FIELD: mining.
SUBSTANCE: method for open pit mining of mineral deposits includes construction of open pit of first stage to entire depth of pool development, arrangement of overburden rocks from the open pit of first stage into outer pile, separation of the open pit field into face and dump portions, placement of overburden rocks with subsequent extraction of the deposit to the inner dump. According to invention, the face portion of the open pit field is mined by inclined active benches, dump portion of the open pit field is formed by inclined dump tiers. The inclination of active benches and the inclination of dump tiers are performed in opposite directions, and haulage communication between said active benches and dump tiers is carried out along horizontal transport berms made along the strike of deposit along the edges of the open pit field.
EFFECT: providing cyclicity of mining operations, uniform loading on personnel and equipment when developing the deposit.
