Abstract
This invention relates to novel configurations of open pit mines and methods of mining in open pit operations in which the benches are established radially outward from a turning point to facilitate the use of a mobile crusher adjacent the benches in combination with a belt conveyor system that can carry crushed mined mineral materials directly from the mobile crusher and deliver them directly to the turning point area.
Claims10
An open pit mine for the extraction of mineral materials from the earth's crust comprising:
- a turning point area having a substantially horizontally level floor adapted to facilitate the operation of material-handling equipment and to receive crushed mined mineral material;
- at least one bench moving on a downwardly sloping screw-shaped path extending radially outward from the turning point area;
- a mobile crusher for crushing mined mineral materials located adjacent the bench;
- a belt conveyor system for conveying crushed mined mineral materials from the crusher to the turning point area;
- and
- means for discharging the crushed mined mineral materials downwardly from the turning point area.
