  • The Science of Coal Dust Suppression parker

    Airborne coal dust underground, if not dealt with preventatively, can be dealt with correctively once again using sprays. The principle here is that the dust agglomerates with the water, causing it to fall under gravity. However, it is not just a question of providing a water spray. If the water droplets are too large in size, then the airborne
