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.

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.
Nowadays and in the near foreseeable future the quarry road transport will be the most common in the open-cut mining method. This is due to a range of advantages of open-pit dump trucks usage as compared with other types of quarry transport, i.e. autonomy, the possibility of using in any mining engineering and climatic conditions etc.
LOADING-HAULAGE EQUIPMENT SELECTION IN OPEN PIT MINES BASED ON FUZZY-TOPSIS METHOD. Key words Fuzzy method, open pit mine, haulage, machines and equipment Abstract Equipment selection in mining engineering is one of the most important decision that is affected the mine design, production planning and economic parameters in open pit mining.
open-pit mines. Alarie and Gamache (2002) studied the overview of solution strategies used in truck dispatching systems for open pit mines. Nenonen et al. (1981) used the interactive computer model for truck/shovel operations in an open pit mine; Ramani (1990) studied the haulage system simulation analysis in surface mining. Barnes et. al.
Optimal equipment selection is essential for efficient mining. Deswik deliver equipment selection scenarios that model the entire process. We implement the planning detail needed to understand all interactions and ensure that selection of any single-point solution does not create or transfer bottlenecks up or down the value chain.
