By analyzing and summarizing the observed data from the monitoring station of coal mining surface deformation under the electrified railroad at the 2914 working face of Dongpang Mine, the parameters of coal mining surface movement and deformation under the railroad were derived. Based on the comparison of the actual observed subsidence curve and the expected curve, the mining scheme adopted for coal mining under railroad was verified to be scientific and reasonable, which accumulated experience and provided a basis for future mining under electrified railroad.
