Makarov V. Optimization of development of technological systems of coal mining by indicators of energy and economic efficiency

The mathematical model of optimization of mining technology, which unlike the balance-wide optimization models using economic criteria focused on improving production efficiency of selected sub sector the criterion of overall performance. The model is built to as mixed-integer programming, allowed to determine the optimal scope of the criterion set options for domestic production technical re lava pits, providing industry competitiveness in the global coal market. A new method of forming a plurality of promising options for technological re-equipment of mines, which allows comparing the integral quality criteria reasonably decide on the appropriate selection of equipment options lava pits highly productive extractive equipment that best meets geological conditions specific ranks at maximum efficiency and reliability of its operation. Unlike existing approaches to justify the choice of types of mining equipment, the proposed method uses the integral quality criteria are not only indicators of compliance geological conditions specific ranks, but the projected ash content of coal produced, indicators of energy and economic efficiency of its operation.
