Abstract: The reasonable planning of mining strength based on anti-disturbance capacity of geological environment is a precondition to ensure harmonic development of resources exploitation and environmental protection.The anti-disturbance capacity of geological environment depends on tectonic setting elements which include structural medium,shape,fractures and tectonic stress,and is affected by groundwater.Thus the evaluation index system is established including quantitative index and qualitative index.Classification assessment on anti-disturbance capacity of geological environment is essentially a problem of fuzzy pattern recognition.The study application method of extension theory based on matter-element theory and extension set was used to transform contradiction problem into compatible.This method to process the qualitative index quantitatively and to express,the qualitative results quantitatively produced an ideal approach for accurate evaluation of anti-disturbance capability of geological environment in coal mining area.
