用小波分析理论研究采矿速度与矿震的关系
|
摘要
矿震主要受开采活动、矿山所处构造环境及区域构造应力场的影响。应用小波多分辨率分析发现,开采速度与矿震发生有很强的联系性和相关性,证实了通过控制开采速度可减少矿震发生的观点,论证了应用开采速度曲线预测矿震的可行性,并给出了具体的预测数据。实验表明,慢匀速开采能有效地减少矿震发生的次数。
Mine-induced seismicity is mainly affected by the mining activities and the structural environment as well as the regional structure stress field where the mine is located.Applying wavelet multiresolution analysis we found that there is very strong relationship between mining speed and mine-induced seismicity.On the basis of this relationship,we proposed controlling the mining speed to reduce mine-induced seismicity.The feasibility of using the mining velocity curve to forecast mine-induced seismicity is analyzed with concrete forecast data.Experiment shows that with a slower and uniform mining speed the mine-induced seismicity can be reduced effectively.
