摘　　要：为了解决部分矿井采掘接替紧张的问题,在上区段工作面回采时,在采空区边沿留下窄煤柱进行下区段所需巷道的掘进,就是所谓的迎采动面沿空掘巷。以山西大同某矿采区为例,2207为其轨道顺槽,2205为上一区段的运输顺槽,用FLAC^(3D) 模拟迎采动面巷道的停掘位置。In order to solve the problems, when the upper section of the working face is mining, thegoaf leave the narrow coal pillar that is for excavation of next section required roadway ,so it is calledgob side entry driving roadway. A mining area of Datong mine in Shanxi is taken as an example, 2207is the track crossheading , and 2205 is the transportation trough of the upper section. The stoppingposition of the roadway is simulated by FLAC3D

关 键 词：迎采动面 停掘 沿空掘巷
