瞬变电磁法在煤矿断层导水性勘查中的应用

Application of Transient Electromagnetic Method in the Exploration of Water Conductivity in the Faults in Coal Mine

煤矿断层导水是引起煤矿水害问题的主要因素之一,对煤矿断层的导水性勘查与评价是煤田水文地质研究中的重要课题,也是煤矿采区布置与安全开采必须解决的问题。在煤矿开采初期查明矿区内断层构造的空间分布及其含导水性,对指导煤矿安全生产具有重要的意义。在充分收集新安煤矿矿区地质、水文及物探资料的基础上,利用瞬变电磁技术,对区内断层等构造的含导水性进行了勘查,取得了良好的效果,为煤矿的开采设计和施工提供了参考依据,有效地预防了煤矿开采过程中安全事故的发生。

Water conductivity in the faults in coal mine is major element which caused coal water problems. Explo-ration and evaluation ol water conductivity in the faults in coal mine are an important research subject. It is also an issue which should be solved in safe coal mining and mining layout. In this paper,it is pointed out that the spatial distribution of fault structures in the exploration area in the early stage of coal mining and its water bearing capacity are of great significance to guide the safety production of coal mines. Based on collecting geological, hydrological and geophysical data of Xin^an coal mine,by using transient electromagnetic prospecting technology,water conduc-tivity and water bearing have been explored and achieved good results. It will provide some references for the design and construction of coal mining,and effectively prevent the occurrence of safety accidents in coal mining process.
