Monitoring and Sampling Approaches to Assess Underground Coal Mine …
Forms of coal range from soft (lignite) to hard coals (bituminous and anthracite) with higher carbon content. Anthracite, historically mined in Pennsylvania, has the highest carbon content (86 to 97 percent) and now accounts for only around 8 percent of coal production in the United States and 0.04 percent of the nation's underground mining (EIA, 2017a,b).

Figure 1 shows an example of a buildup and explosion of toxic gases, such as methane (CH 4), nitrogen dioxide (NO 2), and hydrogen sulphide (H 2 S) in an underground mine. The inhalation of an overlooked black damp in mines, which is a mixture of dust, carbon dioxide, and nitrogen [], gradually overcomes and destroys the …

The subject began underground coal mining at age 25 years in 1980. Surveillance radiograph showed category 1/1 pneumoconiosis at age 33 years (1988) and massive fibrosis at age 46 years (2001). ... Thus, reliance on protective masks to prevent chronic lung disease from coal mining is neither practical nor legal.

The Horses in the Coal Mines article reports that, in the early years, many horses in Nova Scotia mines went underground and stayed there year in and year out. But that changed in the 1940s when miners started getting vacations and horses were brought up for their own vacation and turned out in a large field.

The impacts of coal dust on miners' health: A review
One of the important issue involved in coal mining is coal dust, which can lead to a series of health problems (Yao et al., 2020).Nearly the whole mining processes is accompanied by coal dust generation (Shahan and Reed, 2019).Fig. 2 depicts the processes of coal dust generation during mining, showing that dust is generated during …
Coal mining and chronic obstructive pulmonary disease: a
The potential of coal mine dust to cause disabling pneumoconiosis has long been recognised, but research now suggests that pneumoconiosis is not the only respiratory hazard of coal mining. Over the last 30 years evidence has accumulated that miners also experience an excess of chronic obstructive pulmonary disease (COPD), and this has …
