Design flaws Geotechnical experts locate the underlying cause of Mount Polley tailings breach

摘要

A three-person investigative panel appointed by the government of British Columbia reported in January that a design flaw was responsible for the Mount Polley tailings dam breach in August 2014. The geotechnical experts - Norbert Morgenstern, professor emeritus of civil engineering at the University of Alberta; Steven Vick, a geotechnical engineer and review consultant; and Dirk Van Zyl, a professor of mining engineering at UBC - also issued recommendations to improve future tailings storage facility (TSF) designs, all of which the province pledged to adopt.
