【摘要】 为预测深井矿山充填管道堵塞的难易程度,运用未确知测度理论,建立充填管道堵塞风险性评价模型。选取10项评价指标作为未确知测度模型的判别指标,根据实测数据建立各项指标的未确知测度函数,并利用信息熵理论获得各判别指标的权重,依照置信度识别准则进行等级判定,最后得到充填管道堵塞风险性预测值。研究结果表明:金川龙首矿、大红山铜矿、河东金矿和新城金矿等4个评价对象的风险性等级分别为:Ⅱ级、Ⅲ级、Ⅳ级和Ⅲ级。未确知测度理论能综合考虑各项评价指标对评价体系的影响,并进行相应的定量计算。更多还原

【Abstract】 For the sake of predictiong the risk of filling pipeline blocking of filling system in deep mine,a assessment model of filling pipeline blocking was built on the basis of the uncertainty measurement theory.Ten evaluation indexes were selected as the discriminant ones of the uncertainty measurement model.The uncertainty measurement function of each index was obtained based on the in-situ data.The information entropy theory was used to calculate the weight of each discriminant index,and the predictive value of filling pipeline blocking risk was finally achieved using the rules of credible recognition criteria.The results show that the four evaluation objects are Longshou mine of Jinchuan company,Dahongshan copper mine,Hedong gold mine,and Xincheng gold mine,and the risk grades of them are respectively Ⅱ,Ⅲ,Ⅳ,and Ⅲ.The influence of the evaluation indexes on evaluation system can be comprehensively considered by the uncertainty measurement theory,which is quantitatively calculated.更多还原
