Hadi Nourizadeh, Ali Mirzaghorbanali, Naj Aziz, Kevin McDougall, Ali Akbar Sahebi, Development of a wireless system to measure the strain/deformation of rock bolts, Proceedings of the 2022 Resource Operators Conference, University of Wollongong - Mining Engineering, February 2022, University of Southern Queensland, 216-224.


In this study a smart set-up integrated with rock bolts was proposed to automatically monitor, record and analyse rock mass deformation. The proposed system which includes sensors and a wireless data acquisition system, rapidly and readily generates data sets along with customisable graphs, calculations and analysis in a cloud system and can be used in modern mining. To evaluate the developed technique, rock bolts were instrumented lengthwise using resistive strain gauges and then connected to the wireless data logger system. Elastic tensile tests as well as pull-out tests were conducted and the strain values along the rock bolts were successfully and accurately measured, recorded and uploaded to the cloud system.
