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.

Mechanical Advantage. Open pit mining offers an advantage over shaft mining in that it is mechanically simpler to do. Space is not restricted in open pit mining. Trucks and mining machinery are free to move around as they need to. More machines can move more ore and haul off waste rock more quickly. Because an open pit mine is …

The Chuquicamata mine in northern Chile's Atacama Desert is one of the deepest open-pit mines in the world, second only to Bingham Canyon in Utah. The extraction of huge stores of copper has hollowed out the landscape; the largest pit at the site reaches a depth of approximately 1,000 meters (3,300 feet). Evidence of mining …

This paper explored a convolutional neural network to assess the clustering of selective mining units (SMUs), generated by a genetic algorithm (GA) approach. The purpose of the GA was to optimize a set of dig limits in a mine bench. Dig limits are boundaries to separate/split SMUs as per waste and other processing categorizations so …

9.2 Open Pit Mines. At the end of an open pit operation, sump pumps and/or dewatering wells are decommissioned. The geometry of the pit and the void volume may be modified if partially backfilled with mine waste. Following cessation of pumping, in most climatic regimes, both surface water and groundwater will inflow to the pit, creating a pit ...
