Abstract: This paper presents a case history of the application of the highdensityresistivity method to the exploration of Shanxi bauxite deposit in the goaf area. The vertical and horizontal limits of the bauxite mine were determined from back analysis of the abnormal effect of the high and low resistance values. The deposit limits determined by the highdensity resistivity method were also verified by the exploratory borings. The results indicate that the geophysical exploration method is a reliable method in the exploring the bauxite mine deposit in the goaf area.

Key words: bauxite deposit, high and low resistance anomaly, high density electric method, goaf area
