Mechanical Anchors Resin and Rebar Rock Bolts

Anchors and rock bolts which are commonly assigned the general term rock bolts are used for rock reinforcement in Mining and Tunneling Rock bolts limit the loosening of blocks out of the rock mass and shear displacements Furthermore the frictional force between individual rock layers is increased Anchors with a variable anchor length enable pre tensioning and thus an active force

Rock bolt load analysis and monitoring Mining3

Rock bolts are generally exposed to a combination of shear bending and tension that can cause the bolt to deform with increasing joint displacement potentially leading to failure In spite of these combined effects only tensile capacity is currently considered in design and testing Adding to this design oversight tensile capacity isn t the weakest performance link Shear capacity on
