Jul 15, 2019 Coal is a natural, complex structural energy material. During the process of combustion or explosion, coal powder undergoes devolatilization, volatile gas combustion, fixed carbon combustion, ash melting, and ultimately forms non-combustible residues. The physical and the chemical characteristics of the coal powder changes greatly.

Dec 09, 2011 There are two main types of coalmine explosions: methane and coal dust. Methane explosions occur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below its explosion point. Likewise, fine particles of coal dust in the right concentration that contact a source of heat can also be explosive.
