Abstract:

In deep underground mines with high stress conditions, the rock mass behavior around openings can be complex and is difficult to quantify with current measurement methods. Selecting a proper combination of support elements to design a ground support system, can therefore be quite challenging. Several studies have been conducted in recent years to design ground support systems that provide adequate support to either hold or retain the rock under dynamic loading conditions. However, these studies have not been extensively used nor verified in mines. In practice, designing a support system requires a substantial amount of analysis and experience, but still might lead to variable designs from mine to mine that may in some cases be excessive and associated with high operating costs. This work presents a rockburst back analysis including seismicity, numerical modeling and underground observations.

Biography of the presenter: Yousef holds a PhD in mining induced seismicity from Queen’s University and a master’s from Laurentian University. Yousef joined Vale as a Ground Control specialist in 2019. During this time, he has been involved in various aspects of ground control engineering, seismicity and rock mechanics. Yousef has worked with seismic data from some of the deepest hard rock underground mines in the world. He worked as a Mining/Geotechnical specialist at ESG Solutions and his projects have included seismic array design, system optimization, seismic source parameter and hazard analyses and re-entry protocols. Yousef is the founder of TVSeminars Inc. TVSeminars is a platform for delivering online mining/geotechnical seminars.
