英文摘要：

To solve water disasters of the Cambrian limestone in the seventh Coal Mine, the transient electromagnetic method were used to explore aquifer＇s waler-bearing of the Cambrian in the ventilation entry and conveyor entry of 21160.Based on the detection of data, 6 possible water-rich areas are concluded, three water-rich areas are identified, eomprehensive comparing field exploration conditions and geological data and it provides technical support for the safe production in coal mines.
