The risk of silicosis in mining has been well documented and various means of dust controls implemented. The basis of many of these controls remains the use of water to either suppress airborne dust or prevent dust from becoming airborne. One of the more difficult areas to contain dust is within the stope area. Most mines recommend watering down at the start of and during the shift. In this study use of a stope atomiser spray on worker exposure levels was investigated. The average reduction in the TWA quartz concentration across all occupations was calculated to be 79.2%.
