Optimal Simulation for Cable Anchor and Beam Coupling Support in Soft Compound Roof Coal Seam

In order to solve the problems of surrounding rock deformation and high failure rates caused by steel arch in soft compound roof coal seam in Wangcun Coal Mine, taking 5210 face orbit railway as engineering geological background, we used UDEC numerical analysis software to compare top, floor and two rock displacement vector field and plastic collapse field under different roadway conditions to determine the optimal support design scheme and carry out optimization for mesh beam anchor coupling support program implementation and monitoring in the field, in fact, test data and simulation results are coincidence, which verified the feasibility and rationality of simulation methods in solving practical problems.
