基于证据理论的煤矿避难硐室可靠性等级划分

Classification Research of Reliabilityto Refuge Chamber in Coal Mine Based on Evidence Theory

首先建立了避难硐室的等级划分体系,确定了证据理论的理论模型;其次采用证据理论合成规则得出了避难硐室的可靠性等级,并采用德尔菲法确定因素权重和底层因素可信度分配值;最后结合某矿进行实例应用。结果表明:证据理论对于煤矿避难硐室可靠性等级的划分具有可行性和适用性。

First the classification system of refuge chamber was established,and identified with the theoretical model of evidence theory,then adopted the combination rules of evidence theory which reached the reliability grade for refuge chamber,and using the Delphi method to get the weights of factors and the underlying factors of reliability distribution value,combining with the application of mine. The results show that evidence theory is feasible and available for classification of coal mine refuge chamber reliability grade.
