摘要
通常情况下,较小规模陷落柱的地震响应特征不明显。运用矩阵的奇异值分解(SVD)方法,通过对三维模型数据的处理,把煤层反射波作为被压制的对象,突出断陷点所产生的绕射波,以达到提高对较小规模陷落柱地震解释的目的。实际运用效果较好。
In the common situation, the seismic response of small scale karst collapse eolumn（KCC） is not obvious. This paper utilizes the SVD method to process 3D modeling data. The reflection wave of coal layer has been filtered, the diffracted wave scatfeted from the break point is enhanced, and the interpretation of samll KCC is improved. This application has obtained favorale restdt in the actual work.
