Mr. Stone has 20 years of international experience, including mine site operations and as a rock mechanics consultant in the mining and civil infrastructure industries. His area of interest includes ground support assessment and design in complex geotechnical environments with particular focus on deep underground excavations and open pit slope design. He also demonstrates considerable experience in infrastructure tunnel design, deep shaft design, and mine subsidence assessments. His geotechnical advice for tunnel excavation is namely in the form of ground support systems, excavation layout and sequencing, ground monitoring, ground characterization, and ground support audits. His experience in open pit slope design includes rock mass characterization and structure analysis for geotechnical models, domain characterization, design in the form of bench configurations, inter-ramp angles, and overall slope and stability analysis. He is a chartered professional engineer for both geotechnical and civil engineering in Australia.
