CRR 370/2001 Performance tests for stranded ground reinforcement in mines

Stranded reinforcement tendons have become more commonly used in UK coal mines in conjunction with rockbolt reinforcement. Describes a project which attempted to achieve a better understanding of reinforcement mechanisms mobilised by these stranded tendons, as opposed to conventional rockbolts. Research areas included: integrity testing; instrumentation for integrity testing and load measurement; alternative extensometry; laboratory pull testing and in-situ pull testing. Concludes that the measurement, testing and consequently the understanding of stranded tendon reinforcement has been brought significantly nearer to that of conventional rockbolts.
