摘要
针对霍州煤电集团下属矿区岩石巷道工程地质与生产技术条件,选取了岩体强度、岩体完整性系数、地下水状态、水平最大主应力、水平最大主应力方向与巷道夹角以及巷道埋深等6个稳定性评价指标,依据大量的现场调研样本,采用模糊聚类分析方法,研究了霍州矿区岩石巷道围岩稳定性分类方案,并在此基础上针对每类巷道的围岩稳定性状况提出了相应的支护对策。研究成果为霍州矿区岩石巷道支护设计、施工和管理提供了一定的依据。
Based on the geological conditions and technical conditions in Huozhou coal mine,six indexes for evaluating the stability of rock roadway including rock strength,rock integrity,ground water status,maximum horizontal principle stress,the angle between the direction of maximum horizontal principle stress and roadway axial direction and the depth of roadway are proposed.Then,Fuzzy Clustering Method is employed to investigate the evaluation of the stability of rock roadway including rock strength according to numerous survey and statistical samples.Finally,the supporting measures for the roadways under the different stability status are put forward.The results provide some basis for the design,construction and management of the rock roadway in Huozhou coal mine.
