摘　　要：以金源煤矿深部采区边界的大屯断层煤柱宽度留设为背景,采用理论分析结合数值模拟等研究方法,建立了断层失稳滑移力学模型,对比不同煤柱宽度条件下的断层煤柱稳定性。结果表明:避免开采条件下煤柱失稳及断层活化,合理的断层煤柱宽度为100 m,煤柱宽度设计结果符合相关要求。Taking the setting of Datun fault coal pillar width at the boundary of deep mining area in Jinyuan Coal Mine as the background,a mechanical model of fault instability and slip is established by means of theoretical analysis and numerical simulation,and the stability of fault pillar under different coal pillar width conditions is compared.The results show that to avoid coal pillar instability and fault activation under mining conditions,the reasonable width of fault coal pillar is 100 m,and the design results of coal pillar width meet the relevant requirements.
