煤巷围岩稳定性分类指标确定研究

摘要

Based on the engineering geological conditions and production technology conditions of Huozhou coal electricity group limited liability company, this paper makes a deep analysis on the factors that impact the wall rock stability of the coal seam roadway, in this basis, by using analytic hierarchy process established the AHP model to determine the index of the coal seam roadway wall rock stability classification and extracted nine key index. Has very important significance to the study of the roadway wall rock stability classification.%以霍州煤电集团有限责任公司煤层巷道的具体工程地质条件和生产技术条件为背景,深入分析了影响煤层巷道围岩稳定性的诸多因素,在此基础上,运用层次分析法的基本原理,建立了煤层巷道围岩稳定分类指标确定的AHP分析模型,提取了9个关键指标.对于研究煤层巷道围岩稳定性分类具有十分重要的意义.
