基于微震的采空区稳定性分级研究
|
摘要
为监测潘洛铁矿采空区稳定性,预测并防治采空区失稳导致的灾害,结合潘洛铁矿引进的IMS微震监测系统,对其台网误差进行了调试与反演,并统计与分析了矿井尺度的微震活动性特征。同时将主要采空区进行了有效分区,并对各分区的微震频次、能量、时间序列、βn分布、η值、CUFIT模型等特征进行了分析,最后结合采空区分级标准对各分区综合分级,为现场采空区稳定性监测提供参考与依据。
IMS microseismic monitoring system was introduced for monitoring the stability of goaf in Panluo Iron Mine,so as to forecast and prevent the hazard brought by goaf instability.The error debugging and seismic inversion were then completed for the seismological observation network.Based on the analysis of characteristic of microseismic activities,the main goafs were divided into four regions,for which the MS parameters including microseismic frequency,energy,time series,βndistribution,η value,CUFIT model,were all analyzed.Finally,each region was comprehensively graded using the goaf's grading standard according to the characteristic of MS data.It can provide a reference and basis for the monitoring of goaf's stability on site.
