摘　　要：针对亭南煤矿深部盘区非对称大巷煤柱区域冲击地压防治问题,采用理论分析、数值模拟、现场实践等方法对大巷煤柱区煤柱稳定性、覆岩破断规律及不同采空状态下煤柱区应力分布特征进行分析,揭示大巷煤柱区煤体失稳冲击地压发生机理,制定了煤柱区外围工作面停采区域卸压方案并用于现场实践,对防治效果进行检验。研究结果表明,大巷煤柱外围垂直应力随工作面采空持续升高,应力增量逐渐减小。通过防冲方案的实施,现场工程实践显示大巷煤柱区域顶板深孔爆破卸压提前释放了能量,易诱发冲击地压的大能量事件减少,为指导深部盘区非对称大巷煤柱区域冲击地压防治提供借鉴。In response to the prevention and control of rockburst in the asymmetric coal pillar area of the deep panel area of Tingnan coal mine,theoretical analysis,numerical simulation,on-site practice and other methods were used to analyze the stability of the coal pillar in the main roadway coal pillar area,the law of overlying rock fracture,and the stress distribution characteristics of the coal pillar area under different goaf states.The mechanism of rockburst caused by the instability of the coal body in the main roadway coal pillar area was revealed,and a pressure relief plan for the peripheral working face of the coal pillar area was developed and used for on-site practice to verify the effectiveness of prevention and control.The research results indicate that the vertical stress around the coal pillar in the main roadway continues to increase with the goaf of the working face,and the stress increment gradually decreases.Through the implementation of the anti impact plan,on-site engineering practice has shown that the deep hole blasting unloading of the roof in the coal pillar area of the main roadway releases energy in advance,reducing the occurrence of high-energy events that are prone to inducing rockburst.This provides a reference for guiding the prevention and control of rockburst in the asymmetric coal pillar area of the deep panel area of the main roadway.
