Longwall Respirable Dust Simulator
ROBERT A. HANEY Mine Safety and Health Administration, Pittsburgh Health Technology Center The effectiveness of these dust control techniques has been evaluated primarily through the use of instantaneous dust measurements. These instantaneous dust measurements give a relative indication of whether dust control and -------------------~ employee exposure improve or deteriorate. Because the instan...
متن کاملEvaluation 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...
متن کاملStudy to Assess Respirable Dust Exposures in Underground U.S. Coal Mines
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...
متن کاملA 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...
متن کاملControlling 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 ...
