Numerical simulation on gas drainage and borehole arrangement parameters of bedding borehole in a coal mine
Based on comprehensive consideration of gas flow inertia and slippage effect, a gas drainage flow model was established. Based on engineering background of 12150 coal face of the No.15 coal seam in Songhe Coal Mine, the distribution law of gas pressure and the change of permeability under condition...
