Abstract
A method for dump formation in mode of controlled deformations of rocks includes filling the dump level with support ledge to total height equal to 1.1-1.5 of the limiting height of the slope, with fixation of shear deformations of rocks in zone of formation of the support ledge, after filling the level to the width of the dump cut excavator is displaced to leveled plane within the front support ledge, and the cycle of filling is repeated, and displacement of excavator to neighboring site and following filling of the next dump cut is carried out at split coming to existence. The initial cycle of filling rocks of an one-level dump with temporary support ledge is carried out to a worked out deep pit filled with underground waters, with abrupt angles of inclination of the sides of the dump cuts with width A.
