Ground & Rock Tools
Rock bolting systems are used to stabilize excavated rock mass in underground mines and tunnelling. Rock bolts are systematically arranged to transfer the load from the unstable surface or exterior of the rock, to the much stronger interior part of the rock. The rock mass can be reinforced by different types of rock bolts. Atlas Copco offers two Rock bolting systems, the Swellex inflatable and expandable rock bolting system and the Roofex Energy absorbing and Monitoring rock bolts.
A Self-drilling anchor system is today's answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production. Atlas Copco MAI SDA self-drilling anchors provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.
