| Abstract: | Based on the engineering background that the roof lithology of roadway in the No.15 coal seam of Yixin Coal Industry is hard limestone,the original support scheme is optimized and designed by means of ground stress test,field investigation,original support scheme analysis and numerical simulation.The results show that the optimized supporting scheme has a significant effect on the control of roadway surrounding rock and reduces the economic cost of supporting materials. |
