  • 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.
