FIELD: geotechnology; applicable in elimination of underground cavities. SUBSTANCE: method for elimination of dry and partially filled with liquid underground cavities in rock salt includes filling of cavities with loose material whose density and hardness exceed the respective characteristics of rock salt, freeing of process hole within the interval of salt mass from pipes and remaining cementing, filling this interval of hole with salt and cementing of remaining upper part of hole. EFFECT: excluded rising to the surface of cavities and reliable isolation of contaminated liquid in cavity from water bearing horizons and earth surface. 2 cl
