Pathological study of the prevalence of silicosis among

There are two basic types of coal mining operations, surface mining and underground mining, producing distinctively different exposure variables and disease entiti 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.

Work-Related Lung Disease (WoRLD) Surveillance Report

Coal Workers’ X-ray Surveillance Program, NIOSH The Coal Workers' X-ray Surveillance Program (CWXSP) is a NIOSH-administered occupational health program initially mandated by the Coal Mine Health and Safety Act of 1969 The primary objective of the CWXSP is to screen miners for coal workers' pneumoconiosis (CWP).

Silicosis and Coal Workers’ Pneumoconiosis

Etiology Silicosis and coal workers' pneumoconiosis (CWP) are occupational lung diseases; silicosis is caused by continued exposure to excessive amounts of respirable silica, and CWP is caused by exposure to carbonaceous material (anthracosis) Respirable crystalline silicate and coal dust embed in the lungs, causing granulomatous and fibrotic changes that lead to radiographic and pathologic.

Coalworker's pneumoconiosis

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

Silicosis

Case Discussion Pneumoconiosis is lung disease secondarily to the exposure to inorganic dusts, in many developed countries related to now decaying industries such as coal mining The prolonged expsoure to these dusts can give rise to lung fibrosis, which on occasion may progress to a conglomerate form mimicking masses in the lungs (PMF).

US Miners Demand Better Protection From Silica

For coal dust, the current Coal Mine Dust Rule measures all respirable coal dust in a coal mine, lumping coal dust with silica However judging by their respective permissible exposure limits, silica is fifteen to thirty times more fibrogenic than coal dust, making it many times more dangerous to miners’ lungs What are black lung and silicosis?.
