Description

The Jackpot is a hydraulic pre-stressing device for underground mine roof support. It was developed by New Concept Mining in the late 1990s and has established itself as the market leader in the field. The Jackpot pre-stresses timber mine props at the time of installation, and so provides an immediate, active support to the roof of the mine, providing underground workers with a much safer environment.
Jackpots are essentially hydraulic jacks which are placed on top of timber props and then inflated with high-pressure water through a non-return valve. Under pressures of 120 to 140 bar they expand axially and load the mine props to between 20 t and 50 t, locking the props into place and compressing the roof of the mine. This compression closes cracks in the roof and secures loose blocks of rock, in the process reducing groundfalls, the biggest killer in the mining industry.

The product has a number of innovative features. One of these is the patented "roll-over" inflation mechanism, which accommodates difficult installations and provides blast resistance to the support. It is widely used in gold and platinum mines, and its design has proved to be tolerant to varying conditions and installation workmanship.

Jackpots are exported worldwide, from Australia and Fiji to Germany and the Americas.
