Abstract
The United States experience with using diesel equipment in underground mines was discussed. Research done by Michigan Technological University to apply and develop instrumentation for characterizing mine air was summarized. The work which was performed under contract to the Mining Enforcement and Safety Administration (MESA) consisted of two phases: applying the latest available portable instruments to monitoring diesel exhaust emissions in mine air, and designing a portable instrument package for use in underground mines. Portable instruments for monitoring carbon- monoxide (630080), nitric-oxide (10102439), nitrogen-dioxide (10102440), or carbon-dioxide (124389) emissions from diesel engines, a nitrogen-dioxide dosimeter, and a machine mounted carbon- dioxide detector were evaluated during the first phase of the project. Field tests showed that carbon-dioxide concentrations were well correlated with the concentrations of carbon-monoxide, nitric- oxide, and nitrogen-dioxide when a diesel engine was operating in a confined space and rebreathing its own exhaust. The portable underground monitoring laboratory developed in phase 2 could monitor up to four preselected sampling sites. It could monitor carbon- monoxide in four concentration ranges at concentrations up to 2500 parts per million (ppm), carbon-dioxide in three ranges at concentrations of 0 to 5 percent, nitric-oxide and nitrogen-dioxide in four ranges including concentrations of 0 to 500ppm, and dust in ten geometric size increments ranging from 0.0032 to 1 micron and concentrations up to 1 milligram per cubic meter. The portable instrument package was used in an epidemiological study conducted by MESA of the incidence of respiratory disease in miners exposed to silica and diesel exhausts. Monitoring data obtained in 22 mines indicated that exposures were generally below the current standards.
