Abstract: In order to obtain the best scheme of bolt support in Beiling Coal Mine roadway, considering the influence of inter row distance of bolt and anchor cable on supporting effect, FLAC^3D analysis software is used to simulate five kinds of different spacings and five different rows. Based on the plastic zone distribution, the horizontal stress distribution and the vertical stress distribution and the displacement of the roadway roof and floor, the reasonable bolt and anchor support can effectively prevent the plastic zone expansion, effectively protect the roof. The number of surrounding rock damage and failure form is different with the difference of inter row distance of bolt and anchor cable. Increasing the density of support can make the surrounding rock avoid tensile stress, and improve the bearing capacity of surrounding rock. Reasonable anchor and anchor cable can effectively control the roof subsidence.
