What is spontaneous combustion ? What is common cause of fire in coal mines
Answered by admin @
Answer:
Explanation:
Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating, followed by thermal runaway and finally, auto ignition.
Coal is associated with deposits of methane. When this methane gets exposed as a result of the digging, it gets mixed with air and forms an explosive mixture. A small spark can set off this mixture and cause explosions and fire. The burning methane can set off secondary fires when the coal dust inside the mine catches fire.
