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

FIELD: mining. SUBSTANCE: method for mining of inclined ore bodies includes drilling of blast holes on the side of worked out adjacent panel up to crossing the side face of panel which is supported through the extraction thickness of re body with barren rocks, broken and delivered by the force of blast. Heap of broken barren rock is packed by cementing mortar which is supplied through holes adjacent to heap of panel side face. Besides, barren rocks are broken by layer oriented to the dip of the worked out panel and delivered along the strike of ore body, and inclined raise is driven in underlying rocks under broken mass of barren rocks and drill drift is formed from the upper end of inclined rake and located at the level of foot of worked out space of worked out panel. From the drill drift, vertical hole rings are drilled for blast breakage of barren rocks. EFFECT: higher efficiency. 3 cl, 3 dwg
