摘要
利用电法勘探对冀中能源邯矿集团郭二庄矿二坑开拓揭穿的陷落柱空间赋存状态及导水性进行探测,通过在工作面施工井下钻孔进行验证。验证表明,探测结果与实际相吻合,为煤矿安全生产提供一定的地质依据。
Electrical prospecting was used to explore spatial occurrence and water conductivity of the collapsed column of Guoerzhuang Mine of Jizhong Energy Group,and verified by underground drilling.The validation showed that the results of the detection were consistent with reality and provided some geological basis for safe mining.
