Research on Deformation Mechanism and Support of Mining Roadways in Residual Coal Remining
Based on the actual situation of residual coal re mining in the No.3 coal seam of Baigou Coal Mine,theoretical analysis and numerical simulation were carried out on the deformation and failure of the surrounding rock of the roadway.The deformation and failure mechanism of the fractured roadway surrounding rock was analyzed from the perspective of rock and soil damage mechanics.By adopting the support method of"grouting+anchor(cable)net",the deformation of the surrounding rock of the fractured mining roadway during residual coal re mining was effectively controlled.
