In general, for platinum mines, underground air cooler systems (and service water systems) will be served with chilled water from surface-located refrigeration machinery. This is different from the 'generic' gold mine practice in terms of the hierarchy-with-depth framework. In general, by the time significant underground air cooling systems are
For mining jurisdictions, requiring a DEE dilution airflow of 0.05 m³/s/kW, the maximum distance that can be ventilated using parallel systems each consisting of a 2 x 110 kW, 1,400 mm diameter fan combined with 1.4 m diameter duct is 1,500 m (23 m³/s per duct, delivered to the face), based on the prescribed haulage fleet.

The Handbook has its origins in a Chamber 1947 publication on the "Quality of Mine Air: Dust Content and Cooling Power" which contained recommendations for standard practice on gold mines with regard to thermal precipitator and konimeter practice, a deep-cell method of counting particles in mine water and kata thermometer practice.
Mining provides the mineral resources and metals needed by sectors such as construction and technology. Assess the environmental impact of your mining operations in real-time and start protecting your environment and people's health. It is up to you to ensure that this is done while guaranteeing optimal air quality.
