Coal mine dust causes a range of lung diseases, collectively called coal mine dust lung diseases. ... 2017 revealed that the percentage of silica-containing respirable dust was significantly higher in Central Appalachian underground mines compared with those in the rest of the U.S. suggesting the greatest potential for …
Within the coal mine subsample, the probability of a mine reporting a lung disease was found to be greater for underground as opposed to surface types (by 2.73 to 3.40 times) and in the Appalachian region as opposed to the remaining regions of the United States (8.00 to 9.78 times).
and disease could be improved by identifying why and under what specific conditions illnesses occur (i.e., what are the primary causes of illness or disease in the mining industry?). The frequency of disease or illness from 1983-2001 (figure 5) shows a roller-coaster effect for illness and disease rates in the mining industry.

In 2010, people everywhere were riveted to the story of the 33 miners in Chile trapped 2,300 feet (700 meters) beneath the Earth's surface in a copper …
Although the mining of these minerals generates wealth for the country, it also causes diseases in the mine workers who are exposed to harmful dust. Pulmonary silicosis, the disease most commonly caused by exposure to crystalline silica dust, was described in South African gold miners in the early 1900s – not many years after gold …
Underground mining is one of the most rigorously regulated sectors in Canada, and rightfully so. Even though the number of work-related accidents and fatalities has decreased over the years, serious injuries continue to be reported each year. An even stronger emphasis on appropriate safety training for all miners is therefore necessary.

Underground mining has historically occurred in surface and near-surface (shallow) mineral deposits. While no universal definition of deep underground mining exists, humanity's need for non-renewable natural resources has inevitably pushed the boundaries of possibility in terms of environmental and technological constraints.
Coal mine dust causes a range of lung diseases, collectively called coal mine dust lung diseases. Examples include coal workers' pneumoconiosis (CWP), a dust …

Mining activities, both surface and underground, come along with numerous health externalities and exposure to dust and chemicals from mining causes acute and chronic respiratory diseases. It is hypothesized that this could even be more in limited resource settings, where mining regulations are less enforced and the safety of …
Of approximately 261,784 total mining company employees in 2012, approximately 66,044 (25.2%), 92,472 (35.3%), and 103,268 (39.4%) were employed in the MNM, coal, and stone, sand, and gravel mining industry sectors, respectively, not including an additional 126,094 contractors. 2 Similar to the coal sector, MNM mining comprises …
Second, age and mining tenure were self-reported, which could affect comparisons of tenure-adjusted disease prevalence. Finally, estimates of the prevalence of CWP and PMF included assessment of miners with underground mining experience, 155 (6.9%) of whom had ≥25% of their total mining tenure in underground mines.
Underground coal mining is far more dangerous than surface mining, including the loathsome removal of whole mountaintops to access coal seams. One …
While younger cohorts had higher odds of death compared to older cohorts, all mining cohorts had consistently and significantly elevated odds of death from chronic lower respiratory diseases, the …
INTRODUCTION. Cardiovascular disease is the leading cause of death in both men and women in the United States (U.S.), amounting to 610,000 deaths in 2015 (1, 2).It is the leading cause of death among blacks, Hispanics, and non-Hispanic whites, but is second to cancer among American Indians or Alaska natives as well as Asians or Pacific …

Occupational diseases reported to the DMRE. Reports from all mines showed a decrease of 4.2% in the total number of occupational diseases reported by mines, from 2,013 cases in 2020 to 1,924 cases in 2021. TB and silicosis declined by 6.6% and 11.4% respectively while noise induced hearing loss (NIHL) increased by 5.1%.

For decades, miners have called for limits on highly toxic silica dust, which they're exposed to while mining. An investigation shows its impact and the weakness of proposed rules to protect them.
Background: Exposure to respirable coal mine dust can cause pneumoconiosis, an irreversible lung disease that can be debilitating. The mass concentration and quartz mass percent of respirable coal mine dust samples (annually, by occupation, by geographic region) from surface coal mines and surface facilities at U.S. underground mines during …

What does an underground (hard rock) miner do? Back to top. Anyone working underground to mine hard minerals such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead may be exposed to many hazards. The same processes are used for mining hard gems like diamonds. Soft rock miners excavate softer minerals …
Mining, however, can lead to an increased risk of contracting other diseases: increased pulmonary tuberculosis has been recorded in underground Cu miners in Zambia . A high prevalence of wheeze (a symptom of asthma) and rhino-conjunctivitis has been noted among the elderly in communities located near mine dumps [ 78 •].
Underground Mining. It is one of humanity's oldest and most impressive engineering activities, extracting an ore or mineral from many hundreds of feet deep. ... pneumococcal disease and the dreaded 'black lung' often associated with coal mining. Fumes from welding equipment, heavy machinery, and often the mined materials themselves can be ...
The demand for minerals is increasing unceasingly throughout the world. In order to meet the demand, underground mines are operated at greater depths using high capacity machinery [1, 2].Increasing mining depth and upgrading of mine mechanization are the prime causes of heat hazard, which is a major concern in deep underground …
