Surface mining - Wikipedia Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the ...
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and ...
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations …
Underground coal gasification - Wikipedia. Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an in-situ gasification process carried out in non-mined coal seams using injection of oxidants, and bringing the product gas to surface through production wells drilled from the surface.

Sunrise Coal, Indiana's second largest coal producer, is focused on safely and efficiently mining high-quality bituminous coal from the Illinois Basin. Our current operations include: Carlisle Mine, Indiana – Sunrise's flagship underground mine with 65 million tons in coal reserves.
The room-and-pillar mining method is used in all of Pennsylvania's underground bituminous coal mines including longwall mining operations, where it is used to develop the haulage and ventilation systems, and to delineate and support the longwall panels.
Some operations have very thin seams of coal that are not practical to recover using conventional methods. We can extract these seams with surface miners, lowering the strip ratio. Aggregate Operations.

Coal production is a major contributor to global warming: burning coal generates large quantities of carbon dioxide and mining operations can release methane, a known greenhouse gas, into the atmosphere. The coal mining industry is working to improve its public image.
The operation utilises opencast strip mining methods to mine the remnant coal pillars that was a result of the underground extraction mining methods practiced in the area in the 1960's. The mine currently produces at a rate of 17Mtpa and aims to continue the supply to Eskom's Lethabo Power Station from additional coal resources until 2039.
