摘要
巷道掘进应进行探放水工程,以石壕煤矿13112工作面下巷水文地质条件为工程背景,分析了13112工作面下巷充水因素,表明采空区积水给巷道掘进带来一定的威胁,基于此,设计了采空区探放水工程,查证了13112工作面下巷邻近采空区积水情况,并进行了疏放,保证了13112工作面下巷的安全掘进,为13112工作面安全回采提供保障。
Water exploration and drainage engineering should be carried out in roadway excavation.Taking the lower roadway hydrogeological conditions of No.13112 face in Shihao Mine as the engineering background,the lower roadway water filling factors of No.13112 face were analyzed,which indicated that the water accumulation in goaf caused a certain threat to the roadway excavation.Based on this,the water exploration and drainage engineering in goaf was designed,the water accumulation in the adjacent goaf of No.13112 face lower roadway was verified,and the drainage was carried out,which ensured the safe excavation of No.13112 face lower roadway and provided guarantee for the safe mining of No.13112 face.
