(ss. 100.1 and 102)
MINIMUM VENTILATION RATE ( CANMET CERTIFICATION
The minimum ventilation rate of a diesel engine used in an underground mine shall be the higher of the values calculated in accordance with the following methods:
(a) the rate required to dilute contaminants in the exhaust gases in accordance with CAN/CSA Standard M424.2M90, Non-Rail-Bound Diesel-Powered Machines for Use in Non-Gassy Underground Mines or CAN/CSA Standard M424.1-88, Flameproof Non-Rail-Bound Diesel-Powered Machines for Use in Gassy Underground Coal Mines, as the case may be;
(b) the rate required to dilute the predominant contaminant to a concentration equal to the value of the denominator, which represents the contaminant, where the value calculated in accordance with paragraph a is insufficient to dilute the combustion emissions indicated in the equation below to concentrations lower than the respective individual value of the denominator in that equation for each of the contaminants.
Equation:
EQI= CO + NO + RCD + 1.5 [SO2 + RCD] + 1.2 [ NO2 + RCD]
