针对目前煤层顶板稳定性分类计算量大、劳动强度大、智能化程度低等问题，结合煤矿实际情况，给出了影响顶板稳定性的决定因素。以层次分析法和模糊聚类法为核心，建立了煤层顶板稳定性层次分析模型，得出了各影响因素的隶属度和综合运算方法。以Visual Basic 6.0为编译环境，利用MatLab和Surfer进行二次混合编程，建立了煤层顶板稳定性的层次分析模型。通过对钻孔资料和地质资料的分析，绘制出煤层顶板稳定性分区图，形成分区系统，并将研究成果应用于河西煤矿3号煤层，通过钻孔观测对预测结果进行了验证。
The present classifications of coal roof stability have many problems,such as large amount of calculation,too much human labor and low degree of intelligence,which cannot provide guidance for mine production.Based on the real sitution in coal mine,authors gave determining factors to coal roof stability.Using Analytic Hierarchy Process and Fuzzy Clustering Method as its core,established the coal seam roof stability hierarchical analysis model and concluded the membership of the influence factors and synthetic operation method.With Visual Basic 6.0 for compilation environment,used Matlab and Surfer to make secondary mixed programming,Analysed the drilling data and geological data and draw partition map of coal roof stability to form partition system.Applied the research results to No.3 coal seam of Hexi Coal Mine and validated the prediction by observing the drilling.
