The objective of this work was to develop and test engineering approaches to the control of air quality for the protection of miners health in dieselized underground mines. A general experimental approach was developed by which instruments could be compared for the measurement of diesel exhaust pollutant concentrations in the 0.5 to 5 threshold limit value (tlv) range. Drager detector tube diluted exhaust CO, co2, no, and NO2 measurements were compared with simultaneously taken portable instrument measurements. The effects of two exhaust system configurations on the pollutant concentrations in a deadend heading were studied. Both directed gases toward the crosscut and improved the stratification of the air in the heading.
