The coal bed gas permeability is reflected that the coal bed gas pulls out picks the development difficulty degree the crucial parameter. The development to the coal bed permeable evaluation study, according to the measure results proposed that enhances the coal bed permeable method, pulls out to the coal mine gas picks has the very realistic significance with the coal bed gas development, is topic which we are urgently needed study.This article has first analyzed our country coal mine safety form, then according to the research results and the supplement experiments, emphatically introduced the coal bed permeable each taxes. Using the Fuzzy Comprehensive Evaluation, determined that the coal bed permeability evaluating indicator system, has established indicator system's fuzzy appraisal evaluation collection, obtains various targets factor using the analytic hierarchy process the weight, then uses the fuzzy synthesis judgment the method, has established the permeable fuzzy synthesis judgment mathematical model. Using the mathematical model which obtains, the example has carried on the permeable fuzzy quality synthetic evaluation, and the Measure results and the actual result are Consistent.
