increased miners' risk of developing lung disease.
One of the study was conducted to investigate the potential harmful element (PHE) concentrations in coal dust
and evaluate the human risk assessment and health effects near coal mining areas.
The CP material used the coal dust
, which was generated from the underground drilling construction as filler, and was supplemented by amino resin as binder, and added some other additives, such as cross-linking, foaming, toughening, and coupling agents.
When a miner is injured, coal dust

is known to cause a range of health problem primarily respiratory and cardiovascular illnesses too," said Aishwarya Mabimeni, coal campaigner of Greenpeace.
The concentration of coal dust
(Carbon and Quartz) was 4-5mg/m3 and 0.35mg/m3 respectively as against the threshold limits of 2mg/m3 and 0.05-0.1 mg/m3 for 8 hours daily and 40 hours/week.
