Coal Dust Monitoring
Respirable coal dust exposure assessment in mining and handling operations
What Is Coal Dust Monitoring?
Coal dust monitoring measures respirable dust exposure in coal mining, handling, and processing operations. Coal workers' pneumoconiosis (CWP or black lung) re-emerged in Queensland in 2015, prompting a national review of coal mine dust monitoring practices and regulatory enforcement.
Safe Work Australia amended the WES list in October 2022 to reduce the WES for coal dust (containing less than 5% quartz) from 3 mg/m³ to 1.5 mg/m³ (respirable fraction, TWA-8h), and the WEL list keeps it at 1.5 mg/m³. Monitoring must also assess the respirable crystalline silica component, as many coal seams contain quartz-bearing strata.
How Is It Done?
Personal sampling via cyclone and pre-weighed filter cassette. Gravimetric analysis for total respirable dust. Silica speciation by XRD (NIOSH 7500).
