Abstract
The presented procedure of slope stability analysis for open pits is based on the comprehensive studies into physical/mechanical properties and structural tectonics of pit wall rock mass with regard to jointing. The procedure is applied to find determine structural weakening and rock quality in Koktaszhal Open Pit Copper Mine in Kazakhstan.
