Abstract: The paper introduced the basic theory and method of triangular fuzzy number,and established an evaluation indexes system of safety production comprehensive quality of miner based on triangular fuzzy number.By appling the evaluation indexes system to evaluate safety production comprehensive quality of miner quantitatively and comprehensively,the relative weights of various factors of evaluation indexes of safety production comprehensive quality of miner were known as W′_1>W′_4>W′_7>W′_6>W′_KG-*25>W′_2>W′_3,namely that the security responsibility and correcting skills of miners were the most important indexes.The method overcomes the limitation of the method named analytic hierarchy process,and accords with fuzziness of human knowledge, which can reduce personal subjective unilateralism and enhance believability of weight of evaluation indexes.
