Coal workers'' pneumoconiosis (CWP), also known as black lung disease or black lung, is caused by long-term exposure to coal dust is common in coal miners and others who work with coal. It is similar to both silicosis from inhaling silica dust and asbestosis from inhaling asbestos dust. Inhaled coal dust progressively builds up in the lungs and leads to inflammation, fibrosis, and in worse ...

 · Workers in China are also developing silicosis rapidly. 23 million workers are at risk of developing silicosis in China alone. Chinese health officials estimate 875,000 cases of silicosis nationwide, but workers believe there to be millions. Gold miners in South Africa have suffered from silicosis and tuberculosis for decades. Just last week, a ...

In particular, some of the most severe cases of silicosis have been observed in surface mine rock drillers [NIOSH 1992]. A voluntary surface coal miner lung screening study conducted in Pennsylvania in 1996 found that silicosis was directly related to age and years of drilling experience [CDC 2000].

 · The prevalence of silicosis in coal miners can be reliably determined only in autopsy studies. In the National Coal Workers'' Autopsy Study from 1972 to 1996, pathologic evaluations of 4115 autopsy cases found 23% of coal miners with pulmonary silicosis and 58% with lymph node silicosis.

Prior to 2014, they were not entitled to participate in the CWHSP. However, prior research had identified increased risk for silicosis in surface coal miners, particularly drillers. [40, 41] Using the CWHSP mobile unit, NIOSH conducted targeted outreach during 2010 and 2011, screening more than 2000 surface coal miners. Radiographic evidence of ...

The occurrence of pneumoconiosis in surface coal miners supports including them within a systematic respiratory health surveillance program. The current surveillance findings are consistent with past findings of pneumoconiosis, particularly silicosis, in surface mining occupations such as drilling a …

Of 1,623 coal miners seen by the Silicosis Medical Board for the three-year period I936-I938, only in 3.6 per cent of the cases was the sputum found positive. Keeping the two classes separate, the following are obtained among the different classes of workmen : COAL RISK + QUARRY RISK Pul. tub. Silico-tuberculosis Silicosis Rockmen 3 I o 15 ...

In 1983, a sentinel case of acute silicosis was reported in a surface coal mine driller. 28 The case report included reanalysis of surveillance conducted in US surface coal miners in the early 1970s showing that drill crew workers were at significantly increased risk for pneumoconiosis relative to other surface coal miners. Medical examinations ...

1.1 .I Miner or Coal Miner UMiner" or "coal miner" refers to any individual working in a surface or underground coal mine (including any worker employed by a contractor) who is (1) engaged in the extraction and production process, or (2) regularly exposed to mine hazards, or (3) employed as a construction, maintenance, or service worker.

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.

 · There are two basic types of coal mining operations, surface mining and underground mining, producing distinctively different exposure variables and disease entities. Underground coal miners are at greater risk of developing silicosis than strip or surface miners because of the higher dust levels in the underground environment.

 · INTRODUCTION. The recent reappearance of coal workers'' pneumoconiosis (CWP) 1, 2 and emergence of artificial stone (AS)-associated silicosis 3-5 has represented a failure of preventive systems to protect the respiratory health of workers in Australia. This resurgence of pneumoconiosis has occurred at a time when production has increased, mining techniques have been further mechanized …

What every physician needs to know: Coal workers'' pneumoconiosis (CWP) and silicosis are preventable occupational lung diseases that are typically associated with significant dust exposure. Although these diseases are two separate entities, they may occur concomitantly, especially in coal miners. Despite mandated dust controls, silicosis and coal workers'' pneumoconiosis remain …
