摘　　要：为保证6118工作面运输顺槽沿空留巷时巷道围岩的稳定,运用理论分析结合现场实测的方法,对深井沿空留巷巷旁支护阻力进行具体分析,并结合6118工作面地质条件对沿空留巷的支护方案进行具体设计,并通过矿压监测对沿空留巷的支护方案进行验证分析。结果表明:支护方案实施后,6118运输顺槽顶板的最大下沉量为600mm,两帮的移进量为340mm,保证了沿空留巷围岩的稳定。In order to ensure the stability of the surrounding rock of the roadway when the 6118 working face is transported along the goaf, the theoretical analysis and the field measurement method are used to analyze the supporting resistance of the roadway along the deep roadway,and the geological conditions of the 6118 working face are combined. The specific design of the support scheme along the empty roadway is carried out, and the support scheme of the roadway along the goaf is verified and analyzed through the mine pressure monitoring. The results show that after the implementation of the support scheme, the maximum sinking amount of the 6118 transporting trough top plate is 600 mm,and the displacement of the two gangs is 340 mm, which ensures the stability of the surrounding rock in the retaining lane along the empty road.
