基于Fuzzy模型的矿井通风系统风流稳定性评判

Judgment on Air Current Stability of Mine Ventilation System Base on Fuzzy Model

针对矿井通风系统具有复杂、多变、随机等内涵明确、外延模糊的特点,在研究其稳定性相关基础上应用Fuzzy数学的方法对诸多因素进行综合判定。根据矿井通风系统风流稳定性所涉及的范围,本着科学、可测、可操作的原则建立了评价指标集合,采用了层次分析法确定权重,通过根据调查划分出不同评判等级并给出了Fuzzy判定模型和解算方法,为分级管理提供了科学依据,为正确指导现场生产打下基础。

According to the mine ventilation system with the complicated,variation,random,and the intension clear and extension fuzzy features,base on the study on the related stability,the Fuzzy mathematics method was applied to the comprehensive judgment on many factors.According to the scope related to the air current stability of the mine ventilation system,with the science,predictable and operational principle,a evaluation index integration was established.The AHP was applied to set up the weight.The different judgment grading classified from the investigation and the Fuzzy judgment model and resolution method provided could provide the scientific basis foe the grading management and the base to correctly guide the site production.
