Abstract: To solve the problem of severe deformation of roadway under the influence of advanced abutment pressure in the eastern IV district of Lucun Coal Mine, this paper uses the methods of theoretical calculation, borehole peep, numerical simulation and in-situ observation of roadway deformation to determine the range of surrounding rock loose range, and optimizes the original roadway support mode. It is concluded that the loose range of surrounding rock is 2.12 m under the action of advanced abutment pressure. Based on this, the optimized support scheme of “bolt-mesh-anchor + steel belt” can effectively control the deformation of surrounding rock of roadway and meet the needs of field production. Engineering practice has proved that the combination of various research methods can more accurately locate and grasp the actual production conditions on site, and can propose more effective roadway support scheme to ensure safety production on site and save the production cost of support.
