| 摘 要： | 内蒙古呼伦贝尔东明露天煤矿矿坑边帮地下水渗漏的问题日益严重,矿区原有的疏干降水井排水能力及效果已不能满足生产需求,同时对矿区生态环境也造成一定程度破坏。目前,对矿区周边的水文地质条件和水力联系缺乏精准全面的认识和数据。通过瞬变电磁法对矿区地下水渗漏较严重的西北部进行三条勘探线(77个物理点)勘查,结果表明该区存在三处视电阻率低阻异常带,判定其主要为含水断层(裂隙)所致;结合矿区地形、地层岩性与矿区地下水矿化度,对上述异常带进行了科学合理的综合解释,并结合新施工的疏干降水井抽水验证了上述异常的可靠性,为矿区后期布置疏干降水井圈定了靶区,对当地同类型矿区地下水渗漏灾害治理起到了应用示范作用。

| Abstract: | For the underground water leakage of pit slope in Dongming open coal mine is becoming more and more serious, the capacity and effect of drainage wells can not satisfy the production requirements, it also causes severe damage to mine ecosystem. So far, we may not have accurate awareness and data of hydrogeologic condition and hydraulic connection around mining area. In this paper, we explored three exploratory lines (77 physical points) with Transient Electromagnetic Method (TEM) on northwest part of mining area, where the underground water leakage is more serious. The results show that there are three anomaly belts of low apparent resistivity, and we found they are caused by water-bearing fault. We make a scientific and reasonable explanation with comprehensive analysis on geomorphology, lithology and mineralization degree of groundwater of mining area. Meanwhile we verify the reliability of three anomaly belts through water-pumping test from new drainage wells. The results delineate targets for drainage wells and play an exemplary role on treatment of underground water leakage in local similar mining area. |
