Abstract:

The complicated conditions caused by a complicated geologic structure were analyzed by starting with the  Xuchang mine′s  complicated geologic structure. The deformation and failure of surrouning  rock masses characteristics and failure mechanism were analyzed combined with physical and mechanical characteristics of surrounding rock. Safety support technology measures were proposed under the condition of complicated geological structure and high stress. The results have important reference value to the design and construction of the same type engineering.

Key words: complicated geologic structure, high stress, surrounding rock, failure mechanism, roadway support
