摘要
为在矿井的整体状态中更好地突出分析矿井未确知矿压监测系统的功能和安全性,通过分析矿井未确知矿压监测系统中可能存在的各种未确定测度信息,遴选出可能影响矿井矿压监测功能和系统安全的各种相关影响因素,确定每一个矿井对矿压监测系统安全性评价的体系。首先,利用未确定测度理论和方法,对矿井矿压监测功能和系统安全性评价指标体系中的不确定测度信息进行了分析。运用层次分析法,得出各级测度评价指标的置信度和权重值;其次,运用未确定测度理论准确计算各级测度评价指标的置信度向量,从而得到了未识别或已识别的测度评价指标向量的函数;再次建立一个未确知测度分析的模型;最终依据未确知置信度向量识别的结果,确定每一个矿井对矿压监测系统安全性的置信度和评价指标等级,并将所构建的未确知模型广泛地应用于梅花井煤矿矿井的矿压监测评价系统。现场实践研究结果显示,利用该模型分析得出的安全性评价结果与实际现场情况相符。
To better emphasize the analysis of the overall status of the mine,particularly focusing on the functionality and safety of the mine's uncertain mine pressure monitoring system,various potential uncertain measurement information within the mine's uncertain mine pressure monitoring system was analyzed.The goal was to identify the influencing factors that might impact the functionality and safety of the mine pressure monitoring system.Each mine's evaluation system for the safety of the mine pressure monitoring system was determined.Initially,the uncertain measurement information in the evaluation index system of mine pressure monitoring function and system safety was analyzed using uncertain measurement theory and methods.The Analytic Hierarchy Process(AHP)was employed to establish the confidence and weight of each level of measurement evaluation index.Subsequently,accurate computation of the confidence vector for each level of measurement evaluation index was conducted using uncertain measurement theory,resulting in the identification of unidentified or identified measurement evaluation index vectors.This process led to the establishment of an uncertain measurement analysis model.Finally,based on the recognition of the uncertain confidence vector,the confidence level and evaluation index level for each mine regarding the safety of the mine pressure monitoring system were determined.The uncertain model constructed in this study was extensively applied in the mine pressure monitoring and evaluation system of the Meihuajing Coal Mine.Field research results demonstrated that the safety evaluation results obtained by using this model aligned with the actual on-site situation.
