Abstract:
      The concept of engineering geology stability zone classification used in rock soil engineering on earth was introduced to stability analysis for surrounding rocks of underground engineering of mine in the paper Based on analysis on conditions influencing surrounding rock stability,various elements considered are determined and quantified from practical circumstance of Meishan Iron Mine Dynamics classification method of Fuzzy cluster is briefly described Based on statistics of 1370 specimens from Meishan Iron Mine,stability zone classification of engineering geology of surrounding rocks at Meishan Iron Mine is done with dynamics classification of Fuzzy cluster Result of grades for Fuzzy dynamics classification is compared with result for RMR classification method Stability classification result of surrounding rocks in deeper underground region of Meishan Iron Mine is given finally
