Abstract [en]

Ventilation is the primary means of diluting atmospheric contaminants in underground mines. The majority of equipment in underground hard rock mines are diesel powered vehicles, which produce toxic gases such as Carbon Monoxide (CO) and Oxides of Nitrogen (NOx), as well as carcinogenic Diesel Particulate Matter (DPM). The airflow quantity for an underground mine is usually based on the engine power of diesel vehicles used in the mine, multiplied by unit airflow requirement, such as 0.05 to 0.06 cubic metre per second per kilowatt engine power (m3/s per kW) used in Australia or 0.047 to 0.092 m3/s per kW used in Canada. These unit airflow requirements are stated in local mining Occupational Health & Safety (OH&S) regulations.

However, the origin of these unit requirements is not clear, i.e. whether they are derived from scientific studies or are empirically based. Due to this, it is impossible to ensure that the values stated in the regulations are sufficient to dilute contaminants emitted by diesel equipment. This paper traces the history of these requirements based on literature review and online interviews with fellow underground ventilation practitioners and academics to find the origin of these requirements. A review of the relevance of these requirements in today’s situation is also outlined in this paper.
