基于地震CT透射技术的工作面冲击危险性探测技术
Rock-burst Danger Prediction of Mining Face Based on Seismic CT Transmission Technology
【摘要】 利用地震CT技术在25110工作面前方242m范围内进行地质探测,采用相关软件进行数据分析,得出了地震波纵波波速反演图像,结合现场地质和开采等条件,对地震波纵波波速反演图像进行了合理的解释,划分出了6个异常区,并针对不同类型的异常区提出了相应的防治措施。
【Abstract】 Applying seismic CT technology to exploring 242m in front of 25110 Mining Face,inversion map of seismic longitudinal wave velocity was obtained by data processing.6 stress-abnormal areas were partitioned by explaining the map on the basis of analyzing geological and mining conditions.Prevention measures for every stress-abnormal area were put forward.
