摘　　要：西石门铁矿回采巷道围岩变形破坏严重,破坏形式复杂。影响回采巷道围岩稳定性的主要因素是岩石强度、地应力、岩体完整性、采动影响等,以这些因素为分类指标,根据模糊聚类分析原理,采用VB6.0语言建立分类程序,把西石门铁矿回采巷道围岩分为非常稳定,稳定,一般稳定,不稳定和极不稳定等5类。针对不同类别的巷道围岩分别提出相应的支护方案。The wall rock of mining roadway in Xishimen Iron Ore Mine was seriously deformed and broken in complex forms. Based on a site investigation, the main factors influencing the wall rock stability were found and taken as indicators in the classification of the wall rocks of mining roadways in Xishimen Iron Ore made by a program in VB6.0 and based on fuzzy clustering. Based on this classification of wall rocks, the support methods for the mining roadways were studied and support plans for different wall rocks proposed.
