Tekpak® P System

TWO PART SYSTEM. PUMPABLE CRIBS.

Minova's Tekpak® P Pumpable Crib System has been specifically developed to provide enhanced standing and roof support in underground coal mining and offers substantial benefits in terms of roof control, speed and ease of installation.

Tekpak® P is a two part chemical system consisting of Tekcem® P and Tekbent® which when mixed together rapidly reacts to produce a load bearing crib. Tekcem® P is a blended cementitous powder which forms an easy to pump slurry when mixed with water, remaining pumpable for 24 hours. Tekbent® is a low viscosity non setting liquid with an indefinite pumping life.

The system provides a more productive means to install roof support in longwall mining operations, providing increased safety for operational personnel and more cost effective mine production.

• High early strength allows pumpable cribs to begin taking loads quickly, with 50% of the final 28 day strength achieved within 3 hours

• A rapid gel time of 20 seconds allows each pumpable crib to be filled within one lift and to completely pressurise the crib to the roof

• Suitable for use with surface to seam applications
