Rock Bolting is necessary for many rockfall and containment systems, as drilling is needed to incorporate the anchor and or bolts into the rock to maintain the integrity of the system.
Specialised equipment and experienced staff are critical in identifying just exactly where and how rock bolting is required.
Civil construction and Mining processes can cause fracturing and shearing resulting from the stress and distribution of materials. This causes weakness in the rock mass/ formation which presents a number of serious hazards.
Rock bolting systematically transfers the load from the unstable surface or exterior of the rock face to the strong intact interior of the rock mass. The process consists of drilling through the unstable section of rock at the exterior of the location, then securing a stabilising bolt into the more secure material toward the base or core of the area.
Holes usually vary from 25mm to 150mm and thorough planning and experience is essential in correctly identifying which part of the rock is the strongest and which is the weakest point, before the careful execution of the task to eliminate the possibility of rocks cracking and dislodging.
This technique is particularly useful for areas with difficult access, where other methods are unable to be used.
Common tasks requiring rock bolting include:
- Bolting Unstable Rock formations
- Infrastructure Protection
- Foundation Support
- Bridge Construction
- Rail Cutting Reinforcement
- Portal Entries
