Murray & Roberts Cementation has taken an innovative approach to a project that will see the establishment of two ventilation shafts — one upcast and one downcast —at Bokoni platinum mine on the northeast Limb of the Bushveld Complex in Limpopo, South Africa. For this project, the mining infrastructure, construction and services company has departed from the conventional blind sinking option in favour of bulk earthmoving and excavation methods. Project Manager Dirk Visser explains that Murray & Roberts Cementation conducted a trade-off study during the tender phase which revealed that taking a bulk earthmoving and excavation route would be more cost effective.
