FIELD: mining.
SUBSTANCE: invention refers to mining and can be implemented at open excavation of mineral deposits. The pit border consists of banquettes with off-ramps for dump-trucks of heavy and light payload, of piles of stripped rock and of the banquette with the off-ramp for dump-trucks of light payload, which are arranged on the banquette for dump-trucks of heavy payload and are separated with a protective bank out of stripping rock.
EFFECT: increased efficiency of excavation due to reduction of cost for transporting stripped rock with dump trucks from lower part of pit.
