| Abstract |
Fully encapsulated tendons and rockbolts provide safe and effective reinforcement for the relatively deep coal mines in weak strata generally worked in Europe. However, once a fully grouted tendon and rockbolt system has been installed, there is no way of determining whether it remains intact. Reinforced roadways also suffer the risk of deterioration over time and gate roadway stability can be jeopardized in the area of enhanced stress near the retreating/advancing face. If rockbolting is going to fulfill its potential for transforming European coal mining, appropriate instrumentation and strategies need to be developed to overcome these problems. This report presents work leading to a proposed integrated strategy including the in situ testing of the integrity of reinforcing tendons and grout, quality management, improved instrumentation and practical risk assessment procedures. |
