| 摘 要： | 长期以来，陷落柱一直严重威胁着我国北方一些煤矿的高产高效安全生产及综合机械化采煤机组的正常运行。地震勘探作为陷落柱勘探的主要技术手段，在识别查明该异常地质体方面发展挥了重要作用。以往利用地震时间剖面和层拉平切片对陷落柱进行识别解释，仅对较大的陷落柱（直径大于50 m）反映特征明显，而对于小陷柱却无能为力。通过分析陷落柱的地震正演模拟、属性特征及实例认为，可以利用方差体、均方根振幅、弧长等地震属性技术对其进行精细解释，效果较好。

| Abstract: | For a long time，the collapse column has been a serious threat to the high efficiency and safe production of some coal mines in northern China and the normal operation of integrated mechanized coal mining units.As one of the main exploration techniques，seismic exploration has played an important role in the identification of the anomalous geological bodies.In the past，seismic time profiles and strata leveling slices were used to identify and interpret subsided columns，and it can only respond to the larger collapse column（the diameter is greater than 50 m），there is nothing to be done for the small depression column.Through the analysis and study of seismic forward modeling，attribute characteristics and examples of subsided column，it was considered that the seismic attribute techniques such as variance volume，root mean square amplitude and arc length can be used to make a fine interpretation of subsided column，and the application effect was good. |
