A New Criterion on Designing an Effective Cable Bolt Length Subject to Static Loading in Underground Excavations
Author(s): Fhatuwani Sengani*
A simple probability analysis failure criterion for cable bolts in underground excavation is described. The criterion was developed using static
loading tests of mechanical anchors (38 tons, 18 mm diameter cable, 2 m length and six strands), and Finite Element Method. Three static
loading tests were performed, thereafter, an underground excavation was simulated with several wedges wherein the effectiveness of the bolt was
tested in varying spacing, while other parameters remaining constant. A simple probability criterion was therefore developed to bridge the gap on
identifying effective bolt length and total effective length of the bolts within the excavation in varying strata control (change in angle of the strata
and change in thickness of the strata). The criterion is suitable for predicting the effective bolt length, predicting the total effective bolts length .. Read More»
