Abstract:In order to acquire the prospection effect of underground water in coal mines which are seriously threatened by water disasters in west Fujian area and the valid parameters of geophysical prospecting techniques, combined detection was carried out on the anomalous body in front of the heading face of the entry at+40 m level in a mine in Fujian Province by using the mine DC electrical method, network parallel electrical method and mine transient electromagnetic method, and the comparative analysis was made on the detection results of the water-bearing low-resistance anomalous bodies, the late driivage verification indicated that the advance detection results were more accurate. The practice showed that the detection effect of the network parallel electrical method was much better than that of the traditional D. C. electrical method, the mine transient electromagnetic method had sensitive response to the water-bearing low-resistance anomalous bodies and stronger penetration ability to the high-resistance bodies ( layers);the combined detection with various geophysical prospecting techniques can complement and verify each other and has higher detection accuracy.
