METHOD FOR CONTROLLING DUMPS AT SLOPES Russian patent published in 2004 - IPC

FIELD: mining industry.

SUBSTANCE: method includes controlled displacement of dump due to use of natural displacement of dump along slanting flexible layer, formed at the first place before placement of rock solids in a dump by layer of rock solids of cold period of dump forming including snow and on this layer rock solids of warm season are placed, or oppositely, first, a layer of warm season rock solids and on it rock solids of cold season are placed (contact zone - zero degrees), then, onto slanting flexible layer opening rock solids are placed first at narrow front, then at broad front when dump limits approach quarry limits, to provide for in case of warm interaction of rock solids in slanting layer a creation of maximum displacing forces and displacing the dump onto gently sloping portion of slope with lower need of rock solids reexcavation. In case of restarting dump forming with use of slanting flexible layer a gradual filling of slope with opening rock solids is achieved.

EFFECT: higher adaptability to use of process for controlling movement of dump on a slope.
