outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is
Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
The Mining Process. Once a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining
Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.
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 that
Ask the students what is meant by reclamation. Reclamation refers to the process of restoring the land that was disturbed by a mining operation to create an environment that is safe and productive for use by future generations. Discuss the possible safety and environmental issues that could result if the mine site was not reclaimed.

Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

The Mining Process. The Mining Process. 1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Step 3 (Underground) GOING UNDERGROUND. Miners, mining materials and equipment are transported deep underground via the mine cage in the vertical shaft, which can go to depths of up to 3.5km below the surface. Open-pit gold mining also takes place in South Africa. This is a mining technique which excavates at the surface to extract ore.
SURFACE MINING PROCESS • Construct structures to control runoff and protect surface and ground water quality. • Remove topsoil from planned disturbance • Remove any remaining rock from coal seams as it is exposed. • Break up coal by ripping with a dozer or using explosives.
