Abstract：In order to study the spatial distribution and development of ground fissures，3D seismic exploration was carried out for the area with ground fissure outcroppings in Jinzhong Basin. Data was acquired by using shooting-off-end swath acquisition-geometry survey，processed by pre-stack time migration to improve the accuracy of the fissures space and the effect of image，and interpreted for ground fissures based on the seismic multi-attribute analysis，especially the ant-tracking technique. The total area of the studied district are 4 km2，and 20 ground fissures were interpreted with 11 principal ground fissures and 9 secondary ground fissures. Some of those ground fissures were interpreted as the outcrop on the surface，while some dip all the way down to the bedrock. The ground fissures are line-like distributed from plane view with a dominant orientation of NEE. In general，they have the same direction as the major faults in Jinzhong Basin and have the distinct structural direction. From the section view，the strata on both sides of ground fissures displaced to each other with a throw of 0–40 m. In 3D space，they are horsts and grabens. 4 out of 5 ground fissures that outcrop on the surface in the studied area were confirmed by this prospecting，which indicates that the 3D seismic prospecting is an effective approach in ground fissure detection.
