Abstract For the problem of Dongpo Mine to Liujiakou Coal Preparation Plant conveyor coal transportation system crossing the below of Pingshuo Mine opencast special railway in K12 + 965, the method of numerical simulation was adopted, the deformation conditions of the belt corridor under the initial support were simulated. Calculation results showed that the underground corridor construction through railway sidings had little impact on railway and the surface deformation, completely in the range of specification, the analysis results had important guiding significance on engineering design and construction.
