Abstract: Based on the roadway layout and surrounding rock control of 2302 upper drift disturbed driving along goaf in Yili Yongning Coal Chemical Co., Ltd, the background mining and numerical simulation were used to analyze the advanced mining stress and lateral support of the 2301 working face. The range of stress influence is determined. The advance 80m and the lag 100m are the influence range of the disturbing disturbance. On this basis, the bearing evolution law of the surrounding rock of the different coal pillar width 2302 is further analyzed, and the reasonable narrow coal pillar of the 2302 upper channel is determined. The width is 6.0m. Finally, the reinforcement support technology of the anchor cable support and the single hydraulic props with the π beam is proposed in the range of the disturbance, and the industrial test is carried out on the 2302 groove. The results of the mine pressure observation show that in the extra-thick coal seam, the 6.0m coal pillar width and the surrounding rock control technology of the excavation along the goaf are disturbed. The research results have important application value for alleviating the problem of tight mining succession.
