Essay

The dissertation is devoted to problems of efficiency increase of underlying coal layers decontamination. There were defined the layer degasification parameters to be supplementary worked. It was done in dependence with mining conditions. There was developed the method of expedient ventilation mode paying attention to the taking-out part degasification to get maximum breakage face loading. Mathematical model of gas pipe diameter optimization according to economic indices for separate parts of degasification network has been designed. It was done simultaneously for each part of the pipeline included into complex degasification network or in any direction under certain and expected approaches. The method of calculation and borehole quantity optimization and distance between them under the degasification mode of quasistationary perform and maximum, methane volume to be captured at the taking-out part has been improved
