A household name for shaft sinking in Africa’s mining sector, Murray & Roberts Cementation has over the decades developed a wide portfolio of mining services – some better known than others.
“Through our constant innovation across a range of fields, built on the expertise of our highly experienced staff, we keep developing very interesting responses to customer’s challenges,” says Pieter Oosthuysen, Senior Project Manager at Murray & Roberts Cementation.
Among the sector’s growing challenges has been the criminality associated with illegal mining activities. The company has developed solutions to prevent cable theft – including the encasing of cables in grout-filled pipes – and to seal off old areas using grout packs that create permanent barriers.
“Water management has also become a key issue for mines, especially in the mature deep-level gold mining sector,” says Oosthuysen. “Here, their issues are about ensuring responsible water management as well as reducing pumping costs from dormant or mined-out mining areas. This often requires that old underground areas be sealed off to contain the massive water pressures at depth.”
