WIRTGEN surface miners cut primary resources such as coal, gypsum, iron ore, salt, phosphate, bauxite, limestone or granite, achieving high degrees of purity in the process. They are increasingly used as primary extraction equipment also in newly opened-up opencast mines or extensions of existing opencast mine operations.
Surface Mining Information System Main Content The Kentucky Surface Mining Information System (SMIS) is an extensive computer database that is used for tracking all permitting and enforcement actions on coal mining activity in the Commonwealth of Kentucky.
The surface mining equipment segment accounted for a revenue share of over 40% in 2017 and is anticipated to grow further during the forecast period. Currently, almost all metallic and non-metallic minerals along with a larger fraction of coal are mined via surface mining methods, which is expected to provide an impetus to the segment growth.

Change in production and productivity of US coal mines The higher productivity for open pit mining equipment also lowers costs.
Auger mining—A method of mining coal at a cliff or highwall by drilling holes into an exposed coal seam from the highwall and transporting the coal along an auger bit to the surface. Best technology currently available—Equipment, devices, systems, methods or techniques which will:
Coal Mining and Processing. Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our ...

A new variation of open-cut mining, high wall mining is not strictly a surface process, but instead a combination of surface and sub-surface mining. The process is also predominantly a coal mining technique, which has been employed successfully in Kentucky and West ia in the United States, and also in Queensland, Australia.
The choice of which mining method to use at many large surface coal mines is often dicated by what machinery is available or what experience the mine management can offer. One of the most significant surface coal mines in Turkey is owned and operated by the Turkish National Coal Board, located to the west of the city of Kütahya.
Surface mining activity includes the extraction of coal directly from the ground or from waste or stock piles, pits or banks. A permit is required to conduct surface mining activities. Permit area includes mining and support areas, facilities and roads. Permits are also required for exploration activities and processing plants. A coal mining ...
In India, the coal mining method mainly is the opencast one. Coal crusher machine and grinding mill are the necessary machines used in opencast coal mining production line. Here will introduce the detailed coal mining processing plant equipment for you all.
This handbook on surface strip coal mining serves as a general introduction to the subject of mining, specifically surface strip coal mining. It is intended as handbook for engineers who are new to the field of mining engineering, or for students who are entering the field with little prior knowledge.
Recommendation: There should be renewed support for advanced coal mining and processing research and development to optimize use of the nation's coal resources by increasing the amount of coal that is economically minable through technological advances …
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 mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
Coal mines require substantial capital investment in both permanent structures and depreciable mining equipment, exceeding $75 per annual ton of capacity in large underground coal mines and $30 or more per annual ton for large surface coal mines.
SURFACE MINING OF COAL by John Richard Schrock. WHAT IS SURFACE MINING? Surface mining is an efficient method for mining some minerals, especially coal, from deposits near the surface. It uses very large equipment to strip away overlying material, extract the coal, and then fill in the mined valleys.
Illustration of Typical Appalachian Coal Seam Showing Non-Coal Impurities Within the Coal In surface mining extraction, these non-coal impurities can be separated "in the pit" or separated from the coal by the surface mining equipment, negating the need for a separate coal processing plant.
Surface mining is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited - 90% or more of the coal can be recovered.
Common Equipment Used in Surface Mining. There's a specialized and diverse set of equipment commonly used during the surface mining process. If you're going to work at a surface mine, it helps to know the names of the following equipment and what they're used for.

Surface mining is an efficient method for mining some minerals, especially coal, from deposits near the surface. It uses very large equipment to strip away overlying material, extract the coal, and then fill in the mined valleys.
Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues. Once coal removal is complete, final regrading takes place and the area is revegetated.
