摘要
针对15109回风顺槽前期掘进期间受邻近15107采空区积水影响,巷道顶板及巷帮出现淋水现象,严重威胁着巷道安全快速掘进的问题,南河煤矿地测防治水科分析了巷道掘进前期探放水施工存在的不足,并根据巷道掘进现状,对采空区提出了合理有效的探放水设计,并对探放水施工期间提出了合理有效的安全技术措施。通过实际应用效果来看,探放水设计优化后巷道在后期掘进过程中共计探放采空区积水2387 m^(3),探放水施工巷道未出现围岩淋水现象,取得了显著应用成效。
For the 15109 backwind downchannel during the early excavation affected by the adjacent 15107 mining area water,the roadway roof and roadway gang drenching phenomenon,a serious threat to the roadway safety and rapid excavation,this Nanhe coal mine geological survey water control section analyzed the shortcomings of the roadway excavation preliminary water detection and release construction,and according to the roadway excavation status,a reasonable and effective water detection and release design for the mining area,and the water detection and release construction During the construction period,reasonable and effective safety technical measures were proposed,through the actual application effect,after the optimization of water exploration and release design,a total of 2,387 m^(3) of water was explored and released from the mining area during the later roadway excavation,and no surrounding rock drenching phenomenon occurred in the water exploration and release construction roadway,which has achieved significant application results.
