Presenting new technologies in underground coal extraction, with special attention to mine galleries support and maintenance, load mechanism of massif-support system-safety system systems, analysis of face equipment for thin coal seams mining and substantiation of rational stoping parameters. Advanced surface mining technologies of coal and ore are discussed in an original form, stability calculations of internal dumps and open-cut faces are presented, as well as examination of land surface subsidence using modern methods of calculation experiments. Special attention is given to the complex...
