Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity.
What is the process of mountaintop removal coal mining? CLEARING. Before mining can begin, all topsoil and vegetation must be removed. Because coal companies frequently are responding to short-term fluctuations in the price of coal, the trees are often not used commercially, but instead are burned or sometimes illegally dumped into valleys.
Over 7269 million tonnes (Mt) of hard coal are currently produced worldwide and 787 Mt of lignite. Coal is mined by two methods: surface or 'opencast' mining, and underground mining.
The flow of coal mining process on underground mine. Wall mining. Coal conveying. Coal lifting. Stockpiling processing, hauling. Loading and marketing.
Coal mining Contribution to environmentally-friendly energy production. Coal preparation is essential and significant in providing clean coal for society and utilizing our resources efficiently.
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 begins.
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.
