Underground Mine Ventilation Case Study 1

A deep-level gold mine in the Witwatersrand Basin, South Africa, operating at depths exceeding 3,200 m below surface. The mine comprises 14 active levels, 85 km of development and production drifts, and produces ~250,000 tonnes of ore per month. Ventilation demand driven by heat load (geothermal gradient >28°C/km), diesel emissions, and dust control.

Challenge: Maintaining statutory airflow (≥2.5 m/s) and temperature (<29°C WBGT) at the dee...

Underground Mine Ventilation Case Study 2

A deep-level gold mine in the Witwatersrand Basin, South Africa, operating at depths exceeding 3,200 m below surface. The mine comprises 14 active levels across a 25 km² orebody, with 82 km of development and production drifts, servicing 42 working faces and supporting 1,200 underground personnel per shift.

Challenge: Maintaining statutory airflow (≥ 6 m³/s per worker) and temperature control (< 2...
