Method for destruction of rock massif with high strength I coal seam includes combine extraction of coal and rock, drilling in replacement rock massif advancing weakening wells arranged at distance one from another. Advancing weakening wells are arranged on local sections by whole length of rock massif with given sequential cycles through simultaneous group drilling with formation of maximally concentrated destruction effect on specific unit of area of rock massif, at that depth of weakening wells is made not smaller than width of cover of combine that destructs area of rock massif.
