摘要
电法勘探在探测采空区方面也有了很大的发展,高密度电法是集中了电剖面法和电测深法,适用于平原、浅层300 m的探测深度。瞬变电磁法适用于800 m的探测深度,但易受干扰。针对西石门铁矿北区和南区的探测环境不同,分别在北区采用高密度电法和南区采用瞬变电磁法进行探测,探测成果圈定采空区在大致范围,再结合传统的钻探工程,对不明采空区进行综合探测。大大降低了金属矿山探测不明采空区的盲目性和生产成本。
In recent years,electrical prospecting method prospecting mined-out area had very big development.Highdensity electrical method,which is focus on the electric profiling method and electrical sounding method,applicable in detecting the plains and shallow in depth 300 meters.The transient electro-magnetic method（TEM） is applicable to 800 meters of detecting depth,but easily distracted.According to the different environments in north area and south area of Xishimen iron ore mine,in north area and south area respectively detected by high-density electrical method TEM,detection results in delineating goaf and combine the approximate scope of traditional drilling projects,and the unidentified comprehensive detection mined-out area.This detection of unidentified goaf is more targeted and production costs reduced greatly.
