Open-pit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.
Mar 13, 2018· Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining is the preferred ...
Open pit mining is widely used in large orebodies at shallow depth or that outcrop on surface. 1 The depth of open pit mines is restricted by the stripping ratio. When the open pit mine reaches its designed ultimate depth, with ore remaining below this limit, the mine often evolves from open pit to underground mining. ... (Mining step 8), the ...

Mar 14, 2014· The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.
Mining - Mining - Surface mining: It has been estimated that more than two-thirds of the world''s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.
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, the extracting of ore, can be broken down into a three step process with diamonds. The first step is to extract the ore and two different practices are common in North America. In Colorado at the State Line Kimberlite District, open pit mining is the best choice for extracting the kimberlite ore.
When ore is located more than 100 metres below the surface, underground mining methods are more economical than mining by open pit. The first step in underground mining is to access the ore. First, miners dig vertical shafts to the depth of the ore, then cut a number of tunnels around the deposit.
