Space–time modeling and process management in coal mining

Authors: Shulyatieva L.I.

The analysis of current and prospective situation in coal mining in Russia has found that index of face output buildup in longwall mines is lower than the index of coal consumption buildup in the domestic and international markets. Great depths of coal mining and high gas content of coal seams impede the efficient use of high-performance import equipment. Outputs per faces are much below a potential value. It is justified to concentrate mining operations both in time and space using such process flow charts that enable coal extraction from a number of longwalls simultaneously. It is necessary that production processes meet the technological parameters of such flow charts. In the author’s opinion, such modifications are the main internal reserve for performance stimulation in a mine, reduction of operating expenses and enhancement of efficiency of capital investment. This study justifies the necessity of mining scheduling based on improved production management. It is of the critical concern to account for the effect of deteriorating geological conditions on the process flow data, and to interlink the process flows in time and space. The model of the process flow design governing the mine performance during preparatory work, coal-face work, equipment installation and tear-down and gas drainage is described. The general form of the optimization model for subsystems is given.

Keywords: system approach, geological and geotechnical conditions, underground process flows, space–time representation, process and production management, step-by-step operation modeling, joint optimization of process parameters, planning optimization.
