A method of mining that employs large equipment to remove the overburden (rock, dirt, etc.) thereby exposing the coal seam. Includes methods such as mountain-top removal, contour strip, area (or strip) mining and auger mining.
type of coal mining (also called strip mining) in which layers of land are removed, leaving an open "pit."
The mining in surface excavations. It includes placer mining, mining in open glory-hole or milling pits, mining and removing ore from open cuts by hand or with mechanical excavation and transportation equipment, and the removal of capping or overburden to uncover the ores. Mining at or near the surface. This type of mining is generally done where the overburden can be removed without too much expense. Also called strip mining, placer mining, opencast mining, opencut mining, or open-pit mining.
All or any part of the process followed in the production of minerals from a natural mineral deposit by the open pit or open cut method, auger method, highwall mining method which requires a new cut or removal of overburden, or any other mining process in which the strata or overburden is removed or displaced in order to recover the mineral or in which the surface soil is disturbed or removed for the purpose of determining the location, quality or quantity of a natural mineral deposit. TCA § 59-8-202
Some minerals are also mined from surface pits. See strip mining.
Technique used to remove all material exposing the desired ore deposit.
(2) the mining in surface excavations, including placer mining, open pit mining mining, removing ore from open cuts by hand or with mechanical excavating and transportation equipment, and the removal of overburden to uncover the ore.
A mine in which the coal lies near the surface and can be extracted by removing the covering layers of rock and soil.
Process of removing soil and rock to expose and remove coal
Removing soil, subsoil, and other strata and then extracting a mineral deposit found fairly close to the earth's surface. See area strip mining, contour strip mining, mountaintop removal, open-pit mining. Compare subsurface mining.
Surface mining is a type of mining used to extract mineral deposits that are close to the surface.
