摘　　要：东峰煤矿3201工作面设计轨道顺槽留巷1767 m。总体留巷效果达到了预期目标,但部分地段出现不同程度的底鼓、墙体倾斜、剪切、顶板下沉、帮鼓等问题。通过及时采取措施维护后,留巷复用可安全顺利回采。The 3201 working face of Dongfeng Coal Mine is designed with 1767 m of reserved roadway along the track.The overall effect of retaining roadway has achieved the expected goal,but some sections still have problems such as floor heave,wall tilt,shear,roof subsidence,side heave and so on.After taking timely measures for maintenance,the reuse of retaining roadway can be safely and smoothly recovered.
