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 کاملEvaluation of dust exposure to truck drivers following the lead haul truck
Haul trucks have the potential to generate large amounts of respirable dust. This respirable dust has been shown to be a health hazard to personnel, especially if it has a high silica content. Lack of dust sampling data from haul trucks prompted the completion of a study to quantify respirable dust concentrations. These field studies were conducted measuring instantaneous respirable dust at sta...
متن کاملTrends in spatial patterns of heavy metal deposition on national park service lands along the Red Dog Mine haul road, Alaska, 2001–2006
Spatial patterns of Zn, Pb and Cd deposition in Cape Krusenstern National Monument (CAKR), Alaska, adjacent to the Red Dog Mine haul road, were characterized in 2001 and 2006 using Hylocomium moss tissue as a biomonitor. Elevated concentrations of Cd, Pb, and Zn in moss tissue decreased logarithmically away from the haul road and the marine port. The metals concentrations in the two years were ...
متن کاملA new developed model to determine waste dump site selection in open pit mines: An approach to minimize haul road construction cost
Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...
متن کاملImpact of Fugitive Dust Emission from Bauxite Crushing Industry on Soil Contamination (Case Study: Jajarm Alumina Factory)
Introduction: The origination of dust is often due to the wind erosion process. However dust emissions are sometimes the result of industrial activity during the production process, which is called industrial dust. One of these industries is rock crushing whose raw material is transferred from the mines to the factory. During the process of crushing, smaller pieces are eventually converted. The...
