The goal of coal extraction in any section of a deposit is the realization of maximum possible profit. It is advised to determine profit using the proposed model including seven most important factors. These factors are coal production per an extraction block, recovery factor in ROM coal dressing, coal loss and dilution, final product price, aggregate cost and mine performance reliability. In order of influence on profit margin, the first place belongs to the factor of price, and then goes cost, dilution, loss and serviceability of a mining system. The mechanism of influence of each of the seven factors on the profit margin of a coal mine is analyzed. It is shown that the developed analytical model is a sufficient informative tool for the expressestimation of influence exerted by each factor on the final result (profit) of the mine performance and for the next ranking of technological and organizational measures in order of their significance. All this allows operation modeling and decision-making on different problems connected with coal mining.
