Stabilisation for Portals

RIX offers quality mine stabilisation solutions delivered by positive, safety-conscious, multi-skilled teams, led by our highly-experienced management, who are experts in all aspects of:

  • Shotcreting
  • Slope, embankment, high wall, portal and underground stabilisation
  • Rope access
  • Tele-remote shotcrete shaft lining

Pictured above, our specialised Drilling & Rock Bolting Teams were on site for eight months, where our scope included:

  • Working with our client to assist with design, project set-up and programing
  • Providing detailed excavating
  • Drilling and installing 4,000 passive bolts
  • Placing 2km of strip drains
  • Stabilising the entrance to the drift portals with shotcrete and rock bolts
  • Applying 18,000m² of bar chip structural synthetic fibre-reinforced shotcrete
  • Ensuring the uninterrupted progress of the drift construction

Left: A new coal mine project consisted of a 250m by 300m wide, 35-40m deep box and three drift tunnels down to the longwall unit at the coal deposit. A total of three drift portals were constructed –  one for ventilation, another for transport and a final one for the conveyor to remove the mined coal.

Right: The risk of rockfall was mitigated with rockfall netting at this rail tunnel portal in Southern NSW. Our specialist Rope Access Teams were able to drill and install rockbolts and rock fall protection to both faces at great height, which was difficult to achieve with cranes or EWPs due to limited access above and to the portal areas.
