چکیده

In 1991 the Mine Safety and Health Administration conducted a special program to assess occupational exposures to respirable coal mine dust in underground coal mines. Priority was given to longwall mining operations, mines with a history ofhaving a problem controlling dust to the applicable standard, and a representative number of all other mines. Measurements were obtained on approximately 720 mechanized mining units (MMUs) representing 615 mines. Respirable dust measurements were obtained on at least five occupations on each MMU. Extensive data were also gathered at the time measurements were obtained on the amount of material extracted and procedures in place to control dust. Tills article presents the results of occupational exposure measurements and discusses the influence of production and methods used to control dust on occupational exposures.

Evaluation of occupational exposures to respirable dust in underground coal mines.

Dust can be produced by almost all mining operations in underground coal mines and seen all around the mine. Different occupational groups get exposed to different dust levels and in order to minimize the probability of developing coal workers' pneumoconiosis (CWP), it is necessary to investigate the workers exposed to dust. This study aimed to evaluate the dust concentration conditions in unde...

A Comparative Evaluation of the Differential-pressure-based Respirable Dust Dosimeter with the Personal Gravimetric Respirable Dust Sampler in Underground Coal Mines

The development of a sampling instrument for the assessment of an underground coal miner’s exposure to airborne respirable coal mine dust on a continuous and real-time basis has been long identified as essential for timely initiation of control actions. A respirable dust dosimeter (RDD) which operates on the principle of increasing pressure across a filter media with increasing dust mass on the...

Controlling respirable dust in underground coal mines in the United States

As mining operations in the United States (US) have become more productive, con­ trolling the dust exposure of mine workers has become more challenging. In response, US mining operations are applying basic controls at elevated levels and are looking to emerging control tech­ nologies in an effort to better control airborne respirable dust levels. The Pittsburgh Research Laboratory (PRL) of the ...

Exposure-response relationships for coal mine dust and obstructive lung disease following enactment of the Federal Coal Mine Health and Safety Act of 1969.

Underground U.S. coal miners were studied cross-sectionally for the association of respirable coal mine dust exposure with pulmonary function and symptoms of airways obstruction. The study group included 1,185 miners participating in Round 4 of the National Study of Coal Workers' Pneumoconiosis who had started mining in or after 1970 when comprehensive exposure regulations first came into effec...

Investigation into Dust Exposures and Mining Practices in Mines in the Southern Appalachian Region

Recent NIOSH published information has shown an increase of rapidly progressive coal workers’ pneumoconiosis (CWP) in the southern Appalachian coal region (SAR) of the U.S., despite the fact that compliance data indicates that most coal miners have been exposed to coal mine dust concentrations below the statutory limit of 2.0 mg/m3. While the exact cause of these elevated CWP levels in the SAR ...
