Abstract
The paper concerns an interpretation of high-precision gravimeter observations in the Upper Kama Potash Salt Deposit. The studies aim to detect the mining-induced softened areas in undermined rock mass. It is found that the gravity field transformants exhibit induced softening areas as flat inclined negative anomalies that intersect the undermined rock mass from top downward. The spatial location of the induced softening areas in rock mass is determined.
