Deformation and failure characteristics of gas drainage drilling-reaming coal mass in non-uniform stress field
The deformation and failure characteristics of coal around gas drainage boreholes in deep soft and low permeability coal seams affect coal seam gas pre-drainage. Based on the condition of non-uniform stress field, the mechanical model of borehole disturbed coal mass was developed, the analytical sol...
