Abstract: For the fuzzy math，gray theory，the identical degree of set pair analysis method used in stope mining quality evaluation，could not orderly divide evaluation space，the subjective largely impacts the determined weights，using unascertained theoretical constructed stope mining unascertained comprehensive evaluation model，realized accurately，objectively evaluate the merits of stope mining quality.Using CMS detection technology and SURPAC visualization tools，accurately obtained the stope mining dilution rate and loss rate technical indicators，using stope mining economic indicators provided by mine information systems，constructed a evaluation index system to comprehensively reflect the quality of stope mining.10 stopes of a copper mine were evaluated by using the constructed evaluation model.The results showed that the model used to evaluate the quality of stope mining was effective，the evaluation results were in line with the actual mining.
