摘要
煤层附近的富水区和采空区积水严重威胁着煤矿的生产安全,传统的地球物理方法在煤矿水害勘查工作中得到应用的同时,新的更先进的物探方法不断涌现,本文通过实例阐述了瞬变电磁法在探测采空区积水和煤层顶底板富水区中的实用性和有效性。
Watery zones adjacent to coal seams and water in gob area are seriously imperiling coalmine's safety. Some new advanced geophysical prospecting methods are coming forth to explore the coalmine flood damage while the traditional methods still in use. Through cases, theutility and the effectiveness of TEM used in detecting water in gob area and roof - floor wateryzones are expounded.
