Abstract.
Thearticle focuses on possibility of maximal iron ore extraction and transportation from the deep open-pits horizons with minimal stripping operations.
Current situation in the existing deep open-pits is analyzed in the paper, basing on which priority areas of the open-pit mining operation expansion are determined with possible mining up to the total depth of the pit. Taking into consideration falling prices for iron ore, high cost of concentrate produced by the domestic MPPs could be cut by reducing volumes of dormant balance reserves of iron ore bedded under the transport communications, concentration horizons of the CFT complexes and transshipment points.
A technological scheme was designed in order to extract ore reserves within the open-pit bottom with lower cost of stripping operations and to increase resultant angel of the highwall slope.
Methods for extracted reserves transporting from the deep horizons to the surface by the shortest rout are analyzed for cases when the skip hoist systems and conveyor transport are used and with taking into account increasing angel of the highwall slope in the pit.
Keywords:
cost of ore production, dormant reserves, transport communications, concentration horizon, mining of the deep horizons.
