摘　　要：以某煤矿N1201综采工作面胶运顺槽支护项目为工程背景,对全煤巷道进行了锚杆支护设计。通过现场应用,并对巷道变形进行同步监测,分析监测数据,评价支护效果,反馈信息优化设计,实现初步设计与工程相结合的动态设计。从理论和实践两个方面进一步验证了锚杆支护方式在煤巷中应用的可行性。Taking support in the belt conveyor crossheading at N121 fully mechanized face as the project background,the bolt support is used in the coal roadway.Through the field application,and carring on the synchronized monitor to the tunnel distortion,analyzing monitor data,the appraisal supports and protections effect,feeding back the information optimization design,the preliminary design and dynamic design are realized.the feasibility of bolt support way in the coal roadway is further verified.

关 键 词：全煤巷道 锚杆支护 监测
