The Westray Mine was a coal mine in Plymouth, Nova Scotia, Canada. Westray was owned and operated by Curragh Resources Incorporated (Curragh Inc.), which obtained both provincial and federal government money to open the mine, and supply local electrical power utilities with coal. It opened in September 1991, but closed eight months later when it was the site of an underground methane explosion on May 9, 1992, killing all 26 miners working underground at the time.
