中文摘要：
为研究金属矿山软岩巷道顶板破坏因素影响关系及机理,建立了一种有效处理分析模型,为巷道顶板稳定防治安保提供有效帮助。模型利用粗糙集原理结合了经标度化和权重化方法改进后的灰色关联分析方法,其使用粗糙集原理对各种影响因素进行预处理,得到系统核心因素及权重,使用改进后的灰色关联方法对顶板位移破坏机理进行主观和客观、定性和定量的整体灰色综合分析。模型的使用结果得到了各因素对顶板破坏的影响和关联关系,以及有关巷道顶板破坏防治的有用信息。实际结果表明模型可靠有效。
英文摘要：
In order to study the failure mechanism of soft rock roof in mines and the relation among the failure factors,an effective model was established,which can benefit roof stability control.The model combined the rough set theory with the grey relation analysis method improved by using conversion and weight scale method.The model preprocessed various failure factors to obtain the core elements and their weights with the rough set theory.The mechanism of roof failure were analyzed with the improved method in subjective and objective,qualitative and quantitative ways.The results show the relation of factors associated with roof failure,and provide a reliable basis to control roof damage.Actual results show that the model is reliable and effective.
