Underground Roof Supports

Mine Arch 1

As underground mines get ever deeper in search of supplementary orebodies, bearing forces become a significant issue in tunnel stabilization. Existing tunnel support methods become less effective at greater depth, and the need for additional reinforcement increases.

With some of the deepest mines reaching four kilometres underground, global trends suggest.

 Incidents of rock bursts and tunnel failure are on the rise. The deeper the mine, the higher the stress level exerted on the surrounding rock. Heavier section profiles and optimising excavation shapes to endure higher stresses are developed for extremely difficult underground conditions.

Our qualified technical team are available for any information or advice concerning your unique project requirements.

Bernold Sheets & Lagging

Enhancing safety and efficiency throughout the mining process

Bernold Sheets are grooved, undulated, and bent to a certain radius, manufactured in sizes up to 2/3mm and 1080x1200mm long.

They act as a concrete framework when totally cured.

Sheets are assembled over the steel arches, overlapped and hooked up with pins. Each sheet will cover approximately 1m2.

Ribs provided within the sheets every 120mm are considered equivalent to a concrete framework structure.

The Bernold System provides more security, efficiency and is economical.
