Dust generation from mine haul roads Dust generation from unpaved mine roads is the process by which particulate matter becomes airborne. Such generation is termed a fugitive (or open) dust source. The amount of dust that will be emitted from an unpaved haul road is a function of two basic factors (ARRB, 1996): the erodibility of the wearing course
Air quality management: a mining perspective - WIT Press
Mine dust is often, incorrectly, considered to be chemically inert. However, the amount of fine dust, PM10 and 2.5, and the chemical and mineralogical composition of the dust generated by a mine will often ultimately dictate the potential for health impacts. The control of "nuisance" dust which is deposited in the vicinity of a mine is
