Overburden Removal Coal Mining

Overburden Removal Samindo

Overburden removal is an activity that absolutely must be done on mining, especially in mining activities that use open-pit mining system. Overburden removal activity is determined by the target in the production plan; the better the design in the stripping of overburden will give the better production plan targets.

Overburden - Wikipedia

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overbu

Alberta UCP’s coal mining about-face: 9 things that haven’t changed

2021-02-12  Mountaintop-removal mining is a form of surface mining, which also includes open-pit or strip mining. Surface mining involves removing layers of soil and rock — referred to as overburden — to access minerals below. In some cases, the overburden is a mountain, in which case it’s called mountain-top removal mining.

In coal mining: Shovels and trucks Overburden removal is the most important operation in the system. When the haul distances are small (for example, 500 to 1,000 metres) and the overburden material soft, a fleet of scrapers can load, haul, and dump the overburden. Where distances are very small (for example,

Coal mining and selenium - Werner Antweiler

Open-pit and surface mining of coal produces large amounts of waste rock—also known as overburden. Runoff from this waste rock can release large amounts of selenium that eventually reaches rivers and lakes. Selenium tends to concentrate with the sulfur-containing minerals. Once exposed to air, it tends to oxidize into selenite or selenate.
