Coal is extracted from the earth through underground mining or surface mining. The choice of mining method is largely determined by the geology of the coal deposit and its distance to the surface. Underground mining currently accounts for a larger share of world coal production than surface mining.
Coal has three primary advantages compared to other fuel sources, both non-renewable and renewable: abundance, affordability and low capital expense needed to build coal-powered generation plants. Coal deposits can be found in over 70 countries around the world, with estimates on global reserves of just under 1 trillion tons.
Coal is South Africa''s major primary energy source, and plays a significant role in supplying the chemicals and steelmaking industries. The benefits of coal production are relevant in the light of South Africa''s development priorities of job creation and economic growth.
Mine safety is one of the major benefits of the Internet accessible digital mine maps. These maps provide easily accessible reference to past and current mining activities. They provide a tool to determine adjacent mining in the same seam as well as mining in seams above and below the seam where mining is actually taking place.
Jan 16, 2013· - Coal is the least expensive fossil fuel because it is rather simple to mine - Coal powered generation scales well, which makes it possible to build a variety of sizes of generation plants -Since coal is a fossil fuel, it can be used to build power stations almost anywhere as long as there are
The people own the coal. Issuing resource titles that allow Adani to proceed with a vast coal mine -- in defiance of the social, economic and environmental impacts of such a project within a carbon-constrained economy -- arguably represents a dereliction of the state''s duty to act in the public interest.
