Split Set-Friction Bolt-Zongxiang - Rock bolt

The split bolt is a new type of anchor that fully anchors the rock and actively strengthens the surrounding rock, its three-dimensional part is a longitudinally slit high-strength steel pipe, when installed in a drill hole that is slightly smaller than the pipe diameter, it can immediately apply radial pressure to the hole wall and prevent the surrounding rock from sliding down, together with the supporting force of the bolt tray Split set - Rock bolt - ZongxiangEvery kind of underground mine uses Split Set friction rock stabilisers for ground support. Miners also use them to pin mesh, hang conveyors, hold pipes and cables, secure rails in place, and for other needs.

Principles of rockbolting design - ScienceDirect

In shallow tunnels, or in the case of a small failure zone, the task of the rock support is to hold the loosened or failed rock blocks. Support layer 1, i.e. spot bolting or sparsely spaced pattern bolting, may be good enough to stabilise the rock mass (Fig. 6a). The bolts should be installed into the natural pressure arch behind the failure zone.Products - DSI Underground AustriaUnderground Solutions DYWI ® Drill Hollow Bar System Pre-Support Passive Support Drainage and Injection Rock Reinforcement Geotechnical Systems Anchor friction rock anchor bolt use for underground support Products - DSI Underground Rock bolt | mining | BritannicaRock bolt, in tunneling and underground mining, steel rod inserted in a hole drilled into the roof or walls of a rock formation to provide support to the roof or sides of the cavity.
