摘要
在采掘时,因陷落柱导水而发生透水灾害会给矿上造成巨大的经济损失,如果在采前对采区的地质异常体探测清楚,就可以进行治理钻孔的施工,避免因盲目钻探而造成的损失。瞬变电磁法是水文地质勘查中有效的地球物理勘探方法之一,对低阻体反应灵敏。
During the period of excavating,water bursting in mines disaster happened because of the karst collapse column contains water and always bring about great economic loss to the mine. If anomaly geology in the mining area can be explorated clearly first of all ,we can carry out drilling to control the water and this will avoid the spending brought by drilling bindly. The transient electromagnetic method is one of the effective methods of geophysical exploration in the hydrogeology exploration,it has good reaction to the low resistivity thing.
