FIELD: mining; applicable in prevention of collapse earthquakes at rock salt mines. SUBSTANCE: method includes mapping of karst cavities occurring above water-protective formation in region of salt deposit brachy-anticline folds. The, mine workings driven under karst cavities are filled with stowage material and karst cavities are stowed through holes drilled from surface. EFFECT: prevented collapse earthquakes at potassium rock salt mines. 3 dwg
