Abstract The seismic wave CT(Computerized Tomography) is a high resolution geophysical method containing abundant information,and hence it is very suitable for engineering geological exploration.Grouting filling,as a goaf treatment scheme,has been used frequently in recent years.Owing to the considerable uncertainty of the grouting slurry position and reinforcement effect after the grouting treatment,it is difficult to conduct quality examination on the basis of traditional sampling and compactness methods.Due to its own advantage,seismic wave CT has become a suitable choice for grouting quality detection,and it has achieved good results in practical applications.
