2013-3-14 These methods and equipment also can provide increased efficiency relative to room and pillar or shortwall mining techniques. In one aspect, methods for use in a mining operation include: advancing a continuous miner towards an angled face that extends from a headgate to a tailgate; performing an angled cutting turn in which the continuous miner turns less than 90°; advancing the continuous miner

Mining Methods and Equipment. The majority of open pit mines in Australia currently operate using discontinuous shovel/truck systems. These systems are favoured as they enable; (i) mining capacity to be progressively scaled up over the life of a mine; (ii) the use of narrow benches that defer the high costs of stripping, and (iii) flexibility ...

2019-12-4 Most forms of surface mining use heavy equipment such as earthmovers to remove the overburden before bucket wheel excavators or dragline excavators extract the mineral. Surface mining is done in five ways: Strip mining – Strip mining is the most common surface mining method used to mine coal and lignite. The process is done by removing a strip of overburden before mining a seam of mineral.

2021-1-12 There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.
