### sec.362 Air distribution The ventilation officer for an underground mine must ensure the mine’s air quality and flow rate is measured and recorded under this section as often as is necessary, having regard to the circumstances at the mine, but at least once each month. The air quality and flow rate must be measured at the following places— each main intake airway at a point as near as practicable to the surface; each intake airway on the return side of the seals over which the intake air passes; each main return airway at a point as near as practicable to the surface; each return airway of each ventilation split at a point as near as practicable to the surface; the return airway from each goaf area and each set of workings; each return airway at a main upcast fan; any other place the ventilation officer considers necessary; any other place required by an inspector. The air flow rate must be calculated and recorded for each of the following— the combined intake airways; the combined return airways; each ventilation split. Also, at least once in each working shift at the mine, the air flow rate must be measured and recorded for each of the mine’s working faces. The ventilation officer must also ensure the mine’s atmosphere is monitored for internal combustion engine pollutants as required under the mine’s safety and health management system. s 362 amd 2020 SL No. 118 s 20 (sec.362-ssec.1) The ventilation officer for an underground mine must ensure the mine’s air quality and flow rate is measured and recorded under this section as often as is necessary, having regard to the circumstances at the mine, but at least once each month. (sec.362-ssec.2) The air quality and flow rate must be measured at the following places— each main intake airway at a point as near as practicable to the surface; each intake airway on the return side of the seals over which the intake air passes; each main return airway at a point as near as practicable to the surface; each return airway of each ventilation split at a point as near as practicable to the surface; the return airway from each goaf area and each set of workings; each return airway at a main upcast fan; any other place the ventilation officer considers necessary; any other place required by an inspector. (sec.362-ssec.3) The air flow rate must be calculated and recorded for each of the following— the combined intake airways; the combined return airways; each ventilation split. (sec.362-ssec.4) Also, at least once in each working shift at the mine, the air flow rate must be measured and recorded for each of the mine’s working faces. (sec.362-ssec.5) The ventilation officer must also ensure the mine’s atmosphere is monitored for internal combustion engine pollutants as required under the mine’s safety and health management system. - (a) each main intake airway at a point as near as practicable to the surface; - (b) each intake airway on the return side of the seals over which the intake air passes; - (c) each main return airway at a point as near as practicable to the surface; - (d) each return airway of each ventilation split at a point as near as practicable to the surface; - (e) the return airway from each goaf area and each set of workings; - (f) each return airway at a main upcast fan; - (g) any other place the ventilation officer considers necessary; - (h) any other place required by an inspector. - (a) the combined intake airways; - (b) the combined return airways; - (c) each ventilation split.
