Rocprop

The Rocprop is an steel elongate roof support, that was originally designed for deep level gold mines for use in tubular ore bodies with mining widths of up to 6m. Available in 20 and 40 ton variants it is an all-steel elongated support system with predictable and repeated performance thereby catering for static and dynamic load conditions and ensuring availability of the excavation for its life span.

Under static load conditions it sustains constant load-bearing characteristics during blasting and maintains the integrity of the hanging roof during closure. In both static conditions and in seismically active mines it provides a constant resistance to prevent fall of ground.

The Rocprop is available in three different diameters with lengths from 1m - 6m in 20ton and 1m-3.5m in 40ton load capacity. (See size chart)

The graph depicts the typical load deformation performance of the Rocprop.

Rocprop Load Deformation

  • Lightweight
  • Easy to install
  • Colour coded to identify ranges
  • Dynamic yielding capability
  • No creep under static conditions
  • Consistent loading therefore no uneven loading on hanging wall
