ABSTRACT
Influenced by unfavorable geological process, the open-pit slope in the alpine area have presented different degrees of cracking and collapse, which seriously threatens the mine's safety production. Based on the actual situation, the natural and human factors causing slope damages were analyzed. Based on calculation and analysis, the comprehensive treatment scheme of slope brushing and earthwork clearing combined with prestressed anchorage cable lattice beam was designed. The open-pit slope was successfully reinforced according to the scheme, which successfully controlled the deformation rate of the slope, eliminated the hidden safety hazards, and ensured the sustainable mining of the mine.
