FIELD: construction.

SUBSTANCE: method includes compaction of previous tier beach zone wastes under build-up dam intended for erection on the beach of previous tier, and arrangement of road from filtering material under upstream shell of this build-up dam. Development of wastes in beach zone pit of previous tier is carried out with a single-bucket excavator that moves along the road at a safe distance from pit. Worked wastes are laid in layers with compaction into body of build-up dam. Excavator lays wastes on the road according to downstream pattern. Compaction of beach silting wastes under build-up dam and wastes of its body is carried out by means of dynamic action. Compaction of wastes is carried out mostly by ramming shocks along surface of wastes, and development of wastes in pit is carried out with single-bucket excavator equipped mostly with dragline.
