METHOD FOR ARRANGEMENT OF NON-WORKED SIDE OF QUARRY Russian patent published in 1997 - IPC

Abstract RU 2084633 C1

FIELD: mining industry. SUBSTANCE: method relates to opencast mining in quarries and pits. Reduced amount of overburden removal operations is achieved by maximal bringing towards each other of design and stable angles of slopes of non-worked side. Improved safety of mining operations at extreme contours is obtained due to elimination of dangerous operations of removing ground from protective berms and placing it at sites of crumbling down and falling of ground. Protective berms are formed and they need no cleaning, and their width and position ensure equality of design and stable angles of slopes in non-worked side. EFFECT: high efficiency. 1 cl, 4 dwg , 1 tbl
