In the method for destruction of high strength rock massif pilot relieving holes are arranged on local sites in whole length of rock massif with given sequential cycles through simultaneous group drilling, and depth of relieving wells is made not less than cutting volume of power-loader. In the installation for arrangement of pilot relieving holes drill carriages are installed in different in height levels and are maximally concentrated to linear row that alternates with possibility of group drilling, this can be set by carriages in each level.
