Therefore, in order to introduce safer and more effective tendon support systems, the performance of tendon reinforcement has been assessed. In the main South African Collieries have relatively stable roofs compared to some of the other major coal mining countries. This is documented most clearly by the large cut-out distances that can be tolerated in many situations underground. However, there are situations in most, if not all South African coal mines where long tendon support is necessary. Long tendon support systems currently in use in South Africa were reviewed and a number of shortcomings identified. The objective of this project was to identify safer and more effective long tendon support systems suitable in South African coalmines. Appropriate test procedures for the evaluation of the performance of long tendon systems were also determined and are detailed in this report.enSIMRACSouth African coal minesTendon support systemsTendon technologiesCOL 704Conference PresentationAltounyan, P., & Clifford, B.
