Description

Underground Mining Roof Support & Mining Roof Bolting Expansion Shell Rock Bolt Anchor

Description

The expansion shells are designed to be used for roof support in mining and tunneling areas (underground). Easy to use in conjunction with the corresponding threaded rod with a continuous coarse thread, anchor plate and anchor nut.

Expansion shells hold in any rock strata which is sufficiently competent to provide an adequate anchorage.
They are designed to anchor in soft ground or hard rock.
In good strata the anchorage exceeds the ultimate strength of the steel bolt.
All expansion shells require a competent strata in the anchor zone.
The suitability of the anchorage and the specific expansion shell to be used is best determined by physical load testing.
