摘要
老矿区普遍存在顶板暴露、裂隙发育延伸距离远的现状,实施老区挖潜钻遇顶板附近极易发生大规模涌漏同存的现象,施工风险大、成本高。本文重点介绍福川矿区新钻更新水平井钻遇顶板附近发生严重涌漏的处理措施,为国内其他地区老矿区挖潜提供参考和借鉴。
It is normal that old mine areas have problems of roofs exposure and fracture development has a long extended distance. If conducts digging and drilling near the roofs in these old mine areas, it is easy to happen large-scale gush and leakage simultaneously, and it will lead to the high construction risk and high cost. This paper mainly introduces the treatment measures for serious gush and leakage which happen near the roofs in the Fuchuan Mine Area by using updated horizontal drillings. It offers reference for diggiong and drilling in other old mine areas in China.
