Final report July 1, 1994 to December 15, 1998, continuous dust monitor (CDM) for underground coal mines.
NIOSH 1998 Dec; :1-17
This is the nineteenth and last report of the contract launched July 1, 1994. In this report we describe the success of the coal dust monitor in providing both real-time and recorded dust concentration measurements. We also provide some suggestions for improving and enhancing the instrument. Under this contract R&P built and mine tested 1 "tethered" mass monitor (phase 1), built and mine tested 2 self-contained monitors (phase 2). We then constructed 10 monitors and provided several service calls (phase 4). The last R&P obligation under this contract is to conduct a training session scheduled for the week of January 4 to 8 at MSHA's Beckley Campus. Labor and travel charges for the training session will exhaust all remaining funds. A primary goal of this effort was to develop a machine -mounted coal dust monitor for underground mines which could provide accurate real-time information to the miners themselves for use in adjusting and maintaining their dust control equipment and strategies. Another primary goal was to provide recorded information which could be used by government and industry dust control engineers to study and improve work practices and equipment used for dust control. A secondary goal was to provide a tamper-resistant record of the coal dust concentration at the machine location, which when combined with correlation studies performed at a variety of sites, could be used to predict accurate dust exposures of the individual coal miners on a section or long wall crew.
