This study was organized as part of a larger effort to identify technically and economically feasible controls for curtailing diesel particulate matter (DPM) and gaseous emissions from existing and new diesel-powered vehicles used in underground mines. The objective of the tests, performed in an underground mine using an isolated zone testing methodology, was to determine the effects of selected emission control technologies, including reformulated and alternative fuels, on the ambient concentrations of particulate matter and gases emitted by diesel-powered mining equipment. The results of several earlier studies showed the potential of reformulated diesel fuels, such as water-in-diesel fuel emulsions, biodiesel blends, and ultralow sulfur diesel, for controlling DPM emissions. This paper summarizes the results of the isolated zone tests and reports the effects of several selected reformulated fuels on the concentrations of nanometer and ultrafine particles, elemental carbon, and total particulate matter in mine air.
