24.11.2019· Dust control measures apply to any construction site where there is the potential for air and water pollution from dust traveling across the landscape or through the air. Dust control includes practices used to reduce or prevent the surface and air transport of dust during construction.

Most respirable dust particles are too small to see. Normally, the focus is placed on smaller dust particles (100 microns or less [.004"]) as they tend to stay airborne while larger, heavier particles usually settle out of the air. Suppression VS. Prevention. Suppression and prevention are commonly debated when it comes to dust control methods.

CMDLD also includes chronic bronchitis and emphysema, which were documented in coal mine workers in the 1940s. 24 While initially attributed to smoking alone, coal dust‐related obstructive chronic bronchitis (OCB), emphysema and accelerated lung function decline have since been amply confirmed. 25, 26 These effects are additive rather than attributable to smoking alone and can also occur

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). CWP is a lung disease that can be disabling and fatal in its most severe form.

The problems of dust emission are tackled either by dust extraction or suppression. In India, coal preparation plants don't employ thermal drying so the problems caused by dust are not as serious as in other countries. Even so, dust hazards are required to be controlled so that a cleaner and safer working atmosphere is maintained.

2.3 Coal dust Coal dust accumulates when small solid coal particles are suspended in air for some time before settling down. A wide range of particle sizes is produced during dust generation. Coal dust is produced during coal processing. The amount of coal dust produced is measured in microns. Coal dust particles ranges in diameter from 10µm
