John Whittall, M.A.Sc., P.Eng. (BC, ON, AB), specializes in rock slope engineering, landslide runout and risk reduction at operating mines, natural rock slopes and rock storage facilities. John’s typical projects involve stability assessments, slope performance monitoring and empirical and numerical runout assessments for pit slope failures, rockfill failures and natural landslides. John developed the pit slope runout tools implemented in the mining industry and quantitative risk assessment techniques to define exclusion zones and assess the safety implications of a slope. John has also led several projects to integrate natural and mined hazards into mining clients’ risk frameworks for exploration projects and has designed and monitored construction for various landslide barriers.
