METHOD OF OPTIMIZING CYCLIC AND CONTINUOUS TECHNOLOGY COMPLEXES LOCATION DURING FINALIZATION OF MINING DEEP ORE OPEN PIT MINES
Abstract
A dynamic method has been developed for optimizing reload horizon of a cyclic and continuous technology complex (CCTC) with a combined road-conveyor-rail type of transport for round open pit fields, providing a rational depth of rail transport installation together with economically viable horizons for the location of the concentration horizon and reload from steeply inclined conveyors into the inner mine railway transport. Mining in border and deep zones of open pit mines is conducted in constrained conditions. Compact high-production mechanism for loading from dump trucks to conveyors and from conveyors to railway transport is developed to decrease dimensions of loading areas. Considerable difficulties arise in constructing rail stations on round open pit fields for exchanging trains on periodically moving open pit walls and organizing their movement with dead-end turns in contrast to elongated open pit fields. The field of application of railway transport usually extends to the zone of formation of temporarily non mining pit sides and on open pit mines of Kazakhstan does not exceed 150-170 m.
