摘要
井下探放水是煤炭安全开采的保障措施。开元矿15402巷道顶板存在采空区积水问题,给巷道掘进带来隐患,须进行探放水措施。根据开元矿15402巷道实际状况,制定详尽的探放水作业方案,并对施工作业中的注意事项进行阐述。探放水方案实施后,对放水量和探放水钻孔水压进行监测,表明探放水作业达到预期的效果,共探放水12万m3,为巷道安全掘进奠定了基础。
Underground water exploration and drainage was a safeguard measure for safe coal mining. The roof of No.15402roadway in Kaiyuan Mine had the problem of water accumulation in goaf, which brought hidden danger to roadway excavation, and water exploration and drainage measures should be carried out. According to the actual situation of No.15402 roadway in Kaiyuan Mine, a detailed scheme of water exploration and drainage operation was formulated, and the matters needing attention in construction were expounded. After the implementation of the water exploration and drainage scheme, the water discharge and the water pressure of the water exploration and drainage borehole were monitored,indicating that the water exploration and drainage operation achieved the expected effect. And a total of 120,000 m3 of water was explored and discharged, which laid a foundation for the safe excavation of the roadway.
