摘　　要：邢台矿7700采区因F12断层的存在留设了2号煤防水煤柱,为解放煤柱区煤炭资源,提出采用地面区域治理技术进行探查和注浆改造。通过定向钻进技术,对F12断层进行精细勘察,分析其含导水性;设计注浆治理工程方案,采用立体式治理模式,对奥灰含水层进行注浆改造。工程实施后,发现F12断层存在向矿井边界内部偏移的现象,且水文地质条件复杂,注浆工艺优化未见明显效果,从工程施工治理难度及经济效益考虑,建议该工程暂缓实施。Due to the existence of F12 fault in 7700 mining area of Xingtai Mine,No.2 coal waterproof coal pillar was set up.In order to liberate the coal resources in the coal pillar area,the ground regional control technology was proposed for exploration and grouting transformation.Through the directional drilling technology,the F12 fault was finely surveyed and its water conductivity was analyzed.The grouting control project scheme was designed,and the three-dimensional control mode was adopted to carry out grouting transformation of the Ordovician limestone aquifer.After the implementation of the project,it was found that the F12 fault migrated to the interior of the mine boundary,and the hydrogeological conditions were complex.There was no obvious effect on the optimization of the grouting process.Considering the difficulty of engineering construction and economic benefits,it was recommended that the project should be suspended.
