摘　　要：为确定哈尔乌素露天矿大阴塔采空区的准确位置,保证采空区以上工人和设备的安全生产,采用瞬变电磁物探法勘探,按设计和ISO9001:2008质量认证体系要求施工,经过数据的常规处理、预处理和地形校正,确定了勘探目标的视电阻率,通过定性、定量和综合解释方法分析了视电阻率的变化规律,并结合地质资料对采空区进行了研究,结果表明:勘探区6#号煤东南部可能存在2个采空区,效果明显。In order to determine the accurate location of Dayin Tower goaf in Ha’erwusu Open-pit Coal Mine,and ensure the safe production of workers and equipment above the goaf,we adopt transient electromagnetic geophysical exploration method,use electromagnetic method detector according to the design and the requirements of ISO9001:2008 quality certification system construction.After routine processing,preprocessing and topographic correction of the data,the article determines apparent resistivity of the exploration target.Through the qualitative,quantitative and comprehensive interpretation methods to analyze the law of apparent resistivity change,we study the goaf in conjunction with geological data.The research results show that in the southeast of No.6 coal in the exploration area,there may be 2 goafs with obvious effects.
