瞬变电磁法对矿井不良含水构造体的探测应用

Application of TEM Method in Detection of Poor Water-bearing Structures in Mine

为查明煤矿井下水源分布区域及构造性质导水通道,制定有针对性的防治水措施,避免透水事故发生,提出采用瞬变电磁技术在掘进工作面进行超前探水。针对成庄矿15号煤层某工作面突水隐患问题,依据矿井水文条件及工作面构造导水因素特征,设计对应的瞬变电磁施工方案。根据探测结果,结合打钻验证,在实际工作中成功揭露含水体,表明应用该方法推断准确、切实可行,可为矿井安全开采提供有效的地质保障。

In order to find out the distribution area of underground water source and the structural natureof the coal mine waterway, we have formulated targeted water control measures to avoid the occurrence of flood-ing accidents. We propose the use of transient electromagnetic technology to advance water exploration on theworking face of the tunnel. Aiming at the hidden danger of water inrush in a working face of No. 15 coal seamin Chengzhuang Mine, the corresponding transient electromagnetic construction scheme is designed based onthe conditions of the hydrology of the mine and the characteristics of the construction hydraulic conductivity.Starting from the detection results and drilling verification, the method successfully disclose the water-bearingbody, which indicates that this method is accurate and feasible, and it can provide effective geological protec-tion for safe mining.
