摘　　要：针对淮南地区邹庄煤矿3024采区瓦斯抽放泵硐室的支护出现失稳变形这一情况,文章分析了支护失稳变形的破坏机理,提出了复杂围岩条件下的全封闭U型钢架及锚网喷注的联合支护方式,现场应用65d后支护变形趋于稳定,表明该支护形式在复杂围岩条件下能够有效控制动压巷道围岩变形。According to the stability lost and deformation occurred in the support of the gas drainage pumping chamber in No.3024 mining block of Zouzhuang Mine in Huainan Mining Area,the paper analyzed the failure mechanism of the support stability lost and deformation and provided the combined support mode with the full closed U steel type arch support and the bolt-steel mesh-shotcreting under the conditions of the complicated surrounding rock.With the application of the combined support mode after 65 days,the support deformation was stable in tendency and thus showed that the support mode could be effectively control the surrounding rock deformation of the dynamic pressure gateway under the complicated surrounding rock condition.
