摘　　要：为进一步查明治理区域内可能存在的导水构造,阻断奥陶系灰岩水通过垂向隐伏导水通道进入矿井,为此新集矿开展以探查垂向隐伏导(含)水通道为目的的1煤组开采底板灰岩水地面超前区域探查治理工作。为对2301采区(局部块段)底板灰岩地面超前区域探查治理效果进行评价,通过钻孔轨迹、探查评价、注浆治理评价三个项目采用权重得分方法,综合得出了地面区域治理效果良好。井下钻探、物探及巷道实际揭露验证说明了地面超前区域探查治理工程效果评价良好,证实了评价的可靠性。To further identify the possible water-conducting structures in the treatment area,and to block ordovician limestone water from entering the mine through vertical concealed water diversion channels,the exploration and treatment of the ground advanced area of bottom limestone water were carried out in No.1 coal group of Xinji Mine.The weight score method was used to calculate the drilling trajectory,exploration evaluation and grouting treatment,and the effect of exploration and treatment of floor limestone ground advaced area in 2301 mining area(partial block)was evaluated.The comprehensive calculation has shown that the treatment effect of the ground area is good.The results of downhole drilling,geophysical prospecting and actual exposure of roadway verify the positive effect of the exploration and treatment project in the advanced area on the ground,which confirms the reliability of the evaluation method.
