Diamond Mine Safety

Petra Diamond’s Finsch Diamond Mine in the Northern Cape has purchased a fleet of Sandvik dry drilling bolters to support mining operations at the new Block 5 sub-level cave development.

The machines promote additional safety in the kimberlitic ground of the diamond mine which necessitates dry drilling in favour of the usual wateraided equipment. Water is known to lead to the rapid decomposition of certain kimberlite types, which in turn could lead to larger support holes

than originally designed, compromised ground support elements and eventually support failure, leading to the tunnel’s instability.

As an additional measure the new rock bolters are completely mechanised and controlled by a single operator from under a FOPS safety canopy. The new section also requires high production outputs and the bolters are capable of installing between seven to eight rock bolts per hour, including welded mesh sheets.

A joint solution between Sandvik and dust suppression experts, Ilmeg, has enabled the usually ‘dusty’ dry drilling of the rock to be conducted under nearly dust-free conditions which not only contributes to better visibility and respiratory safety, but also creates a cleaner and more sanitised environment for miners to operate in.
