摘　　要：为解决11301回风顺槽原有留巷方案围岩控制效果不佳的问题,结合现场情况及邻近矿井留巷经验,从切顶参数、顶板补强、巷帮支护方面对留巷技术参数进行了优化,并具体给出了优化后的留巷技术方案。工程应用后,11301回风顺槽留巷段顶板下沉量、底鼓量及巷帮水平移近量分别为132、 135、 216 mm,围岩变形控制效果显著,可满足11301采煤工作面无煤柱开采需求。In order to solve the problem of poor surrounding rock control effect of the original entry retaining scheme of 11301return air crossheading,combined with the site situation and the entry retaining experience of adjacent mine,the technical parameters of entry retaining were optimized from the aspects of cutting roof parameters,roof reinforcement and roadway wall support,and the optimized technical scheme of entry retaining was proposed in detail.After engineering application,the roof subsidence,floor heave and horizontal drift of roadway sides of entry retaining section of 11301 return air crossheading were 132,135 and 216 mm respectively,and the deformation control effect of surrounding rock was remarkable,which can meet the pillarfree mining demand of 11301 coal mining face.
