.hmc. ‘Wherever water is used for DUST SUPPRESSION in Mines / CHP / Power / Steel Cement / .hmc Conflow products can be found’ The main areas of use is :- 1. Dust Suppression

.hmc. Dust Suppression Why needed: airborne coal dust, when mixed with gas and in the presence of a naked flame, is very dangerous and causes an explosion. What is needed: methods of using the plentiful supply of water available in a coal mine to suppress the dust products to control, filter, measure and (most importantly) spray, water to supress the dust to prevent it becoming airborne Essential Dust Suppression Requirements: CONTROL - FILTER - SPRAY Where located: conveyor belt line transfer points roadway headings coal faces roof support systems
