摘要
FIELD: mining.;SUBSTANCE: in an excavation method of a useful deposit at fan-like advance of scope of mining operations, which involves advancing of a permanent and working trench, installation of transport communications, excavation of a useful deposit and overburden rocks by treatment of wedge-shaped blocks, according to the invention, development of wedge-shaped blocks is performed at two stages as per a shuttle-type scheme without any shifting of transport communications with preliminary formation of an advancing recess at a turning point of transport communications in the direction of the open-pit field boundary on condition of parameters of the advancing recess L, B providing minimum development of a wedge-shaped block by value Bmin.;EFFECT: uninterrupted production of a useful mineral along the whole scope of mining operations.;2 dwg
