METHOD FOR HIGH BROKEN-PROFILE BENCH SLOPE PROTECTION AGAINST LANDSLIDE

摘要

FIELD: mining, particularly to consolidate or to protect pit sides against landslide during pit operation.;SUBSTANCE: method involves laying transversal members connected to ropes along slope, wherein the ropes are fixedly secured to anchors located in upper bench berm; drilling inclined wells extending to bench slope; installing next anchor along lower edge of upper berm and drilling next inclined well cluster. Suspending net to bench slope and pulling down ropes from upper berm through drilled inclined wells so that the first rope ends extend from bench slope; lowering the rope ends to lower berm and securing thereof to transversal members arranged above the net, wherein the transversal members are installed beginning from lower berm; tightening the ropes and fastening the second rope ends to anchors.;EFFECT: increased operational safety and decreased labor inputs for bench slope consolidation.;1 ex, 2 dwg
