Description
Summary:The use of the mass structuring flowchart will make it possible to forecast the methane release when mining a coal seam, to determine in advance and reasonably areas of increased rock pressure on a coal seam and a powered support. It will allow forecasting the areas of the negative rock pressure effect along the length of a face, increasing coal mining performance due to a more accurate calculation of the load on a stope and the cutting machinery output, correcting the force of the working bodies of cutting machines when destructing a coal seam, selecting face supports according to their bearing capacity, planning measures to eliminate the negative rock pressure effect in these areas, strengthen a selvedge to reduce the visible coal sloughing. Coal mining performance and safety will increase.
