【摘要】 岩溶陷落柱在华北煤田中广泛分布,严重影响矿井的设计和生产。笔者通过建立正演模型,利用模型数据的偏移结果进行地震属性的提取与分析。对部分地震属性的分析和对比表明,溶洞的横向尺度大小在振幅类、频率类、相位类属性都有较好的反应,纵向尺度可由谱分解属性定量。更多还原

【Abstract】 Karst collapse is widespread in the coal field of northern China,which takes a serious influence on the designing and production of mine well.On the basis of establishing the forward model,this article made use of migrate result of model data to extract and analyze the seismic attribute.Some analysis and contrast indicate that the lateral scale of karst cave reacts well in the attributes of amplitude class,frequency class,and phase class.The vertical scale can be quantitated by the spectral decomposition attribute.更多还原
