Abstract With the exploitation of the coal seam during coal production,more and more underground goaf areas will occur,and the geophysical properties of the goaf and its overlying strata will obviously change correspondingly.Seismic exploration can effectively distinguish structures with obvious differences in physical character.Using the three-dimensional seismic exploration technology,the author analyzed the reflection wave characteristics of the goaf,summed up the factors affecting the resolution in seismic data acquisition and the key technique for goaf data processing.Exploitation verification shows that the three-dimensional seismic technology is feasible and effective in goaf exploration.
