Open-pit mine planning with operational constraints
Open-pit mines must be designed to develop the Earth’s natural resources in the most responsible, sustainable, and economic way. Traditional mine planning optimization methods do not consider operational constraints; such as minimum mining width or minimum pushback width constraints, and often do …

Applications of Queuing Theory for Open-Pit Truck/Shovel Haulage Systems
Surface mining is the most common mining method worldwide, and open pit mining accounts for more than 60% of all surface output. Haulage costs account for as much as 60% of the total operating cost for these types of mines, so it is desirable to maintain an efficient haulage system. As the size of …

A geological study of the River Ranch kimberlite pipe and associated diamonds and mantle minerals : Limpopo Mobile Belt, Zimbabwe
… pyroclastic rocks exposed in the diatreme during open pit mining operations. Six intrusive kimberlite phases have been recognised in the diatreme by careful mapping and confirmed by petrographic observations, particularly variations in groundmass mineralogy. Subsequent to emplacement, the diatreme …

Effects of Large-Scale Gold Mining on Habitat Use and Selection by a Resident Population of American Pronghorn
… resources in an area associated with a large open-pit gold mine. We classified levels of disturbance associated with the mine and used a random forest model to select ecological covariates associated with habitat use and selection by pronghorn. We used resource selection functions to examine …
