Ecological and economic assessment of investment activities of mining enterprises

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.
