Characteristics of Fugitive Dust Generated from Unpaved Mine Haulage Roads
Fugitive dust is generated along unpaved mine roads from intermitlent equipment traffic. Typically. the majority of such traffic consists of trucks hauling either mine product or waste from the surface mine pit andlor the processing plant. Fugitive dust generated along these unpaved mine roads includes particles of all sizes which become airborne. The potential hazards include the deleterious e...
متن کاملLong-Term Efficiencies of Dust Suppressants to Reduce PM10 Emissions from Unpaved Roads.
A 14-month study was undertaken to assess the long-term efficiencies of four dust suppressants (i.e., biocatalyst stabilizer, polymer emulsion, petroleum emulsion with polymer, and nonhazardous crude-oil-containing materials) to reduce the emission of PM10 from public unpaved roads. PM10 emission rates were calculated for each test section and for an untreated section for comparison purposes. E...
متن کاملEffect of vehicle characteristics on unpaved road dust emissions
This paper presents PM10 fugitive dust emission factors for a range of vehicles types and examines the influence of vehicle and wake characteristics on the strength of emissions from an unpaved road. Vertical profile measurements of mass concentration of the passing plumes were carried out using a series of 3 instrumented towers. PM10 emission fluxes at each tower were calculated from knowledge...
متن کاملNumerical validation of a near-field fugitive dust model for vehicles moving on unpaved surfaces
This paper presents a numerical model for evaluating fugitive dust emission and transport at near-field induced by a moving vehicle. The dust emission model describes the quantity and location of emitted dust. The transport of the dust is captured by the Lagrangian particle tracking method, and turbulence dispersion of particles is modeled stochastically. The presented model is validated ∗corre...
متن کاملSub-pixel Unpaved Roads Detection in Landsat Images
Unpaved roads are one of the most relevant causes of erosion process in rural regions. Locating unpaved roads in low-resolution satellite images is not a trivial task. Although they have the spectral response of bare soil, their spatial width is often far below the pixel size. Therefore, the pixels crossed by unpaved roads have a different spectral response over the scene depending on the surro...
