FIELD: mining industry, particularly for mining gently sloping potash salt beds.
SUBSTANCE: method involves delineating stall by excavations; mining stall stock by means of faces along with keeping crunches of existent excavations by auger towards crunches by cutting seam along the full thickness hc; performing cutting between stalls in crunch center after excavation destruction; drilling out potash salt seams with the use of stopping wells in direction to exhausted space, wherein drilling-out is performed for B=4hc width and distance between stopping wells Δ is equal to 3hc.
EFFECT: increased safety and increased degree of sylvinite mineral extraction.
