【摘要】 针对平煤股份十一矿在进入深部开采期间多次发生强矿震的问题,根据SOS微震监测系统监测数据,应用地球物理学、地震学和岩石力学的理论与技术,研究微震事件震源物理、波动物理场、时空序列规律和时间域与空间域分布特征及其与采矿活动的关系,总结了十一矿微震活动规律,确定了4种矿震类型和原因,为防治冲击地压危险明确了方向。更多还原

【Abstract】 Strong tremors happened several times during deep mining in No.11 coal mine of Pingdingshan Tianan Mining Co.,Ltd.,causing serious potential hazard to the safety production.According to the data from the SOS microseism monitoring system,the applied earth geophysics,seismology and rock mechanics were used to study the tremor source physics,fluctuant physical field,laws of time-space series,distribution characteristics of time and space domain and their effects on mining actions.The microseism law was concluded,and four-type of tremors and their causes were determined,providing a scientific basis for the control of rock burst.更多还原
