Research on “Delayed” Dynamic Disaster Control Technology Based on Microseismic Monitoring

  • 摘要: 为了研究某矿N2105工作面采空区后方进风巷发生“滞后型”动力灾害的原因,首先分别从力学角度、顶板岩梁组合角度和地质角度对该工作面发生“滞后型”动力灾害的原因进行了分析,其次采用FLAC3D数值模拟软件对理论分析结果进行验证,最后建立微震监测系统作为N2105工作面动力灾害的控制技术手段。研究结果表明,采空区后方进风巷发生“滞后型”动力灾害是由构造应力、煤柱侧向支承应力和采场后方支承应力相互叠加共同作用的结果;采用微震监测技术可以实现三维、实时、连续的动力灾害监测和预警工作,可为矿井动力灾害防治工作提供一定的指导和帮助。
    Abstract: In order to study the cause of the "delayed" dynamic disaster occured in the intake airway behind the gob of N2105 working face in a coal mine,analysis was firstly conducted on the causes of the "delayed" dynamic disaster in this face from the angle of mechanics,roof rock girder theory and geological structure,then the theoretical analysis results were verified by using FLAC3D numerical simulation software,and finally,a microseismic monitoring system was established and used as a control technology for the dynamic disaster in N2105 working face.The results indicated that the "delayed" dynamic disaster occured in the intake airway behind the gob of the working face was resulted from the interaction of the tectonic stress,the side abutment stress of coal pillar and the bearing stress behind the working face;using microseismic monitoring technology could realize three-dimensional,real-time and continuous monitoring and early-warning of the dynamic disasters,which provided some guidance and help for controlling the dynamic disasters in other coal mines.
