Principles of rockbolting design ScienceDirect

Jun 01, 2017· In South Africa, mine drifts excavated in high stress rock are typically supported with energy-absorbing rockbolts (e.g. cone bolts and Durabar) and ductile bolts (e.g. split set and cables). The primary bolting method is a ring of 1.2-m long bolts and the secondary bolting is a ring of 2.4-m long bolts plus lacing, meshing and 50 mm thick

Fatigue of Threaded Fasteners ASM International

torque is translated into increased fastener tension and clamping force. Guidance is provided with respect to the degree to which fasteners should be tightened. Bolts in tension should exert as much force on the joint as it and the joint members will stand[4]. A rule of thumb is to load the bolt to 60% of the material’s yield strength[5].
