High Volume Grouts

COMPREHENSIVE RANGE. HIGH VOLUME OUTPUT.

Our high volume output grouts produce significantly larger outputs than traditional cement grouts. This is beneficial as significantly less amounts of physical materials are required to be transported. Product range includes numerous foaming and non-foaming grouts.

Applications include:

  • Explosion resistant ventilation seals
  • Underground cavity filling
  • Collapsed roadway recovery
  • Backfilling behind steel sets and sidewall stabilisation
  • Rockfill consolidation and pillar support

Advantages
  • RAPID STRENGTH GAIN
  • REMOTE PUMPING
  • DURABLE & RELIABLE
All products are supplied pre-blended and pre-packaged requiring only the addition of set amounts of water to produce consistent quality grouts. Purpose designed placer pump units are used to continuously place the range.

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.

Tekpak® P System

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
