SURFACE MINING ≠ STRIP MINING: Although sometimes mistakenly referred to as strip mining, oil sands is actually mined from an openpit below several meters of mining is the mining of a relatively flat deposit very close to the surface, commonly used in coal or phosphate industries.
The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining.

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.
Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from .
Mining. The workings comprise an openpit mine, an underground mine and four concentrators. The openpit mine, which forms a milewide crater at the surface, is a highvolume lowcost operation, producing more than 67 million tonnes of ore and providing more than 75% of the mill feed in 2006.
Openpit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts. In general, openpit mining consists of a system to exploit open pits with multiple benches.
