摘要
以马兰矿12702综采工作面为工程背景,分析了断层在工作面推进过程中的影响机理,探究了注浆加固技术和巷道加强支护技术对工作面过断层的实践。应用表明,工作面在推过断层期间,顶板应力集中不明显,巷道顶板下沉在可控范围内,工作面设备推进正常。
Taking 12702 fully mechanized coal face of Malan Colliery as the engineering background,this paper analyzes the influence mechanism of the fault in the process of advancing the working face,and explores the practice of grouting reinforcement technology and roadway strengthening support technology for crossing fault of the working face,whose application shows that the roof stress concentration is not obvious while crossing the fault,the roof subsidence of the roadway is within the controllable range,and the advance of the working face equipment is normal.
