CDC Mining Topic Respiratory Diseases NIOSH

Oct 16, 2020· The two main types of pneumoconioses that affect miners are coal workers’ pneumoconiosis (CWP), commonly called black lung, and silicosis. CWP is associated with coal mining, but silicosis can affect workers in many types of mines and quarries, including coal mines. Medical treatment cannot cure these diseases, so preventing them through

China’s Deadly Mining Industry Pulitzer Center

About 6 million people in China have pneumoconiosis, according to a local NGO. Once they are ill, these men find it very difficult to get help, both legal and medical. Often, they are simply sitting in their village homes, tucked away in the mountains, helpless. This is a portrait of former gold miners

In the recent Chinese documentary Miners, Grooms, and Pneumoconiosis (2019), the former miner Zhao Pinfeng contracts pneumoconiosis, a deadly occupational lung disease caused by inhaling mineral dust created by mining operations. After spending most of his meagre savings on medical expenses, Zhao eventually passes away, leaving his wife and two

Industrial Dust Diseases. About Industrial Dust Diseases

Oct 20, 2014· The term 'pneumoconiosis' refers to a group of lung diseases caused by the inhalation and retention of dust in the lung. This causes a range of granulomatous and fibrotic changes. In modern times, the most commonly occurring variant, apart from asbestosis, is coal worker's pneumoconiosis (CWP), arising from the inhalation of coal dust.

Comparison of lung function in miners and other occupations. A series of early studies by the MRC Pneumoconiosis Research Unit in South Wales found significantly lower mean levels of indirect maximum breathing capacity (IMBC) in miners and ex-miners than in non-miners of the same age.2 However, there was no clear relation between IMBC and duration of underground or face work.

Pathology of Pneumoconiosis Dr Sampurna Roy MD

Pneumoconiosis may be classified as either fibrotic or nonfibrotic, according to the presence or absence of fibrosis. Silicosis, coal worker pneumoconiosis, asbestosis, berylliosis, and talcosis are examples of fibrotic pneumoconiosis. It is not unusual for a gold miner, for example, to become a coal miner. In addition, mining of a
