Open Pit Mining - an overview ScienceDirect Topics

The characteristic that distinguishes open pit mining is the thickness of the coal seam insofar as it is virtually impossible to backfill the immediate mined out area with the original overburden when extremely thick seams of coal are involved.

Open-pit mining - Wikipedia

Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of co

Basics of an open pit mine - Mine Engineer.Com

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.

The Thin Coal Seam (TCS) Mining Technology for Open Pit ...

22.05.2018  During the open pit coal mining process, coal-bearing debris and the fragmented coal from the un-recovered TCS are poured into the waste-dump inside or outside the mining pits. The accumulated coal-bearing debris will be spontaneously combusted after reaching certain temperature and other combustion conditions (Xingming et al. 2001). Spontaneous

Open-Pit Mining Methods

09.04.2017  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. The stripping-pit limits must be extended beyond the limits of the ore pit to
