Zusammenfassung:	Method for restoration of deep open pits includes filling of worked-out space with opening rocks, formation of support wall. Dump cuts are filled in layers along one of the sides in direction to opposite side. At the end stage of filling of each dumpcut in its upper part with excavator from one site in arc with minimal unloading radius one fills lump rock. That rock under effect of own weight falls down, pushes the extension rock to the level of natural slant and forms support wall of broken mass in the lower part of dump cut with slant angle smaller than natural one. The invention provides formation with excavator in process of dump formation of slant of dump cut at level of natural one, excludes possibility of equipment fall at cut site, together with extension rocks.
