ROSAIRE BUSHEY MECHANICAL ENGINEERING $900,000 Multi-disciplinary project aims to make mining more efficient For people who are involved with mining, there are two things that are paramount to an effective operation – efficiency, and safety, and the industry is always looking for ways to improve both. Researchers at Virginia Tech are leading a multi-disciplinary team in a three-year $900,000 project to improve the efficiency of dust scrubbers in underground mining operations. Funded by the Alpha Foundation for the Improvement of Mine Health and Safety, Aaron Noble, associate professor, mining and minerals engineering, is working with Shima Shahab, assistant professor of mechanical engineering, and Hassan Amini, a research scientist with mining and minerals engineer- ing, as well as collaborators from Michigan Tech, and Cornell University. “Underground mines make use of machines called continuous miners that shave off layers of coal or rock with a large cutting wheel at its front,” said Noble, the project’s primary investigator. “Scrubbers are a kind of dust filter integrated into the design of the cutter. As the machine advances it generates a lot of its own vibrational energy. Part of what we’re trying to do is to create a dust suppression system that harvests that vibrational energy to manipulate it in a way that is useful to the suppression effort.” Current dust collection systems require multiple work stoppages during the course of a day to replace and clean filters and hardware. The team will incorporate new materials that better collect dust, and use the continuous miner’s vibrations to help keep the filters from
