The impacts of coal dust on miners' health: A review

Exposure of coal dusts can be prevented through administrative controls and engineering controls. Ineffective control of coal dust exposure can harm coal workers' health. Although many efforts have been made to eliminate these threats, recent years have seen an unexpected increase in coal workers' pneumoconiosis (CWP) in Appalachian basin in US

CDC Mining Silica Adds to Respirable Dust Concerns NIOSH

Most miners are fully aware that exposure to high concentrations of respirable dust and crystalline silica (hereafter simply silica) can affect their health and future life, and many miners with longer tenure have co-workers who suffer from lung diseases caused by dust present in mines. In coal mines, these lung diseases have very well-known

Research finds additional harm from coal dust exposure

Feb 20, 2013· For years, many miners who breathed in too much coal dust got sick and died of black lung disease. But coal dust can cause serious health problems above ground as well, according to studies by a public-health researcher presented in Boston Sunday at the annual conference of the American Association for the Advancement of Science.

Study Shows Surface Coal Miners Are Exposed To Toxic Dust

Dec 10, 2019· Appalachian surface coal miners are consistently overexposed to toxic silica dust, according to new research from the National Institute for Occupational Safety and Health, and surface mine dust contains more silica than does dust in underground coal mines.. The research is the first to specifically analyze long-term data on exposure to toxic silica dust for workers at surface mines.

Studying the health effects of underground coal dust

The US Mine Safety and Health Administration (MSHA) reduced the maximum allowable levels of dust in mines under the 2014 Respirable Coal Dust Rule. Under the law, the MSHA “sets forth a respirable dust standard that limits miners’ exposures to airborne respirable coal mine dust (RCMD) in underground coal mines to 1.5 mg/m 3 during the full

Study Shows Surface Coal Miners Are Exposed To Toxic Dust, Too

Dec 10, 2019· Silica dust comes from quartz in the rock layers near coal seams, and it is significantly more harmful to lung tissue than coal dust alone. “The exposure to coal mine dust declined over time

Coal dust Wikipedia

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
