The problems ofdustemission are tackled either bydustextraction or suppression. In India,coalpreparation plants don’t employ thermal drying so the problems caused bydustare not as serious as in other countries. Even so,dusthazards are required to be controlled so that a cleaner and safer working atmosphere is maintained.

Dec 09, 2011· There are two main types of coalmineexplosions: methane andcoal dust. Methaneexplosionsoccur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below itsexplosionpoint. Likewise, fine particles ofcoal dustin the right concentration that contact a source of heat can also be explosive.

Millexplosionswill only occur when three conditions exist: sufficient oxygen (≥12 per cent O 2-in-air), the presence of an ignition source (>30mJ) and air-suspendedcoal dustin a bandwidth of 50-2000g/m 3. Safe operation ofcoalmills seeks to avoid these conditions and many monitoring systems exist to provide fire andexplosionprotection.
