摘　　要：白云岩作为建材原料被广泛运用,但在白云岩矿山开发过程中存在着许多问题,其中就包括不良地质体对矿山工程的影响。针对该问题,在矿山前期地质勘查过程中,本文采用等值反磁通瞬变电磁法、高密度电法两种物探方法对岩溶发育重点区域的隐伏断裂带、溶洞等不良地质体进行了勘查。结果表明,两种物探方法在白云岩矿不良地质体勘查中均取得了较好的勘查效果,基本能够查明工作区内覆盖层厚度变化情况、断裂带分布情况及隐伏岩溶的发育形态及空间位置。2种物探方法的勘查成果相互印证,提高了勘查结果的准确性和全面性,为矿山开采设计及后期安全生产提供了技术支持。Dolomite is widely used as a building material,but there are many problems in the development of dolomite mines,including the influence of bad geological bodies on mine engineering.In order to solve this problem,two geophysical exploration methods,equivalent inverse magnetic flux transient electromagnetic method and high density electrical method,were used to explore the hidden fault zone and karst cave in the key karst development area.The results show that the two geophysical exploration methods have achieved good exploration results in the poor geological body exploration of dolomite ore,and can basically identify the change of overburden thickness,the distribution of fault zones,and the development form and spatial location of buried karst in the working area.The exploration results of the two geophysical exploration methods confirm each other,learn from each other,improve the accuracy and comprehensiveness of the exploration results,and provide technical support for the mining design and later safe production.
