The risk of spontaneous combustion of coal is highly serious especially for underground coal mines. Coals react with oxygen immediately after producing in coal mines and they are subject to spontaneous combustion. This reaction is an exothermic reaction and coals give heat to the surrounding air.
Acid mine drainage can be defined as the overflow of acidic water from abandoned mines (Websters Dictionary). It can be a byproduct from mining practices used to extract coal, copper, gold, silver, zinc, lead, and uranium (Center for Educational Technologies).
What is coal? 9 February 2015 Most people know coal as a fossil fuel which is used to produce around 40 percent of the world's electricity. 1 It's a flammable black or brown sedimentary rock, and is made mostly of organic carbon.
