邢东矿深部开采区域探查治理技术应用

Application of deep mining area exploration and control technology in Xingdong Mine

基于邢东矿进入深部区域开采以来先后发生3次奥灰出水,深部奥灰出水危险性较浅部明显增加的情况,提出了以"地面定向近水平顺层分支钻孔群"技术为核心的探查和治理方案。方案以垂向导水构造的探查与防治为重点,对构造发育区段、地层破碎区段及富水异常区进行探查和注浆加固。实践表明,该治理工程切断了奥灰水补给通道,保证了探查治理区域生产安全。

Based on three times of Ordovician limestone water in deep mining area of Xingdong Mine,Ordovician limestone water threatened deep more than shallow,directional close horizontal branch drilling group technology was proposed.Based on exploration and control of water structure of vertical guide,tectonic zone,fracture zone and water-rich abnormal area were explored and grouting.The technology cuts off the supply of Ordovician limestone water and ensures the safe mining.
