From the SRUs, the exhaust is directed to the HEPA filter banks located within the New Filter Building. The exhaust system is designed to provide steady HEPA filtration prior to release to the exhaust stack. There are 22 HEPA filter banks rated at 27,000 CFM / 12.75 msup 3/s every. Each filter financial institution has two phases of pre-filters and two stages of HEPA filters. The filtered air from each of the 22 filter banks discharges into a typical concrete plenum, which is maintained under a negative strain by the primary exhaust followers. Six 1,000 HP variable frequency drive exhaust followers are supplied on the south facet of the plenum. At the utmost expected exhaust move of 540,000 CFM, 4 exhaust followers and twenty filter banks will be in operation.

Natural mine ventilation is the process of supplying fresh air with out utilizing any mechanical systems. The exterior air strikes into an enclose space due to stress differences arising from pure forces. Natural mine ventilation distributes oxygen from contemporary air which boosts pulmonary and coronary heart operate. Mechanical ventilation is used to supply air in areas the place the miner operates, and this air is used to take away mud particles, noxious gases and regulation of temperature. Pressure difference is created by operating a number of mine air flow followers in an airway.
