【摘要】 针对老虎台矿区特厚煤层、断层构造较多、开采条件复杂等特点,通过应用微震分析法对83002工作面的导水裂缝带高度进行了研究。根据对微震事件分布规律,确定了83002工作面导水裂缝带高度,并应用现场可控源音频大地电磁法(CSAMT法)对其进行了验证,结果基本一致,可以确定所得上覆岩体导水裂缝带范围和高度的合理性,为后续开采的设计和安全防护提供了指导。更多还原

【Abstract】 Aiming at extremely thick coal-seam,abundant faults and complex mining conditions of Laohutai Colliery,micro-seismic monitoring system was applied to obtaining the height of water-induced fissure zone of 83002 mining face according to micro-seismic matters distribution rule.CSAMT was used to prove the height and range of water-induced fissure zone was rational.Micro-seismic method could provide reference for mining design and safety.更多还原
