摘要:
为了定量表征回采工作面不同开采阶段冲击危险区动态演化过程,以某煤矿22307回采工作面被动CT反演工业试验为研究背景,采用理论分析、现场监测及工业试验等方法,开展考虑区域波速异常系数的冲击危险区动态演化研究,提出区域波速异常系数概念,构建基于区域波速异常系数的冲击危险区动态评价方法并开展现场应用。研究结果表明:区域波速异常系数SC可定量评价目标工作面不同开采阶段冲击危险区分布的均匀性变化,某煤矿22307回采工作面3个不同推采阶段平均区域波速异常系数分别为0.049,0.051,0.070,整体呈现上升趋势,动态评价结果与基于多因素耦合的冲击危险区分析高度吻合,与现场实际基本一致;提出“长短钻孔交替卸压+常规预卸压措施+被动CT反演常探测+增强主被动支护措施”的针对性防冲措施。研究结果通过现场施工验证,能够为相似工况提供一定的理论参考意义。
Abstract:
In order to quantitatively characterize the dynamic evolution of rockburst hazard zones at different mining stages of a longwall working face,an industrial test of passive CT inversion conducted at the 22307 mining face of a coal mine is taken as the research background.Methods including theoretical analysis,field monitoring,and industrial testing are adopted to investigate the dynamic evolution of rockburst hazard zones considering the regional wave velocity anomaly coefficient.The concept of the regional wave velocity anomaly coefficient is proposed,and a dynamic evaluation method for rockburst hazard zones based on this coefficient is established and applied in field practice.The results indicate that the regional wave velocity anomaly coefficient (SC) is used to quantitatively evaluate the variation in the uniformity of rockburst hazard zone distribution at different mining stages of the target working face.The average values of SC at three different advancing stages of the 22307 mining face are 0.049,0.051,and 0.070,respectively,showing an overall increasing trend.The dynamic evaluation results are found to be highly consistent with the rockburst hazard analysis based on multi-factor coupling and are in good agreement with field observations.Furthermore,a targeted rockburst prevention strategy is proposed,including “alternating pressure relief by long and short boreholes,conventional pre-relief measures,regular detection using passive CT inversion,and enhanced combined active and passive support measures.” The research results are verified through field implementation and are considered to provide a theoretical reference for similar engineering conditions.
