摘要
采用高精度微震监测技术,结合现场支架阻力观测,对大采高综放开采顶板活动规律进行了研究。研究表明:微震事件的频次和能量具有明显的周期性,微震事件在高度上的动态发展规律反映出大采高综放顶板来压存在大小周期现象,且这种现象与工作面宏观观测得到的周期来压具有一致性;根据微震监测和支架阻力观测结果得出大采高综放开采顶板为"悬臂梁-铰接岩梁"结构。
Applying two methods of high-precision micro-seismic monitoring system and spot hydraulic support resistance observation,the mechanics of roof strata in long wall with top coal caving with great mining height was studied.The results show that the frequency and energy of micro-seismic events appears as periodicity obviously;the dynamic development regularity in height of micro-seismic events reflects that roof strata weighting of long wall with top coal caving with great mining height presented as large-small periodicity,which is consistent with periodical weighting observed on the working face.According to the results of micro-seismic monitoring and stents resistance observation,it could be concluded that the roof of long wall with top coal caving with great mining height appears as structure of "cantilever beam-articulated rock beam".
