摘　　要：为进一步提升煤矿沿空留巷围岩的稳定性,在对工作面顶底板地质条件分析的基础上,采用地应力实测和监测的方式对当前支护方案的效果进行研究,并根据研究成果提出采用锚注支护对沿空留巷进行补强加固。经实践表明:锚注支护应用于工作面的沿空留巷后,实体煤帮部、底板、小煤柱帮部以及顶板四个位置的变形量均得到有效控制,而且控制效果非常好。In order to further enhance the stability of the surrounding rock of the coal mine along the hollow stay lane,Based on the analysis of the geological conditions of the top and bottom slabs of the working face,the effect of the current support scheme was studied by means of ground stress measurement and monitoring;and based on the research results,anchor injection support was proposed to be used to reinforce the reinforcement along the hollow stay lane.The practice shows that after the bolt grouting support is applied to the gob side entry retaining of the working face,the deformation of the solid coal side,the floor,the small coal pillar side and the top plate are effectively controlled,and the control effect is very good.
