| Abstract: | The water-bearing structure developed widely on the roof and footwall of mining face can be a major hazardous factor of water bursting in the mining shaft because of the redistribution of ground stress and destruction of waterproof stratum during recovery process. The investigation shows that it is an effective measurement to use ground transient electromagnetic method for detecting the structures on the roof and footwall of underground mining face and to find anomalous objects in coal mine. The simple principle of the ground transient electromagnetic measurement is analyzed and a suitable assembled equipment form with multiple circles and small loops is selected to detect water-bearing structures in different locations of underground mining face aiming at current frequency occurring hazards of water bursting in coal mine. |
