GROUNDSTABILITY IN SURFACE COAL MINES

This paper outlines potential problems, investigational requirements, stability evaluation requirements and construction control recommendations to maintain stability of highway slopes, pit floors, spoil piles and waste embankments. To illustrate typical problems and how to deal with them five case examples of stability on mining projects are discussed. The major subject areas discussed in the paper are highway stability and floor heave, tailing impoundments, and waste embankments. The case studies include a potential coal project in Western Canada, brown coal mining at the Morwell project in Australia, a tailing pond project for the Fording River Coal project in British Columbia, and an investigation of a waste dump below a strip mine that failed near Natal, British Columbia.
