Abstract: With the increasing of integration, mergers and acquisitions of the coal mines in China, the survey of the goaf is paid more and more attention to in recent years. The limitations of geophysical conditions of the goaf make it always avoided by 3D seismic exploration as the blind area. However, the development of 3D seismic exploration of coal fields allows the goaf survey or detection to become possible.Taking the 3D seismic exploration of the panel of the Wangjialing coal mine in Shanxi as an example, this paper analyzed the seismic response characteristics of the goaf seismic profile and the characteristics of changes of seismic attributes in it, and showed that the characteristics of both seismic profile and seismic attribute on the coal goaf are all obvious, hence the coal goaf survey by 3D seismic prospecting is feasible
