瞬变电磁法与激发极化法在采空积水区探测中的应用

为更加准确地探测采空积水区范围，根据采空区积水对安全生产的影响程度，突出水患调查重点区域，采用多种物探手段开展采空积水区水患调查和勘查工作。从基本原理和数据处理方面对瞬变电磁法与激发极化法进行了介绍，通过工程案例分析，对这两种方法在采空积水区探测方面的应用效果进行了探讨。研究结果表明，采用瞬变电磁法与激发极化法进行综合探测与解释，所推断的采空积水区范围更为准确，钻探验证结果与推断情况较为一致。

Application of Transient Electromagnetic Method and Induced Polarization Method in Gob Water Detection

In order to more accurately detect the scope of the gob water, investigation and exploration were carried out on the gob water flood in the serious gob water flood area according to the influence degree of the gob water on the mine safety production by using a variety of geophysical methods.Introduction was made on the transient electromagnetic method and the induced polarization method from the aspects of their basic principle and data processing, and through the analysis of the engineering cases, discussion was made on the application effect of two methods in the gob water detection. The research results showed that using the transient electromagnetic method and the induced polarization method for comprehensive detection and interpretation could more accurately inferred the gob water scope, and the verification results by exploration boring was more consistent with the inference.
