Protecting against airborne dust exposure in coal mines

inhalation of coal dust and is commonly referred to as black lung disease. The disease gets its name because affected lungs appear to be black in colour rather than pink. CWP is caused by prolonged exposure to respirable coal dust and the gradual build-up of coal dust particles within the terminal airways. Your body reacts to these particles

Current Review of Pneumoconiosis Among US Coal Miners

The impact of dust from a nearby mine on local amenity depends on the distance from the mine site and climatic conditions such as wind. Concerns about amenity from mine site dust often relate to visibility of dust plumes and dust sources. Visible dust is usually due to short-term episodes of high emissions, such as from blasting.
