Scope:

The shotcrete specification for the NPM Lift 2 expansion project called for "synthetic fibre only" due to ongoing electrical short circuit damage to mining equipment caused by previously used steel fibre.
Rock burst conditions dictated a Toughness requirement of 380 Joules energy absorption on the Round Determinate Panel (RDP) test method.

Solution:

Barchip fibre reinforced shotcrete application to all underground excavation, including access declines, crusher station and draw points.
