For example, Dogra et al. (2021) proposed a novel machine learning and Graham's ratio data integration approach to predict the likelihood of a mine fire in accordance with the environmental factors that cause coal to heat up by itself. This has been set up in order to account for the factors that cause coal to spontaneously catch fire.

Coal spontaneous combustion is one of the disasters occurring in underground coal mines. As a typical case, the spontaneous combustion of broken coal left in the longwall gobs often happen which could greatly interrupt the normal mining production. Such concealed thermal event is featured as rapid development and difficulty in locating "hot" spots. If such spontaneous combustion fails to ...

Coal readily reacts with oxygen and releases heat, the exothermic reaction can cause coal spontaneous combustion, which often triggered coal fire [1], [2], [3]. The key to the prevention and control of coal spontaneous combustion lies in early monitoring, and many scholars are devoted to coal spontaneous combustion monitoring research work.

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.
