Temporal and spatial evolution mechanism of large-diameter borehole pressurerelief and permeable gas seepage in high gas coal seam
Mine gas extraction has the dilemma of low extraction rate, short effective extraction cycle, and substandard gas pre-extraction concentration. In order to realize the precise pressure relief and permeability of high gas and low gas permeability coal seam, taking the working face of high gas and low...
