Abstract The pre-stack time migration technology is one of the effective means for imaging of complex structure.It can be adapted to the condition of relatively rapid longitudinal and transverse variation and is suitable for migration imaging with large dip angles.With examples,the authors discuss the problems which deserve attention in using the pre-stack time migration technology to conduct coalfield seismic data processing in the structurally-complex area.The results demonstrate that this technology can effectively improve imaging effect of coal seams in structurally-complicated areas and raise coalfield seismic data signal-to-noise ratio and resolution.
