Reduced energy consumption and environmental impact, with IPCC systems, was already realized in the 1970's. With bulk material haulage limited to conventional open trough conveyors, this precluded the most direct path out of the open pit, requiring low angle spiral ramps and/or deep slots and/or tunnels through the pit high wall.

8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

E Contd. E. Pit design Overall slope of a pit depends on several factors of the pit slope: a) Geological disturbances like faults etc. b) Hydrological condition of strata c) Orientation of slip planes d) Nature of strata – i.e. hardness, material consolidation etc. e) Depth of workings f) Design of haul roads & ramps in the highwall g ...

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Mining Conveyors Make Transitions. October 2020 | Features. A construction photo shows the transfer building where Chuquicamata's 11,000-mt/h conveyor system, which travels a 6.4-km ramp from the underground ore storage bins, discharges on to another conveyor that transports the ore to a processing facility 5 km away.
