Spontaneous heating and fire in coal mines is a major problem worldwide and has been a great concern both for the industry and researchers in this field. Majority of fires existing today in different coalfields are mainly due to spontaneous combustion of coal. The auto oxidation of coal ultimately leads to spontaneous combustion which is the major root cause for the disastrous of coal mine in leading

Assessing and managing spontaneous combustion of coal

combustion is still an important safety issue within the coal industry (World Coal, 2015) . Most underground mine explosions are due to a build-up of methane which is then ignited by a spark, usually from a piece of equipment or a friction event.

Spontaneous Combustion Description underground COAL

Strictly speaking, it is the oxidation process that is combustion and, to the extent that all coals oxidize, all coals are prone to spontaneous combustion. However in coal mines, coals spoken of as being liable to spontaneous combustion are those coals which will develop to an open fire under specific conditions. Many seams will not reach this point.
