摘　　要：为了对顶板冒落机理进行研究,以蚕庄金矿为例,结合和谐度理论方法体系建立了顶板冒落因素综合评价模型,并基于模糊层次分析法确定了各指标因素权重。根据蚕庄金矿部分采场的单指标及多指标和谐度矩阵对其冒落易发性进行了综合评价。通过研究得出,蚕庄金矿采场稳定性等级6938采场处于非常稳定状态,7336采场与5307采场属于较稳定状态,可能发生冒顶现象,7808采场稳定性一般,冒顶几率相比前者均较大。研究结果与现场情况相吻合,由此证明和谐度评价方法具有一定的适用性,可以应用于顶板冒落综合评价体系。In order to study the roof caving mechanism,taking Canzhuang Gold Mine as an example,a comprehensive evaluation model of roof caving factors was established based on the harmony degree theory method system.And the weight of each index factor was determined based on fuzzy analytic hierarchy process.According to the harmony matrix with single index and multi indexes for parts of stopes in Canzhuang Gold Mine,the caving vulnerability was evaluated s comprehensively.Through the study,following results were concluded for the stope stability level in Canzhuang Gold Mine.No.6938 stope was in a very stable state,and No.7336 stope and No.5307 stope were in a relatively stable state,with a probability of roof caving.Moreover,compared with the former,No.7808 stope was in a common state of stability,with a relatively larger probability of roof caving.The study results were in a good agreement with the field situation,which proved that the evaluation method of the harmony degree had certain applicability and could be applied to the comprehensive evaluation system of roof caving.
