Achievements
Two million fatality free shifts
Murray & Roberts Cementation achieved a major milestone when the
company recorded two million fatality free shifts on August 12,
2006. This is the first instance where a mining contractor has
achieved a second consecutive million fatality free shifts in the
mining industry in South Africa.
The largest diameter shaft raisebored in the world
Murray & Roberts Cementation beat its own world record for the largest
shaft ever raisebored by a full metre when it completed the raiseboring
of three 7.1 metre diameter shafts at Sasol Mining’s Middelbult and
Bosjesspruit Mines in 2002.
The deepest single-drop shaft sink in the world
Murray & Roberts Cementation was responsible for sinking a 9 metre
diameter shaft to 2991 metres below collar at South Deep near Westonaria,
and equipping it with 7700 tons of steel. One of the design features of
this shaft is an internal suspended tower 385 meters long which isolates
the conveyance guides from future shaft movement in the vicinity of the
ore body.

toll mine the shallow platinum ore body at Kroondal in 1999. Production
