孤岛工作面矿震活动规律分析OA
Analysis of isolated working face of mine earthquake activities rules
针对鲍店煤矿103上02工作面（孤岛工作面）依据微震监测系统所监测到的矿震活动，分析开采期间微震事件的时空分布规律。研究认为，震动频次随日推进速度和开采强度的变化而变化，变化趋势基本上一致；基本顶的周期性垮落和巨厚红层结构运动是强矿震事件发生的主要原因。
Aiming at 103 02 working face (isolated working face) of Baodian coal mine, on the basis of mine earthquake activities of microseismic monitoring system monitoring, analysis of the spatial and temporal distribution of microseismic events during mining. Research showed that the vibration frequency change with advancing speed and mining strength, the change trend is basically consistent; the periodic caving of the basic roof and the structure movement of the e…查看全部>>
