摘要: 为了确保矿山下山巷道的安全,防治下山诱发巷道蠕变型冲击地压,在坚持资源节约有效利用的原则下,研究了蠕变型巷道冲击的机理,探索了应力在线系统分析超前支承压力影响范围并结合微地震监测岩层破裂范围确定合理终采线的方法。采用该方法并结合山东滕东煤矿3下109工作面的应力监测数据及微地震监测数据,确定了3下109工作面合理的终采线位置。

Abstract: In order to ensure the safety of the mine downhill roadway, prevention and control of the mountain induced rock bursts, the creep deformation of roadway in insisting on the principle of saving effective utilization of resources, to study the creep deformation mechanism of the gateways, explores the stress system online analysis scope of abutment pressure and combined with the micro seismic monitoring rock rupture range to determine the reasonable mining line method. Based on the stress monitoring data and micro seismic data of 109 working surface of Shandong Tengdong coal mine, the reasonable stop-pick line position was determined.
