• Test Report on the Machine-Mounted Continuous Respirable Dust Monitor
  6/1/2001 - Conference papers
  The machine-mounted continuous respirable dust monitor (MMCRDM) is a fixed-location area sampling device developed for possible use at the working face of an underground coal mine. decades. Recently, an extensive series of laboratory and underground tes...
• Dust Underfoot: Enclosed Cab Floor Heaters Can Significantly Increase Operator's Respirable Dust Exposure
  4/1/2001 - Peer reviewed journal articles
  Many types of heavy equipment used in the mining and construction industries use enclosed cabs to protect equipment operators from dust and noise exposure. A cooperative research study with a mining company and a cab filtration company was conducted to...

• New Tools To Monitor Personal Exposure To Respirable Coal Mine Dust
  1/1/2001 - Conference papers
  The compliance sampling method for coal mine dust in the United States has not changed appreciably in the last 30 years. A call for more frequent sampling with immediately available results is leading to new instruments that may supplement or replace th...
• A Comparative Evaluation of the Differential-Pressure-Based Respirable Dust Dosimeter with the Personal Gravimetric Respirable Dust Sampler in Underground Coal Mines
  1/1/2001 - Conference papers
  This paper presents the results of a side-by-side comparison of the respirable dust dosimeter and gravimetric respirable dust sampler in a controlled experimental environent in the laboratory and in underground coal mines under normal operating conditions.
• Research by NIOSH for Controlling Respirable Dust and Methane Gas on Continuous Miner Faces
  1/1/2001 - Conference papers
  The importance of controlling respirable dust and methane gas levels in underground coal mining cannot be underestimated. While respirable dust can significantly affect the occupational health of underground coal miner, methane gas accumulations pose s...
• Reducing Worker Exposure To Dust Generated During Longwall Mining
  1/1/2001 - Conference papers
  Longwall mining equipment has improved dramatically over the last 15 years. Although significant gains in longwall dust control have been made, they have been challenged by significant increases in coal extraction rates resulting in more dust being gene...
