摘要： 山西焦煤霍州煤电集团干河煤矿2092 巷掘进期间受上覆k8 砂岩含水层影响，巷道顶板出现淋水现象，不但
降低了巷道掘进效率，而且软化了顶板岩体，降低了顶板支护质量，甚至会引发顶板水害事故。为了2092 巷掘进安全，
避免水害事故发生，决定对2092 巷采取合理有效的探放水设计及安全技术措施。分析了2092 巷掘进期间的上覆含水层
探放水施工设计，并总结了采取的安全技术措施。从实际应用效果来看，采取探放水施工后2092 巷掘进期间共计探放
上覆含水层积水量达2 447 m3，取得了显著应用成效。

Abstract: During the tunneling of 2092 roadway in Ganhe Coal Mine of Huozhou Coal Electricity Group of Shanxi Coking Coal
Group, affected by the overlying k8 sandstone aquifer, the roof of the roadway has water dripping, which not only reduces the
efficiency of roadway excavation, but also softens the roof rock mass and reduced the quality of roof support, and even causes roof
water damage accidents. In order to make the tunneling of 2092 roadway safe and avoid water hazards, it was decided to adopt
reasonable and effective water exploration and drainage design and safety technical measures for 2092 roadway. This paper
analyzed the water exploration and drainage construction design of the overlying aquifer during driving 2092 roadway, and
summarized the safety technical measures adopted. According to the actual application effect, the total amount of accumulating
water explored and drained in the overlying aquifer reached 2 447 m3 during driving 2092 roadway after the water exploration and
drainage construction, which achieved significant application results.
