Abstract
The investigation of the coal mine subsidence area by 3-D seismic prospecting method can accurately delimit gob area as well as can explain the distribution of intermediate,hallow subsidence areas,The 3-D seismic prospecting method can overcome the weakness that prospecting depth is relative shallow by traditional prospecting method-geologic radar,electrical prospecting,transverse seismic wave and so on,It can accurately provide geologic result for developing and using the old mining area that is under 30 m.
