Debilitating Lung Disease Among Surface Coal Miners With …
The Federal Coal Mine Health and Safety Act of 1969 (Coal Act) established the federal permissible exposure limit (PEL) of 2.0 mg/m 3 for respirable coal mine dust in underground and surface coal mines and mandated regular inspections of surface and underground mines, in an effort to prevent coal workers' pneumoconiosis.

The spirochetes which he described are less virulent than ours. On his advice we have carefully examined house and ditch rats in the city and rats in the coal mines of Kyushu, where Weil's disease prevails, and found that 39.5 per cent carried highly virulent pathogenic spirochetes in their kidneys, thus confirming Miyajima's experiments.

But if the rule is adopted, the agency predicts it would save only 63 coal miner lives and avoid 244 cases of black lung disease over 60 years. An investigation by Public Health Watch, NPR, Louisville Public Media and Mountain State Spotlight suggests this may be a gross underestimate of the rule's potential upside.
Negative Effects of Coal Mining

As coal miners suffer and die from severe black lung, a …
Mining machines cut through the rock to reach and to mine coal seams, grinding rock into fine, sharp and easily inhaled silica particles. Exposure to silica dust likely explains Smith's complicated black lung diagnosis at the relatively young age of 39 and after just 12 years of cutting rock and coal underground.
The Impact of Black Lung and a Methodology for Controlling …
Abstract. Coal workers' pneumoconiosis (CWP), commonly known as black lung, is caused by the inhalation of respirable coal mine dust and is a disabling and potentially fatal lung disease with no cure. Historically, CWP has taken a tremendous human and financial toll in the US coal mining industry. Recent health surveillance data indicates ...
Study: Severe black lung disease among Appalachian coal miners
A new study provides the first evidence of its kind that silica dust is responsible for the rising tide of severe black lung disease, including among coal miners in Appalachia. Exposure to a toxic ...
Health Problems from Mining
Mining damages health in many ways: Dust, chemical spills, harmful fumes, heavy metals and radiation can poison workers and cause life-long health problems as well as allergic reactions and other immediate problems. Heavy lifting and working with the body in awkward positions can lead to injuries to the arms, legs, and back.
