Abstract
The article deals with the problematic issues and features of further development of iron ore deposits at great depths (over 400 m). The necessity of wide application of innovative competitive technologies for ore mining by open method and an increase in the efficiency of mineral processing in the conditions of modern trends of sustainable development is substantiated. To solve this problem, a systematic approach is applied based on the consideration of all technological processes, taking into account the impact of mining operations on the environment as a single organizational and technological complex. It is proposed to use the Neumann-Gale model as an economic and mathematical model for assessing the investment activity of mining enterprises, which takes into account the influence of the environmental factor on the efficiency of their functioning. Approbation of the model was performed at the PJSC “Southern Mining Factory” as an example of production and economic activity. The priority measures are presented for the implementation of ecologically balanced strategies in terms of environmental protection for sustainable development at modern mining enterprises in difficult economic conditions and uncertainty of price characteristics in the markets of iron ore raw materials.
Highlights
When solving the problem of increasing the economic potential of Ukraine, a significant role is given to mining enterprises with an open method of developing deposits, which produce 85 % of the volume of commercial iron ore
The domestic iron ore base has certain features: first, it is the low quality of ores with a high content of harmful impurities; secondly, the depth of the quarries reaches more than 400 m and the conditions for the development of deposits are complicated, and most importantly, a small percentage of the use of innovative technologies for the extraction and processing of minerals, which causes a high energy, capital and material intensity, a negative impact on the environment
– making informed management decisions and measures based on the calculation of economic indicators as key factors for the successful socio-economic development of mining enterprises with the determination of the feasibility of technological changes in production for certain situations in the market of iron ore
Summary
When solving the problem of increasing the economic potential of Ukraine, a significant role is given to mining enterprises with an open method of developing deposits, which produce 85 % of the volume of commercial iron ore. The beginning of the study of technological processes of open development of mineral deposits, taking into account the economic feasibility of material and energy intensity of mining production, falls on the middle of the twentieth century. Despite the fact that in this direction thorough theoretical and practical work is carried out, including at the state level [19], in relation to the iron ore quarries of Kryvbas, comprehensive system studies in the context of improving the final results of mining enterprises on the basis of ecological, economic and energy efficiency assessment of mining and processing of minerals, taking into account modern trends in the global economy, have not been carried out recently, which undoubtedly indicates their relevance
