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.
