摘要
瞬变电磁法(TEM)是应用较广的一种电法勘探技术,GDP-32Ⅱ多功能电法仪是近几年来发展较快的电法勘探仪器。利用GDP-32Ⅱ多功能电法仪的瞬变电磁法(TEM)的探测功能探测煤层采空区发展尚不成熟,本文综合地面物探瞬变电磁法的应用发展技术,根据探测区的地球物理特征,运用GDP-32Ⅱ多功能电法仪,以探测斜沟煤矿采空区为例,通过对实测资料的处理和计算机绘图等综合分析,准确地探测出了采空区的位置,说明瞬变电磁法应用GDP-32Ⅱ多功能电法仪探测煤矿采空区能够取得较好的效果。
Transient electromagnetic method （TEM） is widely used as an electronic prospecting method, and the multifunction electrical tester GDP-32 Ⅱ is an electrical prospecting instrument which is developed rapidly in recent years. According to the application and development technique of geophysical transient electromagnetic method, it is founded that the tester could achieve the better results with geophysical transient electromagnetic method to detect coal mined-out areas by using the muhifunction electrical meter GDP-32＂. Taking the detection for Xiegou coal mined-out area as the example, through processing the field data, the computer plotting and the comprehensive analysis, the accurate location of the coal mined- out area is detected based on the geophysical characteristics of the detected area.
