Application research of high density resistivity method to karst geological exploration in mining area

摘要

The karst collapse is a common karst geological hazard,which greatly endangers local people's life and property safety.Hazard geological survey provides necessary basic geological data for hazard treatment in karst area,and it is also the precondition of preventing and decreasing hazard work.As a new geological prospecting method,the high density resistivity method can be applied in geological hazard survey and engineering survey extensively.It is an effective method of karst survey,which can reflect the section electrical change caused by karst development and the basic form of karst electrical abnormal body.The status of karst development,the main geological structure and fault structure of Rucheng tungsten mine area are studied by using high density resistivity method in this paper.They have got a good geological effect,and preliminary studied the cause of karst geological hazard occurred in mining area.The result provides a solid geophysical basis for the further comprehensive treatment in this area.
