Permeability Enhancement of Coal Seam by Lower Protective Layer Mining for Gas Outburst Prevention
Risk prediction of dynamic disasters such as rock burst, gas outburst, and water inrush is closely related to the permeability evolution of coal seam. According to the characteristics of the lower protective layer mining, the basic assumption of gas-solid coupling model of the coal was proposed in t...
