FIELD: mining industry, opencast mining. SUBSTANCE: the offered method includes formation of safety berms, which are not subject to cleaning. Width and position of berms provide for equality of design and stable angle of slope of nonmining flank and exclusion of hazardous operations of berm cleaning. EFFECT: reduced volume of stripping operations due to maximum convergence of design and stable angles of sloe of nonmining flank, improved safety of mining operations at limit contours due to elimination of hazardous operations for removal of rock from safety berms. 1 cl |
