Abstract: According to the structure parameters, orebody occurrences and occurrence condition of steeply inclined medium thick orebody stope of a domestic copper mine, stability of roof, the side pillar and surrounding rock of 1′03 stope which is located at middle part of -445 m of this mine are analyzed by adopt Mathews stability graphical method. It provides reliable basis for design optimization of structure parameters of stope.

Key words: Mathews graphic method, Stability of stope, Structure parameters, Optimization
