Modelling simulation of the performance of cable bolts in shear

Rasekh, Haleh and Mirza, Ali and Aziz, Naj and Nemcik, Jan and Li, Xuwei (2016) Modelling simulation of the performance of cable bolts in shear. In: 2016 Coal Operators' Conference, 10-12 Feb 2016, Wollongong, Australia.


The application of cable bolts as a secondary support system in coal mines has substantially increased over the last decades. This development emphasises a prerequisite for a better understanding of the mechanical behaviour of cable bolts in combination of shear and axial loads, which is of interest to geotechnical engineers and designers of underground structures. Based on various research studies undertaken, analytical models have been proposed to assess the shear performance of cable bolts with the aim of designing safe and sustainable rock structures. Recently, a shear strength model for cable bolts was proposed by Aziz et al., (2015). The model was based on Mohr-Coulomb failure criterion and the Fourier series concept. The proposed analytical model was associated with a set of systematic experimental studies by which model coefficients were calibrated. This paper compares the performance of a number of proposed mathematical models against the experimental data and presents a model that simulates the shear behaviour of cable bolts, which is in agreement with the experimental results.
