Abstract: Aiming at the problems that the surrounding rock of 6.0m small coal pillar roadway in the third panel area of Tashan Coal Mine of Tongmei Group is complicated and difficult to control the stability of surrounding rock, the FLAC3D numerical calculation and analysis method is used to simulate and study the change of coal pillar stress during the mining process of 8311 working face Based on the support scheme for small coal pillars reinforced with roofing cables and roof support, the results of on-site monitoring and analysis show that the surrounding rock control effect of this support scheme is good, which can meet the safety production requirements of the roadway during the service period.
