QUANTITATIVE EVALUATION ON GEOLOGICAL STRUCTURE COMPLEXITY OF CUIJIAZHAI MINE,HEBEI PROVINCE

The quantitative evaluation on geological structure complexity is one of the hotspots in the research of mining geology,the key techniques of which include selecting proper assessment indexes and assessment models.On the basis of analysis of geological setting and procession of exploration data,5 continuous deformation parameters and 5 discontinuous deformation parameters are taken as indexes for the evaluation on geological structure complexity.The comprehensive statistical assessment model and comprehensive fuzzy assessment model are both adapted for the quantitative evaluation on geological structure complexity of Cuijiazhai mine,Hebei Province.A comparative study shows that both can be used for quantitative evaluation on geological structure complexity,with the fuzzy model being more plausible.
