摘　　要：煤炭行业在我国国民经济中起着举足轻重的作用,煤炭成为国家能源安全的重要保障。在井下开采过程中,随着深度的不断增加,巷道围岩分析与控制成为重点工作。以AHP分析法为基础,建立了由9种因素构成的评价体系,并对该体系进行了数学分析,为巷道围岩控制的决策提供定性和定量分析结果。同时,以分析结果为依据,针对重点因素制定相应措施,特别是改善了支护质量,有效提高了煤峪口矿81020工作面围岩稳定性,为井下生产带来了保障。The coal industry plays an important role in China's national economy,and coal becomes an important guarantee of national energy security.In the process of underground mining,with the increas⁃ing depth,the analysis and control of roadway surrounding rock become the key work.Based on AHP analy⁃sis method,this paper establishes an evaluation system consisting of nine factors,and makes a mathemati⁃cal analysis of this system,providing qualitative and quantitative analysis results for the decision-making of roadway surrounding rock control.At the same time,based on the analysis results,corresponding measures are formulated according to the key factors.In particular,the quality of support is improved,and the stabili⁃ty of surrounding rock of 81020 working face of Meiyukou Mine is effectively improved,which guarantees the underground production.
