DIGITAL MODEL OF A COALMINE FACE

The article presents the structure and implementation of a digital model simulating a face of a coalmine. The digital model takes into consideration the parameters of a mining seam, technical parameters of the mining machines used, and economic indicators. The model can be used to support decision-making on increasing the productivity of the longwall of a coalmine, assessing the effect produced by using of the new equipment or new technology. We gave an example of its use to determine the dependence of economic indicators of longwall operation on the length of the face and flow scheme of shearer operation.
