Tóm tắt

This work aims at solving the problem of prevention and control of coal and gas outburst disasters that are dominated by stress in a deep coal seam. It is found that hydraulic slotting and gas extraction lead to double pressure relief for the coal seam stress and gas. A double pressure relief coefficient is proposed. Mechanical seepage experiments of horizontal fracture coal samples with different double pressure relief coefficients are designed (
