摘　　要：3-1煤溜煤眼下口位于4-2煤胶运大巷上部,下锁口施工空间小,同时不得影响主运输系统。本次主要对困难条件下装载硐室的施工方法和支护工艺进行分析,在主系统正常运行的情况下进行扩巷,下锁口工艺由原设计的现浇钢筋混凝土板、梁改为工字钢梁支护,优化了支护工艺,缩短施工工期,可在相似工程进行推广应用。3 -1 coal sneaked in the coal is located in the 4 -2 coal plastic upper alleys,lock under construction the space is little,shall not affect the transport system at the same time.The main construction method of loading cavern under difficult conditions and the supporting technology is analyzed,under the condition of the normal operation of the main system to enlarge lane,lock technology under the original design of the cast -in -place reinforced concrete slab and beam to beam support,optimized the supporting process,shorten the construction period,can be applied in the similar engineering.
