摘　　要：针对现有煤巷围岩稳定性分类方案不能满足霍州矿区快速发展的机械化生产需求的现状,选取了巷道围岩强度、顶板岩体完整性、采动影响以及地应力等4个方面的9个指标,依据现场大量调研和统计的样本,采用基于模糊等价关系的聚类分析方法,研究了霍州矿区煤巷围岩稳定性分类方案,并对每类巷道围岩稳定性状况进行分析,提出相应的支护对策,制订出霍州矿区煤巷支护对策选择标准。To counter the condition that the existing stability classification scheme of coal roadway surrounding rock in Huozhou Coal Mining Area can not meet the rapid development of the mine＇s mechanized production,study was made on the stability classification scheme of coal roadway surrounding rock in this mining area by selecting nine parameters such as the strengthof coal roadway surrounding rock,the integrity of the roof rock,the mining impact and strata stress,according to a large amount of field survey and the statistical samples and by using the cluster analysis method which was based on the fuzzy equivalence relation,analysis was made on the stability of each kind of coal roadway surrounding rock,the corresponding support pattern was put forward,and the selection criteria for support patern of coal roadway in Huozhou Coal Mining Area was worked out.This research result can provide a certain basis for the support design,the construction and management of coal roadways in Huozhou Coal Mining Area.
