Abstract: Through site investigation on cranny found in west of Jinduicheng open-pit mine and collect and arrange and comprehensive analysis on monitoring data of a long term, key fracture zone area which effected stability of west of stope was the northwest corner and central of west was confirmed and divided, through analysis of deep deformation monitoring data and simple observing point data, found out main factors which effect stability of slope, finally suggested to adopt necessary measures to remove hidden dangers, made sure stability of final permanent slope of the west and safety of mine production.

Key words: Fracture, Fault, Stability of slope
