Best Practices for Dust Control in Coal Mining [2010] [PDF]
"Respirable dust exposure has long been known to be a serious health threat to workers in many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers' pneumoconiosis (CWP).

CFD MODELLING OF THE DUST AND AIR VELOCITY BEHAVIOUR AT AN UNDERGROUND COAL MINE ROADWAY
Dust pollution for ventilation systems is a big problem for mine workers in underground coal mines. The respirable dust concentration is important to the physical and spiritual health of miners. It is hazardous up to 2 mg/m3in the air in underground coal

Study on airflow-coal dust dispersion pattern and control technology in fully mechanized mining face
The shearer in a fully mechanized mining face generates significant turbulent airflow during coal cutting, resulting in changes in airflow velocity in the mining area and causing the lateral dispersion of coal dust particles toward pavements.
