Abstract: In order to solve the problems of deep excavation, low strength of surrounding rock, serious roadway deformation and high support cost of W2710 transport roadway in No.1 mine of Datong, on the basis of optimizing the roadway section, three kinds of roadway support schemes are proposed, and the numerical simulation method is used to compare and analyze the reliability of each scheme to obtain the optimized support scheme. Finally, the reliability of the optimized scheme is verified by field test. The field results show that:after the optimization of roadway support scheme of W2710, the maximum movement of roadway roof and floor is 67.22 mm, which is reduced by 51.33% compared with that before optimization; the maximum convergence of deformation on both sides of the roadway is 59.32 mm, which is reduced by 50.11% compared with that before optimization. In a word, the optimized support scheme can well limit the deformation of roadway, and the support cost can be significantly reduced.
