Abstract With the existing information of the goafs and 3D seismic prospecting data,combined with the geophysical characteristics of the goafs,the authors performed technological extraction and comprehensive analysis of various attributes in one of the working areas in Linfen,Shanxi Province.Variance,three instantaneous parameters information,structure and root mean square were selected,which can effectively highlight the anomaly of the mined-out area,with the structure attributes being most important.A comparison with surface properties shows that the body properties are more reliable in qualitative interpretation of the mined-out area.
