瞬变电磁法在富源县阿形煤矿采空区勘查中的应用

The Application of Transient Electromagnetic Method(TEM)in Mined-out Area's Exploration in Axing Coal Mine of Fuyuan County

利用物探手段主要是"瞬变电磁法",进行实地探测以初步确定采空区范围,未开采区域主要寻找断层富水区段。通过对探测数据的综合分析,获取了采空区、地层、富水断层的物性参数,以定性和定量分析相结合的方法,划分出了地层、断层富水区段和采空区的范围。

By using geophysical prospecting method especially TEM, the scope of mined-out area was initially identified through the field detection, and in the virgin area the main task is to seek the fault＇s water-rich section. Through the comprehensive analysis on the exploratory data, the physical parameters of the mined-out area, stratum and water-rich fault were obtained, and by using the method of combining qualitative analysis and quantitative analysis, the scopes of the stratum, fault＇s water-rich section and mined-out area were marked off.
