Commercial coal mining: Good news for

Therefore, even if the actual cost of production comes down due to commercial mining, the net landed cost of coal at the consumer end is unlikely to be impacted too much. From a distribution company's point of view, it will prefer to source power from producers with the lowest generation tariff and is very unlikely to go any lower as a result of commercial mining.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
