MINING CONTRACTORS AND ENGINEERS
and safely, given the many competing demands for use of the mine’s shaft con- veyance. This challenge was overcome by establishing clear lines of communica- tion among all project stakeholders and proper planning as well as regular project meetings with the mine to discuss prog- ress, challenges, and solutions. With this constraint in mind, BBE aimed to design components required to construct the BAC, as much as possible, in sections that could fit into a cage rather than being slung beneath it, which is far more time consuming. BBE Projects has been assisting Harmony with ventilation and refrigera- tion upgrades at Tshepong North and South operations for the past few years with a major improvement in underground environmental conditions. The first proj- ect was a booster fan station on 66 level
at Tshepong South Operations (formerly known as Phakisa) in 2019. Since then, BBE has successfully commissioned an underground condenser fan sta- tion on 55 level at Tshepong South and two more booster fan stations at Tshepong North Operations on 66 level.
