COMPARING THE AIR QUALITY INSIDE ENCLOSED CABS OF UNDERGROUND MINING EQUIPMENT WITH MERV 16 AND HEPA FILTERS

COMPARING THE AIR QUALITY INSIDE ENCLOSED CABS OF UNDERGROUND MINING EQUIPMENT WITH MERV 16 AND HEPA FILTERS
This paper by a team of four NIOSH technologists explores their analysis over a four year period comparing the quality of air inside vehicle cabins with either a HEPA (high efficiency particulate air) vs a MERV 16 (minimum efficiency reporting value) filter deployed.  Two machines operating in similar environments at the one site were compared

Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 2004

The National Institute for Occupational Safety and Health conducted a study in 2004 to determine the effects of selected, state-of-the-art emission control technologies on the ambient concentrations of particulate matter and gases emitted by underground diesel-powered mining equipment. Tests were conducted in an isolated zone of an underground mine to evaluate the effectiveness of alternative fuel formulations, namely, water-fuel emulsions, blended biodiesel fuels, ultralow sulfur diesel fuel, and #1 diesel; and selected exhaust aftertreatment devices.
