so constraining the exact sources of As in the Sittaung River should be considered a priority for future research.

From the streets to the classroom: power analysis as a tool for critical pedagogy

ABSTRACT We focus on a power analysis exercise used with undergraduate students to discuss the environmental, economic, and social crises as they are reflected in the conflict between the economy and the environment, and local resistance to mining industry development in a region of Northern Greece (Chalkidiki). A power analysis exercise is a tool, designed and used by (community) activist groups to help understand the terrain of struggle and the actors involved. The exercise was also combined with, and followed from a reflection by the students on their ideological/political position on a spectrum from free market to deep ecology. The power analysis exercise helped students engage with the critical content of the module, understand how the different approaches/positions of sustainable development can manifest themselves, what their implications are, go beyond the academic lingo and reflect on how these issues impact our lives, rethink their positioning beyond the customer/manager dominant position.

Post-industrial shifts in the world’s mining industry

The changes in the sectoral and spatial structure of the world’s mining industry that occurred the period during 1980–2019 in the conditions of post-industrial development of the world economy are considered. The relevance of the study is dictated by the global process of dematerialisation of the economy under the influence of scientific and technological progress and the transition of world production to the principles of sustainable development, which causes not only a change in the role of the mining industry in the structure of the economy, but also entails a qualitative transformation of its spatial structure. On the base of calculations of indices characterising the intensity of dynamics, structural shifts and the spatial concentration of the volumes of mineral raw materials extraction with the subsequent interpretation of their values, the key trends in the development of the mining industry and the features characteristic of its constituent sectors, including the extraction of coal, oil, natural gas, iron ore, bauxite, copper, potash and phosphate rock were identified. The result of the conducted research is the revealed features of the mining industry development in the post-industrial period, which consist of positive dynamics of its functioning, stabilisation of the sectoral structure and strengthening of the positions of developing countries and individual regions in the extraction of mineral resources. The obtained results allow us to assess the features of processes taking place in the primary sector of the world economy at the present stage of development and the role of individual countries and regions in the mining industry of the world.

Metallogeny of Endogenous Gold in Tuva

Abstract —Analysis shows that the occurrences of ore gold of different mineragenic types and ages widespread in the Republic of Tyva are related to the intricate and long geologic history of this region. The Tyva region is of polycyclic development; in the period from the Precambrian to the Cenozoic, there were stages of subduction, accretion–collision, and rifting processes accompanied by volcanism of different types and a wide manifestation of granitoid magmatism. Gold metallogeny was discretely developed throughout the geologic history of the region and was most widely manifested at the island arc stage (570–510 Ma), in connection with the formation of gold-bearing pyrite–polymetallic deposits. The late Cambrian–Ordovician period of granitoid magmatism was also productive for gold mineralization: It was marked by the formation of porphyry Au–Cu–Mo and gold deposits and gold–skarn, gold–quartz, and gold–beresite ore occurrences. Several gold-bearing clusters confined to different structure-formational zones are distinguished in the Tuva area. By now, commercial gold contents have been established in the Tardan gold deposit with Au reserves of 7371.8 kg, in the gold-bearing Kyzyl-Tashtyg pyrite–polymetallic deposit with estimated gold reserves of 15.08 tons and silver reserves of ~700 tons, and in the gold-bearing Ak-Sug porphyry Cu–Mo deposit with C2 gold reserves of 83 tons and silver reserves of 368 tons. In the course of prospecting and revision performed at many gold ore clusters in recent years, additional information about the high endogenous-gold potential of the Republic of Tyva has been obtained. There are a number of objects promising for commercial reserves of endogenous gold, such as the Kara-Bel’dir gold ore cluster with C1 and C2 gold reserves of 22.8 tons, the Aldan–Maadyr gold ore cluster with predicted P2 gold resources of 38 tons and Р3 gold resources of 80 tons, the Eilig-Khem ore cluster with predicted P3 gold resources of 36 tons, the Kyzyk-Chadr ore cluster with predicted Р1 + Р2 gold resources of 39.7 tons and silver resources of 198 tons in the Kyzyk-Chadr deposit, and the East Tannu-Ola ore district with gold resources of 68.3 tons. Thus, the intricate geologic development of the Tyva area and various geologic events, including large-scale magmatic processes, led to the formation of both gold and gold-bearing deposits and ore occurrences, which give reason to anticipate revealing of large commercial reserves of endogenous gold and the development of gold mining industry in the republic.

