In order to accurately evaluate stability of surrounding rock of roadway with weak intercalation, an improved analytic hierarchy process and criteria importance through inter-criteria correlation (CRITIC) method, were adopted to determine comprehensive weight, and unascertained measure theory (UM) was used to determine unascertained measurement vector. Furthermore, the set pair analysis theory (SPA) was introduced to optimize confidence evaluation process, and then a UM-SPA coupling analysis model was established and used to evaluate the stability of surrounding rock of the roadway with weak intercalation in some gold mine. The results show that in-situ stress, tensile strength and thickness of weak intercalation are the main factors influencing the stability of such kind of roadway. The set pair potentials of sections D4, D5, D6, D7, and D9 belong to micro-reversal potential and tend to be unsafe. The stability of roadway at different levels is in the following descending order: 290# level > 150# level > 90# level. The practical verification has proven that this model has an evaluation result consistent with the actual situation.
