In the work described in this Bureau of Mines paper, a simulated diesel mucking operation was carried out in the exxon colony pilot mine in Colorado to establish expected levels of diesel pollutants in dead-ended working headings. This heading was nominally 15.3M (50 ft) wide by 9.2M (30 ft) high. Two face ventilation systems were tested using sulfur hexafluoride tracer gas to represent the diesel pollutants. The results of these tests showed that conventional face ventilation systems operating at high flow rates could adequately ventilate diesel equipment in the 447-to-522-kw (600- to 700-hp) range, even in a dead heading 91.4M (300 ft) long.
