摘　　要：为了解决伊田煤业沿底掘留厚顶煤开切眼的围岩控制问题,通过钻孔窥视分析了顶板岩层结构,提出了顶板采用锚杆支护+锚索补强、巷帮及时采用高强锚杆支护的支护方案,并确定了相关支护参数。试验表明:切眼成巷后顶底板变形大于两帮变形,在锚网+锚索+架棚临时支护的共同作用下,巷道围岩稳定。In order to solve the problem of surrounding rock control in Yitian Coal Industry,the roof rock structure is analyzed by drilling hole peep,and the support scheme of roof bolt support+anchor cable reinforcement and highstrength bolt support in time is put forward,and relevant support parameters are determined.The test results show that the deformation of roof and floor is greater than that of two sides after the cut is completed,and the surrounding rock of roadway is stable under the combined action of bolt mesh,anchor cable and temporary support of shed.
