摘要
为了解决王河煤矿10902薄煤层工作面突水问题,通过分析该工作面水文地质条件及构造分布,采用理论分析和瞬变电磁物探技术手段,对工作面突水原因进行研究,找出10902工作面出水区域中的富水区,并利用现场注浆的措施对富水区域进行治理。治理结果表明:工作面出水量由原来349m3/h的减小为130m3/h,堵水率为63%,治理效果良好。
In order to solve the water outburst problems at 10902 thin Coal Seam of Wang He coal mine, theoretical analysis and transient electromagnetic geophysical prospecting techniques are used to probe into the causes for water outburst at the coal face by analyzing the face hydrogeological conditions and distribution structure, rich water zone of the 10902 Face water outflow area is identified and governed by use of site grouting measures. Governance results indicated a good effect with the face water outflow reduced from 349m3 / h to 130m3 / h and a water shut-off rate of 63%.
