摘要
为了降低矿井水害对巷道掘进施工影响,保证施工巷道安全快速掘进。霍州煤电集团有限责任公司团柏煤矿水害防控工程技术中心通过技术研究,对煤矿探放水施工主要存在的问题进行合理分析,并对10#煤层301巷在掘进过程中提出了有效的探放水钻孔布置设计、钻孔封孔工艺以及探水施工安全技术措施,实践证明,取得了显著成效。
In order to mitigate water damage to the process of drifting in mines and ensure safe and fast driving in the coal roadway, according to technical research, the water disaster prevention and control engineering technology center of Huozhou Coal and Electricity Group Co., Ltd. analyzes the main problems existing in the construction of water exploration and drainage in coal mine, and puts forward the effective layout design of water exploration and drainage boreholes, the technology of hole sealing and the safety technical measures for water exploration and drainage in the course of excavation of No. 101 roadway in coal seam. The practice has proved that remarkable results have been achieved.
