Abstract
Stratification of exhaust from a load haul dump was studied in an 80- foot-long dead end heading located in the White Pine Mine. The data substantiate the presence of strong buoyant forces of the hot exhaust gases that result in stratification in dead end headings. Results indicate that accurate field source quality control measurements can be obtained for CO2, CO, and NO but NO2 results were low for all engine conditions. Diesel pollutant concentration data from the Orchard Valley Mine were analyzed and compared with data collected earlier in the White Pine and Brushy Creek Mines. Lognormal frequency distributions and CO2-based concentration ratios and correlations were calculated. In the three mines compared, pollutant concentrations were distributed similarly, and concentrations appear to be controlled to present standards.
