摘要(Abstract)：
针对实际工程中评价爆破效果的因素指标不确定性问题,通过引入未确知测度理论,建立了基于未确知测度的爆破效果综合评价模型,并结合某露天铁矿深孔台阶爆破的实际情况,对爆破效果进行了基于未确知测度理论的综合评价。评价结果表明:基于未确知测度的爆破效果综合评价模型在各评价指标权重和识别准则的确定上,分别采用了信息熵和置信度识别准则,避免了模糊数学、层次分析法以及灰色关联理论等评判方法在这些方面的不足,使评价结果更具客观性;其评价指标可根据实际情况灵活选取,评价模型计算简单,评价结果能够为爆破工作者根据现场实际情况,适时调整爆破方案,为实现最优的爆破施工与管理提供决策依据。
In order to resolve the uncertainty problem of factor indicators of blasting effect evaluation for the actual project,the unascertained measure theory was introduced,and the comprehensive evaluation model of blasting effect based on the unascertained measure was built,then this model was used to evaluate the blasting effect of deep hole bench blasting in one open opit iron mine.The evaluation results show that the information entropy and confidence identifying criterion are respectively used to ascertain the evaluation index weight and identifying criterion in comprehensive evaluation model of the blasting effect based on unascertained measure,which avoided the shortcoming in other evaluation methods such as fuzzy mathematics,analytic hierarchy process as well as grey correlation and made the evaluation results more objective;and the evaluation index of the evaluation model can be selected flexibly according to actual situation and its calculation is simple,so the evaluation results can offer decision basis for blasting workers to adjust timely of blasting scheme according to the actual situation so as to achieve the optimal blasting working and management.
