Abstract
Wind transport of particulate matter has been a significant issue for industries that handle bulk materials, such as coal and salt terminals, mining operations, pits and quarries. Both dust and larger particles can have adverse environmental effects and can be a nuisance to neighbors of these facilities. Over the past 25 years, the authors have studied this problem for a wide range of industrial facilities throughout North America. One of the key tools used in developing effective control measures has been scale-model simulations conducted in boundary-layer wind tunnels. This tool has provided a convenient means of replicating the complex wind conditions that occur around the stockpiles and structures at industrial plants and the testing of a range of solution options, such as windscreens, berms, surface stabilization techniques, etc. Case studies involving the use of this tool will be presented. The first case study involved scale-model simulations of a mine tailings disposal area to assess the effectiveness of windscreen arrangements. Full-scale laboratory wind tunnel tests were also performed to assess the effectiveness of rocks and straw tufts as surface treatments to reduce wind drag on the tailings surface. The second case study involved wind tunnel tests on a scale-model of a coal stockpile field at a steel mill to assess the effectiveness of a combination of berms and windscreens on reducing wind erosion of the stockpiles. The third case study involved initial wind tunnel tests to assist in designing a 25 m high windscreen for sawdust piles at a pulp and paper mill, and then retesting and re-examination of the problem 25 years later. These case studies highlight the benefits that have been derived from applying scale model wind simulations to the problem of fugitive dust emissions at industrial facilities.
