摘要
以东庞矿2903工作面突水陷落柱为例,利用三维地震的纵横剖面、联井剖面、等时切片与沿层切片对陷落柱进行了对比解释,并对偏移速度90%、95%和103%的3个不同地震数据体上陷落柱边界的控制效果进行了分析。结果表明:偏移速度95%的地震处理效果较好,地震沿层属性切片技术对陷落柱的解释精度最高。
Based on the analysis of subsidence column prospecting in Dongpang coal mine,the effect is discussed for subsidence column interpretation in 3D seismic vertical section,hole-linked section,horizon time slice and coal-layer attribute slice.With the seismic migration velocity of 90%,95% and 103% to stack velocity,three different 3D data cube have been interpreted and their effect is compared in this paper.The results show that the 95% migration velocity is better and coal-layer attribute slice technology is the best in subsidence column prospecting.
