Situation
El Teniente in Chile is the world largest underground copper mine. Due to
specific rock conditions, the risk of rock bursts is very high. Since security
standards at Codelco are amongst the highest worldwide, margins for failure
from rock bursts are very low. In the past, several rock bursts have affected
personnel and operations.
Description
To protect people and equipment at El Teniente, a combination of shotcrete with
MINAX® 65/4 and/or MINAX® 80/4 was used. This solution was successfully tested
at Geobrugg's dynamic test center in Walenstadt, Switzerland. Results were
above satisfactory.
In addtion to the MINAX® mesh, installation was completely mechanized with
®
®
Geobrugg's handler called, MESHA . MESHA increases safety and the efficiency
of the ground.
