Descender – Ore Pass

CIS Descender - Ore Pass Modular Raise Lining Solution

A Modular Solution to Ore Pass Failure

Descender is a permanent ore pass solution that provides wear resistant, structural reinforcement installed from the top to bottom of an ore pass. In the event of an ore pass failure, our modular lining system can have you back in full production, quickly, efficiently, and permanently.

  • Safe installation
  • Small work area footprint
  • Easy to mobilize and set-up
  • Installed in days or weeks (rather than months or years)
  • Fully customizable to meet your requirements

 

Protect and Preserve

MOVE ORE EFFICIENTLY

The movement of ore is critical to an underground mining operation. Millions of dollars are spent developing and constructing muck circuits, which are integral to mine output. Descender Ore Pass is a cost-effective solution for protecting and preserving these passes from deterioration through the use of a customizable lining system. Quickly mobilized and installed, Descender is also ideal for rehabilitation of existing Ore Passes getting you back to optimal production as soon as possible.

Increased Uptime

ENSURING LOWER COSTS

Relative to overall mine infrastructure costs, ore pass development is relatively cheap. Comparatively, losses in the event of failure can be excessive, compacted by the fact that once degradation of the wall structure has begun, conventional methods of rehabilitation have had insufficient results. Unless the pass is abandoned altogether due to feasibility issues, mandatory recovery methods are employed. However, they are ineffective, dangerous, costly, and can continue for months, sometimes years, without any guarantees of renewed production. In the event of an ore pass failure, CIS Descender can have you back at full production within weeks.

Reliable Flow-Through

DELIVERED FAST

Ore pass design has always involved some compromise between cost, production reliability, efficiencies, and contingency planning. More efficient flow-through designs come with added expense due to necessary (and costly) contingency measures. Muck moves more freely with this scheme. However, it degrades the ore pass at a faster rate resulting in early failure. Any of the following can contribute to ore pass loss: structural breakdown, scaling of walls, impact, abrasion and blast damage. Descender virtually eliminates these factors by installing a solid, wear resistant structure from top to bottom.
