Abstract: The sueface seismogeologic condition in Weishanhu Lake area is very comlicated.We used 3D seismic attribute technique in the area, improved the coupling effect of radiodetector, and got high SNR 3D seismic data.Explaned the data with 3D visualization, correlative data system and seismic attribute technique, the method improved the ability to identify small underground geological strcture and seismic anomaly body.It perfected the the 3D seismic prospecting technique, and enlarged its applied range, and provided a useful method for the tectonic and geological problem in coal mining.
