Abstract
The Bureau of Mines, U.S. Department of the Interior, conducts research to improve instruments and methods for measuring respirable dust levels in mines. This presentation includes new information on the performance of the coal mine dust personal sampling unit (CMDPSU), a brief description of some recently developed dust monitors, a summary of the most recent test results, and suggestions on how to best use respirable dust monitors, both new and old,in the mining environment. Recently developed monitors include the real-time aerosol monitor (RAM-I), the MINIRAM, the continuous respirable dust monitoring system (CRDMS) , and the. tapered-element oscillating microbalance (TEOM). The RAM-I, a commercially available nephelometer, has been extensively tested and widely used by Bureau of Mines research personnel. The MINIRAM, also a commercially available nephelometer, is currently being field evaluated by the National Institute for Occupational Safety and Health (NIOSH) , U. S. Department of Health and Human Services, and the Bureau of Mines. The CRDMS, a prototype nephelometer, is not commercially available and is being tested in the laboratory. The TEOM is an experimental prototype. It relates the frequency of oscillation of a special tapered element-filter combination to the mass of dust collected on the filter.
