Researchers from University of Utah Report Details of New Studies and Findings in the Area of Mining and Metallurgy (Development of a Real-time Respirable Coal Dust and Silica Dust Monitoring Instrument Based On Photoacoustic Spectroscopy)

摘要

2022 SEP 15 (NewsRx) – By a News Reporter-Staff News Editor at Mining & Minerals Daily Daily – Investigators publish new report on Mining and Metallurgy. According to news reporting originating from Salt Lake City, Utah, by NewsRx correspondents, research stated, “We report the first spectral photoacoustic measurements of silica, coal, and kaolinite dust absorption coefficients from 11 to 13 mu m at 5 nm resolution made with a tunable quantum cascade laser. This is important because airborne silica dust and coal dust within mining environments continue to be a problem for mine workers and staff due to their severe health effects on the respiratory system, while other dust types are potentially interferents to their detection.”
