Abstract
The article gives the analysis of basic mechanisms in variation of output of production heading versus its length in the cutter-loader and scrape conveyor system in underground mining of flat-lying coal beds. Based on the analysis of interaction between cutter-loader and scrape conveyor, the dependence between the maximum capacity of production heading and the longwall length is determined.
