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

Pumpable Cribs

Minova's Pumpable Crib system has been developed to provide enhanced standing and roof support in underground coal mining. Typically installed for gateroad secondary support, Pumpable Cribs are a cost effective alternative to tin cans or timber cribs. Our system provides a more productive means to install standing support in longwall mining operations, reducing exposure for operational personnel and more cost effective mine production. 

Using our patented Tekpak® P technology, we allow you the flexibility to install Pumpable Cribs from the one surface location. A surface to seam operation allows mines to reduce equipment and material movements underground along with reduced operators underground.

We have invested in full scale testing of our Pumpable Crib's at an Australian NATA accredited facility, giving our customers confidence that our Pumpable Crib technology will perform to Australian conditions.

FB200

Our FB200 low viscosity, high yield grout is used for many applications within underground mines. We have 20 years experience in using FB200 for stabilising rockfill to enhance stope extraction, constructing explosion rated ventilation seals, filling of large voids and constructing false pillars for pre-driven recovery roads.

We have developed variants for hostile conditions such as saline water, hot water and long distance pumping.

Typically pumped at a 2:1 water:powder ratio, FB200 can be used between 1:1 and 3:1 ratios depending on individual project requirements.

FB200 is supplied as a ready to use free flowing blended cementitious powder that only requires the addition of water in a suitable placing machine.
