Guidelines for dust control in small underground coal

Abstract. The Bureau of Mines handbook presents guidelines for controlling dust in underground room-and-pillar coal mines. The dust-control techniques presented are primarily directed toward cost-effectiveness for the operators of small mines facing tightened Federal regulations due to excessive respirable quartz dust.

As indicated by data on disease prevalence and severity, workers in smaller mines may be at special risk. 7.

Overexposure to coal dust can lead to coal workers' pneumoconiosis (CWP) or ‘black lung disease’, which can be fatal. We have developed better technologies and strategies to reduce coal-mine workers’ exposure to dust which are being used in many mines today.

Working in the Coal Mine Avoiding Dust Inhalation

2014-12-9  Dust inhalation is a huge concern in coal, metal, nonmetal, stone, and sand and gravel mining operations. In fact, the U.S. Mine Safety and Health Administration (MSHA) considers respirable coal dust to be one of the most serious occupational hazards in the mining industry.

Coal Mine Dust Lung Disease. New Lessons from an Old

2013-1-8  Coal mining remains a sizable industry, with millions of working and retired coal miners worldwide. This article provides an update on recent advances in the understanding of respiratory health issues in coal miners and focuses on the spectrum of disease caused by inhalation of coal mine dust, termed coal mine dust lung disease.

Coal dust emissions Environment, land and water

Coal dust. Coal dust generally comprises a small component of total dust present in air near coal mines, railways and coal export terminals. Nevertheless, coal dust emissions can affect amenity, and predominantly comprises coarse dust particles (dustfall) of particle size generally between 50 and 200 microns in diameter.

There was inconsistent evidence of an association with coal mining, but no conclusive evidence of a dose-response relationship with respirable, or inhalable coal dust. Although it is biologically plausible that coal dust exposure could result in gastric cancer, the relationship could be explained

Black lung is back: why more is needed to fight mining dust

“The average quartz concentration for designated occupations in underground coal mines, those miners with the highest exposure to respirable dust, has declined dramatically. “In 2019, MSHA reported an average concentration of 24.6mg/m 3,the lowest in the history of sampling and well below OSHA’s standard of 50mg/m 3 .”

Best Practices for Dust Suppression in Underground Coal

2020-7-2  Coal dust buildup is often a root cause of premature maintenance and failure of mining equipment. To this end, preventative suppression is critical. Dust suppression methods. There are a variety of ways to suppress dust in coal mines that offer a varying degree of effectiveness and efficiency. The most common methods are: Bag filter system; Dry

Effects of occupational exposure to dust on chest

2019-9-5  The years of dust exposure were based on the time they worked in the dust exposure sites. According to the production capacity, coal mines are divided into three categories: large mines (more than 1.2 million tons a year), medium mines (0.3–1.2 million tons a year) and small mines (below 0.3 million tons a year). Blood pressure examination

Dust can be produced by almost all mining operations in underground coal mines and seen all around the mine. Different occupational groups get exposed to different dust levels and in order to minimize the probability of developing coal workers' pneumoconiosis (CWP), it is necessary to investigate the workers exposed to dust. This study aimed to evaluate the dust concentration conditions in
