Abstract: Entropy-weight fuzzy recognition model of buildings influenced by mining was put forward on the basis of diversity,fuzzy and weight unbalance characteristics of buildings damage by mining. Entropy-weight method was applied to determining weights of every influence factor by collecting study example data and setting up single-factor membership function. Fuzzy comprehensive membership of researching object was calculated by fuzzy mathematics theory,and then building damage degree was evaluated by maximum membership degree principle. Example analysis showed that evaluation result met with truth. This model comprehensively considered geology,mining condition and building status,and different weights of influence factors. Its arithmetic was simple and liable to realize,so its practical value was high.
