小煤柱掘进工作面探放水技术的应用

Application of Water Exploration and Drainage Technology in Small Coal Pillar Driving Face

根据相关统计,煤矿井下透水事故在各类重大井下事故中占较大比例,透水事故的发生也反映了煤矿井下探放水工作的重要性,煤矿技术管理人员必须在加强生产经营管理的同时重视探放水工作,杜绝井下透水事故的发生。防治水是矿井设计及安全管理方面的重要课题,以一井田11#煤层406盘区8608工作面为例,结合物探结果,从采区回风顺槽可能的突水现象入手,探讨了超前探放水设计及施工过程。分析结果显示,只有合理规划布置探放水工作,才能保证工作面安全快速高效掘进。

According to relevant statistics, underground water penetration accidents account for a large proportion of all kinds of major underground accidents. The occurrence of water penetration accidents also reflects the importance of underground water exploration and drainage in coal mines. The technical management personnel of coal mines must pay attention to water exploration and drainage while strengthening production and operation management to prevent the occurrence of underground water penetration accidents. Prevention and control of water is an important subject in mine design and safety management. Taking 8608 working face in 406 panel of 11#coal seam of a coal mine as an example, combined with geophysical exploration results, the design and construction process of advanced water exploration and drainage were discussed from the possible water inrush phenomenon of the return air chute in the mining area. The analysis results show that only reasonable planning and arrangement of water exploration and drainage work can ensure safe, rapid and efficient excavation of the working face.
