The paper contains main aspects of methodological approach to objective analytic assessment of maximum permissible output of the mine faces from the viewpoint of gas factor. Analytic forecast is centered around the assessment of methane inflow into the face area from all possible sources, based on fundamental physical laws, modern tools of mathematical modeling and in-situ tests of main properties and state parameters of the gas-bearing coal formation. Objective and reliable estimation of permissible outputs is a starting point for justified selection of a seam degassing technology, that has to be based on time factor and predicted value of gas recovery from a coal seam to a degassing well. Recommendations have been formulated on the selection of degassing technology for the coal seam «Boldyrevsky» of the Kirov mine, based on the use of cutting-edge technological schemes (hydraulic fracture, carried out from development workings, etc.), successfully implemented on the mentioned site.
Problems are generalized for the purpose of providing safety in coal deposits mining at the Kuzbass. It was shown that the basis for providing safety should be a complex of safety measures in corporating a repeat geodynamic zooming of the overall Kuzbass, individual deposits and mine fields, multiphase degassing at all stages of mining , and also the gaseous, seismic, hydrogeomechanical and electromagnetic monitoring at productive mines. It was suggested to work out safety regulations for providing safety during intensive coal mining not for each individual holding, but for the whole Kuzbass.
The article deals with the aspects concerning the influence of geomechanical processes in rock mass on the selection of parameters of technological schemes for flat coal seams mining. Based on the analysis of experience gained under similar conditions at coal mines of the advanced national and foreign countries, the promising trends in the research work and development projects for the SUEK-Kuzbass Co.were suggested.
