高原矿井风机在矿产资源的开采过程中发挥着极其重要的作用，开展矿井风机状态评估对促进矿井风机安全管理具有十分重要的现实意义。针对高原矿井所处环境的复杂性，构建了高原矿井风机评估指标体系。利用不确定性区间层次分析法和集对分析理论中的三元联系数精确地计算了高原矿井风机指标权重，在此基础上，构建了五元联同异反评估模型对矿井风机进行了静态评估；此外，引入偏联系数理论对矿井风机未来的运行状态进行了预测和评估，从而实现了矿井风机静态和动态评估的目的。最后以云南省某金属矿井风机为例，验证了该方法的适用性和有效性。

Mine fans at high altitude region plays an extremely important role in the mining process of mineral resources.The mine fans provide a guarantee for the safe mining of mineral resources by providing fresh air and eliminating toxic and harmful gases，so they are an important part of safe production.It is of great practical significance to carry out a scientific assessment of the operation status of mine fans to promote the safety management of mine fans. In view of the complexity of the environment in which plateau mines are located，the mine fans evaluation index system was constructed，including one overall objective，four middle factors and sixteen criteria. Due to the uncertainty in the calculation process of the index weights，the weighted interval was calculated using the analytic hierarchy process （IAHP）. In order to obtain the accurate index weights，the 3-element connection number was used to convert the interval weights into accurate weights.Therefore，the uncertainty in the process of obtaining index weights can be effectively resolved，making the index weights more reasonable. In addition，the establishment of five-element identical-discrepancy-contrary evaluation model realizes the purpose of static assessment of the mine fan.The partial connection number theory in the set pair theory is introduced to predict and evaluate the operation state of the mine fan.Thereby realizing the static and dynamic evaluation for fans at high altitude region.The operation status of the mine fans is evaluated from the static and dynamic dimensions，making the evaluation results more practical.Finally，an example of a mine fan in Yunnan Province was introduced to verify the applicability and effectiveness of the method.The evaluation result of the operation state of the mine fans is medium level. In addition，the operation state of the mine fans was analyzed using partial connection number.Therefore，the future development trend of the indicators of mine fans can be predicted.The analysis results show that these indicators，namely environmental humidity，external structure status and personnel’s physical condition，will decline sharply in the future.Therefore，those should be classified as high risk factors，and corresponding management measures and technical measures should be proposed to improve the operation status of the fan.The evaluation results provide an important reference for the safety management of mine fans in the plateau area，and can effectively prevent the accidents caused by the poor operation of mine fans.Therefore，the method proposed can be used to evaluate the status of mine fans in the plateau area，which can not only grasp the current operation status of the fan，but also predict the development trend of the future status of the fan.The targeted suggestions for fault diagnosis，risk management and optimization of mine fans in the plateau area can be put forward.
