煤层顶板稳定性智能分区实现及工程应用

针对目前煤层顶板分类方法存在计算量大、人工参与多、智能化程度低，为煤矿生产不能提供快速指导的问题，结合煤矿现场实际情况，确定了煤层顶板稳定性的影响因素。以层次分析和模糊聚类为理论核心，建立了煤层顶板稳定性层次分析模型，得出了影响因素的隶属度和合成运算方法。以Visual Basic 6.0为编译环境，将Matlab与Surfer进行二次混合编程，对钻孔数据以及地质资料进行分析整理，自动绘制煤层顶板稳定性类型分区图，形成煤层顶板稳定性智能预测分区系统。将研究成果应用于贺西煤矿3号煤层顶板稳定的预测，通过钻孔窥视对预测结果进行了验证。

Realization and engineering application of classification of coal roof stability

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.
