Abstract:
In order to realize fine comprehensive geophysical prospecting on water bearing abnormal bodies, based on the types classification and character analysis of water bearing abnormal bodies, the mine geophysical prospecting method and applicable conditions were studied, and the comprehensive geophysical prospecting cases were analyzed. The results showed that the coalmine water bearing abnormal bodies can be divided into water bursting sources and water conducting channels. In order to achieve accurate comprehensive geophysical prospecting, two or more mine comprehensive geophysical prospecting methods should be adopted. The mine geophysical prospecting methods include electromagnetic method and seismic method while the mine comprehensive geophysical prospecting can be applied in advanced detection of heading end, inner working face, roof and floor. The optimization of mine comprehensive geophysical detection methods should be adopted according to the character and types of water bearing abnormal bodies. And the case indicated the good effect of comprehensive geophysical detection methods on water bearing abnormal bodies.
