摘要
瞬变电磁法对一些低阻体反应较强,在煤矿井下水文地质勘察中有广泛应用。采取该方式可测定含水构造、地下溶洞等不规则水体,规避煤矿开采风险。针对煤矿开采中采空区积水及含水层分布,分析了瞬变电磁法在某煤矿水文地质勘查中的实际应用效果,为煤矿开采合理发展奠定坚实基础。
Transient electromagnetic method(TEM)has strong response to some low resistivity bodies and is widely used in underground hydrogeological survey in coal mines.This method can be used to measure irregular water bodies such as water-bearing structures and underground karst caves to avoid the risk of coal mining.Aiming at the water accumulation and aquifer distribution in goaf during coal mining,the practical application effect of transient electromagnetic method in hydrogeological exploration of a coal mine is analyzed,so as to lay the foundation for the rational development of coal mining.
