Analysis of Optimisation Practice of Tunnel Support in Coal Mine Back to Mine
Taking 1031003 working face of No.10 coal seam in a coal mine as an example,a kind of optimisation scheme for back-mining roadway support is introduced,which includes three parts,namely,optimisation scheme for main and auxiliary transport runway,optimisation scheme for main withdrawing channel,and support scheme for cutting eye.In order to test the application value of the optimisation scheme,numerical simulation is used to compare the original scheme and the optimisation scheme,and after preliminary confirmation of the application value of the optimisation scheme,the optimisation scheme is applied in engineering practice,and it is finally confirmed that the optimisation scheme can meet the requirements of the roadway support of the working face.
