摘要
郭家河煤矿受顶板离层水害威胁较大,为保障回采工作面安全回采,选用三维高密度电法对工作面回采过程中的顶板富水性进行动态监测,运用切片技术对数据体进行切割,确定了矿井水的位置与赋存状态,在此基础上设计钻孔进行疏放,保证了工作面回采安全。
Guojiahe Coal Mine is greatly threatened by the water hazard of roof separation layer.In order to ensure the safe mining of the working face, three-dimensional high-density electrical method is used to dynamically monitor the water abundance of the roof during the mining process of the working face.Slicing technology is used to cut the data volume, and the location and occurrence state of the mine water are determined.On this basis, drilling holes are designed to dredge to ensure the safety of the mining face.
