METHOD FOR MINING OF INCLINED ORE BODIES Russian patent published in 1996 - IPC

FIELD: mining. SUBSTANCE: method for mining of inclined ore bodies includes dividing of extraction district into rooms oriented to the dip, formation in the lower part of the room of undercut space and ore receiving workings by layer breaking of ore by ring sets of holes drilled in ore mass from inclined drill raise with simultaneous delivery of ore by blast force to ore receiving workings and formation of magnetic field in room worked out space adjacent to roof. Vector of magnetic induction is horizontal in direction of ore delivery. Magnetic field is formed for the of performance of blasting operations in the room. Magnetic field is formed by electromagnets which are located on the conjugation of horizontal connections and room worked-out space. EFFECT: higher efficiency. 3 cl, 2 dwg