Contribution of Mining Industry in Chosen EU Countries to the Sustainability Issues

In recent years, the mining industry has achieved an important position in the national economy due to its increasing productivity. However, since 2000, there have been signs of a slowdown, resulting from the national and local conditions of the mining industry. It is for these reasons that we have concluded that this type of industry must be assessed not only from the economic but also from the national and regional sectors, because the performance of the mining industry is directly affected by the value of mineral deposits and the structure of other industries. The present paper aims to analyze the development of the mining industry in Slovakia, in comparison with similar development in chosen European Union countries. Slovakia has been considered as a country with mineral resources and mineral-based products representing an important part of Slovakia’s foreign trade, with the significant imported mineral resources including mainly mineral fuels and ore raw materials. The development of the mining industry is assessed from the economics through the growth rate of gross domestic product (GDP) and through the national aspect through the rate of growth of the national economy. The aspects are evaluated by the multi-criteria method Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), with which we evaluated the country with the best mining industry development. The results of detailed quantitative analyses of the selected indicators for mining industry development for individual European Union countries show a fluctuating trend during the observed period, which is characterized by development disparities. Such results can be used to determine raw material policies in the relevant countries.

Mining Engineer L. F. Grauman and the gold mining industry development in Russia

Russia began to establish its gold-mining industry since the end of the 19th&mdash;beginning of the 20th centuries and quickly became the world&rsquo;s top gold producer. Gold mines of East Siberia made a foundation of the Russian gold industry and for a very short period developed from little handicraft diggings into big companies and transnational enterprises like Lena Gold Joint-stock Company. One of the key figures who played a significant role in launching and growth of the Russian gold industry was Leopold F. Grauman, a graduate of the Saint Petersburg Mining Institute. He was a type of a person who integrated the public interests in increasing gold production and the private initiative in development and foundation of the Russian gold industry as a rentable branch of industry based on long-term scientific planning and approach. Grauman was a kind of practitioner, who on his own experience knew how to organize geological expeditions in difficult to pass Siberian taiga, a year-round gold mining in difficult permafrost conditions, usage of technical innovation that indirectly influenced the development of domestic machine industry and production of machines for extreme weather conditions. He initiated the establishment of the Permanent Advisory Committee of gold and platinum entrepreneurs in order to transform Russian gold industry from spontaneous into a planned one. The Committee published its own journal and held regular congresses of gold and platinum entrepreneurs where delegates elected by the regional congresses represented the interests of the regions. The congresses were empowered to make decisions on technical improvements and funding of gold industry as well as questions of labor legislation and improvement of professional level of gold mine workers and employees.

Construction and Application of Relationship Model between Development of Mining Industry and Carbon Emission of Energy Consumption

With the world’s consensus on low‐carbon emission reduction, all walks of life have formulated low‐carbon development goals. As a high‐energy consumption industry, it is urgent for mining industry to implement the development strategy of low‐carbon emission reduction. Therefore, this study tries to provide reasonable suggestions and references for the low‐carbon development of the mining industry. Firstly, this study analyzes the industry development, energy consumption, and carbon emission of mining industry from 2000 to 2020. Then, using the Tapio theory, this study constructs the analysis model of decoupling between carbon emission of mining industry and industry growth. The analysis method of decoupling state assignment is proposed for the first time in the model. At the same time, the energy efficiency decoupling index and energy structure decoupling index are introduced to explain the causes of carbon emission decoupling. The research shows that the carbon emission of energy consumption in China’s mining industry peaked in 2013, and the energy efficiency decoupling in 2001–2014 is the main driver of carbon emission decoupling. The sharp growth of industrial output value leads to the decoupling of energy efficiency. At present, the improvement of energy efficiency of China’s mining industry faces great resistance. At the same time, the inhibition effect of energy efficiency on carbon emissions is limited, and the energy structure will be the main factor to inhibit carbon emissions.

Study on the Change of Eco-Environmental Quality in Jiufeng Mountain Area Based on InVEST Model

Habitat is not only an important place for animals and plants to inhabit and reproduce, but also the basis of human survival and development. With the large-scale development of mineral resources, land use types have changed sharply, fragile habitats tend to collapse, and the future sustainable development has lost a stable carrier. Habitat quality is a comprehensive expression of the interaction of many factors such as land, biology and water resources for many years. Natural factors are the most direct factors affecting habitat quality, and human activities are the most intense factors. The habitat module of invest model was used to evaluate the changes and temporal and spatial characteristics of habitat quality in Jiufeng Mountain from 1990 to 2018. It is found that the habitat quality in Jiufeng Mountain area shows a downward trend, and the ecological environment is very fragile. The high value areas of eco-environmental quality are mainly distributed in mountainous and hilly areas with high vegetation coverage; The low value areas of eco-environmental quality are mainly distributed in industrial and mining land and gully areas. With the development of society and economy and the development of mining industry in Jiufengshan area, the area of construction land is also increasing.

Research on Asteroid Mining Based on Entropy Weight Fair Index Evaluation System

The universe is rich in mineral resources. With the rapid development of commercial space flight, people gradually begin to consider the possibility of asteroid mining. In this paper, we have developed a set of measurement models to assess the level of capacity of countries. In this paper, we first select the original data of 13 indicators from 106 countries and use entropy method to determine the weight of these 13 indicators. On this basis, a global equity index evaluation system model based on TOPSIS is established to score the fairness of these countries. In view of the future development of asteroid mining industry, we analyze the possibility of asteroid mining in the future from three aspects: capital, technical capacity and mineral trade.
