extraction methods. OPEN PIT MINING Open Pit Mining Open pit mines involve digging large open holes in the ground as opposed to a small shaft in hard rock mining. This method of mining is most often used with minerals like copper and molybdenum Open pit coal mining has been popular in Europe, but is used on a more limited

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which ...

Surface mining is often preferred to subsurface mining by companies in the industry because it is less expensive, there are fewer complications with electricity and water, and it is safer. However, surface mining can be more environmentally-damaging than subsurface mining. Types of Surface Mining Open-Pit Mining

Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow..
