Ben Thompson

Senior Geomechanics Specialist

PhD in Rock Physics, 2006 MESci Geophysics and Geology, 2001 University of Liverpool

Ben joined Paterson & Cooke in 2022 and is based out of our Sudbury, Canada office. As a senior geomechanics specialist, Ben has led numerous barricade design and backfill strength consulting projects. He has also collaborated with academic partners in these areas to advance the State of Best Practice. He is a keen advocate of the use of instrumentation to optimise safe and efficient backfilling.

Ben led backfill instrumentation fieldwork campaigns during an international paste research project in 2007-2010, and subsequently modified these approaches for the challenging production environment on a consulting basis. His underground experience and pragmatism, necessary in adapting research-oriented fieldwork to the needs of the operations environment, adds significant value to consulting projects.

In addition, his Rock Physics PhD and Rock Mechanics background allows Ben to offer a perspective grounded in the fundamental need for backfill to fulfil the geotechnical demands of the mining environment.
