Abstract
Using inverse distance weighting (IDW), the model of a coal seam with distributed geological and geomechanical characteristics is developed. The hyperbolic dependences of the cutter-loader advance feed and capacity on the coal seam thickness are found. Influence of coal face spalling on cutter-loader capacity is assessed. Using the specialized library of MTSS, the integrated model of process flows in coal face area is developed. It is found that there exists cutter-loader capacity maximum at the increasing dependence of coal cuttability on longwall length.
