Abstract:By using transient electromagnetic method and loopshaped sounding method, comprehensive exploration has been carried out in waterrich area in coal mine. Transient electromagnetic method is convenient in construction. It is particularly sensitive to low resistance containing water, and affected by the volume effect lowly with high resolution. It will control the scope of waterrich area from plane. Loopshaped sounding can detect the apparent resistivity change of strata in different direction, and control the groundwater flow direction. Combination of two methods can control the area from plane, and control regional water extension. For the detection in waterrich area, the use of comprehensive geophysical exploration can make the detection more accordance with the actual results. Combination of the two methods can help detecttion research in this area in the future.
