Mode of ore release from uprising branched stores

Abstract

One of the polymetallic deposits of the Union, where vein thickness varies from a few centimeters to 2-3 m and dip angles from 25 to 90°, is represented by a variety of vein forms, among which branching ore bodies are widespread. The development of veins branching along the uprise is particularly difficult, as the acceptability of a productive system with ore storages on thin veins is determined by the possibility of partial release of ore from the branched storages to the common floor drift. This determines the choice of the development system option,* the volume of preparation and cutting works, labor productivity and ore cost. The possibility of partial release at simultaneous stripping in all branching veins (main vein and apophysis) is determined by the rate of ore flow from the stores along the vein and apophyses.
