摘　　要：文章以某矿工作面作为研究背景,通过理论分析揭示煤岩体破碎过程中的能量耗散机理,并系统地探讨冲击地压的影响因素以及冲击倾向性的评价方法。在此基础上,提出了窄煤柱的防冲措施,并通过建立煤柱的弹塑性模型设计煤柱留设方案,随后对方案进行优化,同时确定合理的煤柱宽度。通过采用FLAC 3D数值模拟分析不同宽度煤柱的应力分布特征,并对巷道的稳定性进行了深入探讨。This paper takes the working face in a certain coal mine as the research background,reveals the energy dissipation mechanism in the fragmentation process of coal and rock masses through theoretical analysis,and systematically explores the influencing factors of rock bursts and the evaluation method of rock burst tendency.Based on this,it proposes impact prevention measures for narrow coal pillars,designs the coal pillar retention scheme by establishing the elastic-plastic model of coal pillars,optimizes the scheme subsequently and determines the reasonable width of the coal pillars simultaneously.By using FLAC 3D numerical simulation,it analyzes the stress distribution characteristics of coal pillars with different widths and conducts an in-depth discussion on the stability of the roadway.
