Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

Two prep plants were added (one active and one idle), seven ...
The waste slurry contains water, coal fines, silt, clay and other fine mineral particles from the processing plant. In most cases, the slurry is discarded into an impoundment (Fig. 19 ). An impoundment is an engineered structure consisting of a large volume earthen settling basin formed behind a manmade dam or embankment.

The uncovered coal is in turn then blasted to break up the layers and loaded into large trucks which can hold up to 300 tonnes of material. The coal is transported to the processing plant where impurities are removed. Coal that is deeper than a few hundred metres under the surface must be extracted using two underground mining methods.
