将可靠性理论引入保护层开采技术应用中,归纳了7类影响保护层开采技术可靠性的主要因素,提出相应的评价指标,建立了由目标层,准则层和子准则层构成的可靠性评价体系。基于层次分析法基本理论,通过构造判断矩阵计算各层次指标重要性权重的方法,并根据计算结果,将各指标对系统可靠性影响的重要度分为4个层次。最后对现场实例进行了应用,对案例可靠性评价结果进行分析,其结果可对其他工程案例提供参考和借鉴。
This paper introduces the reliability theory into the application of protective layer mining technology, summarizes the seven main factors that affect the reliability of protective layer mining technology, puts forward the corresponding evaluation indexes and establishes the reliability evaluation system composed of target layer, criterion layer and sub-criterion layer . Based on the basic theory of analytic hierarchy process (AHP), a method of calculating the importance weight of indicators at all levels is constructed by constructing a judgment matrix. According to the calculation results, the importance of each index on system reliability is divided into four levels. Finally, the field examples are applied to analyze the results of the case reliability evaluation, the results can provide reference and reference for other engineering cases.
