Pulmonary tuberculosis (PTB) among underground miners exposed to silica remains a global problem. Although well described in gold and coal mining, risk in other mining entities are not as well documented. This study aims to determine dustrelated dose response risk for PTB among underground miners exposed to silica dust in Zambia's copper mines.

After passage of the Federal Coal Mine Health and Safety Act of 1969 (), measures were adopted to limit exposure to respirable dust in coal mines, along with active surveillance of miners' lung health based on work history, chest radiographs, and activities were temporally associated with a steady decline, from 1970 until about 2000, in the prevalence of coal workers ...
The Mine Safety and Health Administration (MSHA) is requesting comments on the proposed rule published in the Federal Register on October 19, 2010, addressing Lowering Miners' Exposure to Respirable Coal Mine Dust, Including Continuous Personal Dust .
1 天前· The miners were asked about their work histories, their exposure to coal and toxic silica dust, safety practices at work, pressure to cut corners on dust controls, federal mine inspectors, the ...
Inhalation of coal mine dust causes coal workers' pneumoconiosis (CWP) and other diseases affecting lung function. The prevalence of CWP among US coal miners has doubled since the late 1990s. Previously, small mine size (≤50 employees) was associated with increased risk of CWP, but it is unclear whether mine size is associated with risk of abnormal
Coal mining remains a sizable industry, with millions of working and retired coal miners worldwide. This article provides an update on recent advances in the understanding of respiratory health issues in coal miners and focuses on the spectrum of disease caused by inhalation of coal mine dust, termed coal mine dust lung disease.
7 天前· 'Mine 9' opens Friday, July 19, at The Flicks. Mine 9, a lowbudget but highoctane film, does not advocate for or against America's controversial legacy of coal, it lionizes the ...
Mine Dust and Pulmonary Health Tripathy DP* Department of Mining Engineering, India ... recommending a reduction in the exposure limit for coal mine dust, NIOSH also recommended a change in the ... Respiratory Morbidity of Former and Current US Coal Miners. American Journal of Public Health 105(12):
Coal workers' pneumoconiosis (CWP) is a chronic and irreversible occupational lung disease caused by inhaling coal dust or silicon dust in production environment among coal miners. At present, the prevalence of CWP is high in China and the incidence of CWP .
Jul 15, 2016· Recent cases of black lung in Queensland coal miners after many years of no known cases have raised important questions about control of dust exposure in coal mines. Why the health scheme for coal ...
23rd May 2019. The NSW Resources Regulator is urging current and former coal mine workers to maintain regular health screening after releasing the findings of its investigation into a former coal mine worker diagnosed with a mixed dust disease in 2017.
Jun 29, 2018· A new report from the National Academy of Sciences says the coal mining industry needs a "fundamental shift" in the way it controls exposure to coal and rock dust .
The Bureau of Mines handbook presents guidelines for controlling dust in underground roomandpillar coal mines. The dustcontrol techniques presented are primarily directed toward costeffectiveness for the operators of small mines facing tightened Federal regulations due to .
Abstract Exposure of miners to respirable coal mine dust and to respirable quartz silica at surface coal mines in the United States during 1982–1986 were evaluated by job category using data collected by coal mine operators and Mine Safety and Health Administration (MSHA) inspectors. Average coal mine dust concentrations were usually well below the MSHA Permissible Exposure Limit (PEL) for ...
Respirable Coal Mine Dusts In May 2014, the Mine Safety and Health Administration (MSHA) released a new rule regarding respirable coal mine dust exposures [10]. By August 2016, the permissible exposure limit (PEL) will be reduced from to mg/m3 in production areas of mines; and from
The burning of coal, oil and wood as fuel can cause mercury to become airborne, as can burning wastes that contain mercury. This airborne mercury can fall to the ground in raindrops, in dust, or simply due to gravity (known as "air deposition").
5 天前· The above example highlights the need for continuous development of electron microscopy methods to ensure more precision when characterizing mine dust. Similar situations apply to mine dust in the US, where regulations introduced in 2010 change sampling rules and reduce the allowed dust concentration.
MSHA's final rule to lower miners' exposure to respirable coal mine dust is a historic step forward in the effort to end black lung disease. The rule reduces overall dust standards in coal mines, improves the dust sampling technology and methodology, and expands the medical surveillance program to improve early detection of the disease.
