基于AHP-灰色聚类模型的采空区危险性分析研究

Underground goaf risk analysis evaluation based on AHP-grayclustering model

应用灰色系统理论的原理提出了采空区危险性分析的综合评价方法.从具体工程地质出发,分析了影响采空区危险性的诸多因素.通过层次分析法确定各指标的灰色聚类权值,根据实测数据确定了白化权函数,建立了灰色聚类综合评判模型,给出了灰色聚类系数和采空区危险性级别的对应关系,最终得出评价结果.应用该模型对贡北金矿10个采空区的危险性进行分析评价.研究结果表明:该方法与模糊综合评判具有高度的一致性,可以在工程实践中予以推广应用.

Comprehensive evaluation method of underground goaf risk was put forward with the principle of gray system theory.Several factors affecting goaf risk were analysed in light of engineering geological condition.According to practical data whitening function was ascertained and the comprehensive evaluation model of gray clustering was established.The final evaluation result shows that the correspondence of gray clustering coefficient and the rank of underground goaf risk is given.The risk evaluation method was employed in 10 goafs in Gongbei gold mine.The research shows the method is identical with fuzzy comprehensive evaluation and it can be applied to the actual engineering further.
