To the determination of the economic efficiency of ore mining technologies

The article describes a method of comparative economic evaluation of technologies or options for the development of mineral deposits by underground mining, which, according to the mining and geological conditions, under these conditions may be alternative. It is shown that in modern conditions of changing technological structures, the hardening of the real economy involves the development of methods for evaluating the effectiveness of industrial technologies on a competitive basis. Definitions of terms and concepts in mining practice are given. As a criterion for evaluating the economic efficiency of the compared development systems, traditionally accepted is the magnitude of the conditional profit from mining and processing of ores in all areas of mining. The concepts of conditionally variable reduced costs are clarified. An algorithm for calculating the conditional profit for the technologies used for the extraction and processing of ores and the determination of them economically optimal is given...
