English abstract

The goal of the work is to develop and verify a new methodological approach for the comprehensive assessment of the technological potential of coal mining en- terprises. To address this task, a comprehensive approach has been applied, based on the implementation of the neoclassical production function in the form of the Solow model to analyze the state of the coal mining industry. It also involves evaluating the economic reliability coefficient to develop recommendations for improving techno- economic indicators. The efficiency of enterprise functioning can be assessed by the ratio of input (capital) to output (production level) flows of resources, with a significant role played by the innovative component. Analyzing the relationships between resource flows allows selecting optimal production development scenarios and forming prin- ciples for designing production at a certain stage of development. For the first time in the paper, a model for evaluating parameters of mining pro- duction is proposed, demonstrating the relationship between production functions and resources. Using the developed model, it is possible to track the efficiency of the use of production resources over time, determine production volumes, calculate the main parameters of coal mines' functioning, and investigate the resources contrib- uting to increased productivity. Regularities in the formation of the efficiency level of coal mining enterprises are established for the first time, and approaches to production design considering the area of rational exploitation are developed. Methods of combined management of processes of simple and extended repro- duction of technological schemes of mines are proposed by regulating the resource potential of mines. The procedure of gradient reduction of the limit on technological resources and adjusting the functional value to approach results in mine operation to a possible breakeven threshold is a widely recognized form of sensitivity analysis of modeling results. The comprehensive assessment of the technological scheme of the mine in four directions significantly increases the objectivity level of the final result compared to evaluating it with only one indicator.
