BBE’s expertise in ventilation, cooling, energy control, pollutant control, water quality/treatment and fire engineering in underground mines has contributed to many applied research programmes in the mining industry (e.g. SIMRAC, MHSC, DeepMine, FutureMine, ESKOM DSM). BBE engineers have also contributed significantly to the state-of-the-art of mine ventilation and cooling technology, including the evaluation of novel cooling systems (e.g. recirculation, ice and hydropower), analysing the effects of numerous novel mining methods and developing South Africa’s first CSP system. BBE holds a number of patents related to novel cooling systems and has an ongoing development programme for reducing cooling costs and minimising energy consumption. Indeed, against most other trends, BBE clients have been enjoying a reduction in the costs of cooling and ventilation.
