Question

Most of the explosions in mines occur due to the mixing of

Answer 1

There are two main types of coal mine explosions: methane explosions and coal dust explosions.

Methane explosions occur in mines when a buildup of methane gas, a byproduct of coal, comes into contact with a heat source, and there is not enough air to dilute the gas to levels below its explosion point,

Dust explosion needs a very high concentration of dust suspended in the air, which is very hard to find in a mine environment

Answer 2

Mine explosions can also be triggered when fine particles of coal dust come into contact with a source of heat. While methane is easier to ignite, the explosion pressure and heat value of methane is not as high as coal dust. In most cases, dust explosions are first caused by methane explosions,
