【Abstract】 Most gcofractures of Fen-Wei basin belong to structural type, and they are placed under an united field of structural stress, forming traces of the newest fractures on surface of the crust. Hazard caused by geofraclures extending from Wcihe basin through Yuncheng basin to Datong basin. In time, the southern gcofractures occur earlier than the northern, and in intensity the southern are stronger than the northern. Now, this geofracture system is still developing and extending. Its hazard will continue at least for 20-30 years. The activity of geofracture and that of earthquake although are alike in structural genesis, but they have no genetical connection,the property and process of hazard caused by them arc not the same. The hazard of geofracture occurs slowly and near to earth surface, distributing within the linear zone of geofracture, no transverse continuity between the linear zones. So that the protection measure against hazard will be taken only within the area of 20-30 m wide. This study is very important to industrial and agricultural production, urban construction and energy exploitation of Shanxi and Shannxi provinces.更多还原
