Abstract
For increasing the efficiency of longwall coal mining a mathematical model and a simulation model of the longwall coal mining were developed. 2D and 3D visualizations of the execution of the simulation model were realized. The main goal of the modeling of coal mining in a fully-mechanized stoping face is the comparison of flow charts of Longwall coal mining, the evaluation of performance of a drum shearer depending on such factors as technical parameters of the drum shearer, size of a stoping face, flow charts of the drum shearer operation, changing geomechanical characteristics of the coal seam. As a result of simulation the dependences of the drum shearer performance and annual mine profits on the length of the stoping face and flow charts of the drum shearer operation such as one-way flow chart, shuttle flow chart and bench flow chart were obtained.
