摘　　要：本文应用层次分析法确定了影响复合顶板分类各因素的权值,并应用模糊数学方法对各因素建立了相应的模式识别模型。根据化处矿现场矿压观测资料及岩样试验数据,提出了化处矿7~#煤层复合顶板分类方案,为该矿的顶板管理、支护选择、采空区处理及支护强度的确定等提供了重要的参数和科学的依据。In this paper, the weight coefficients of the criteria whish affect the empound roof classification are determined by using the AHP method.(These criteria are unidirectional compression strength of rock, joint and fracture distance Ⅰ, lamination thickness h and first immediate roof caving interval L). And the model of pattern recognition of roof classification is established by using fuzzy mathematics theory. Based on the underground measurements and rock sample data, the classification program of the compound roof of the 7~# coal seam in Hua Zhu coal mine is proposed by using the AHP method and fuzzy mathematics theory. The results of the research have provided important techniques and the gob process in Hua Zhu coal mine.
