Abstract：The geologic conditions of surface and underground of 3-D,3-C seismic prospecting working area in Qianjiaying coal miner are complex and interference wave is serious,increasing the difficulty for data processing.The processing expounded by the paper used the self-made modules,including CCP gathers sorting,velocity analysis and NMO of converted wave(C-wave) and static corrections of converted wave.During the total C-wave data processing,we pay more attention to hi-fi processing of amplitude,the noise-removed tools that can destroyed the amplitude feature are not applied;the non-symmetric ray path is considered in static correction at receiver points;the density of velocity spectrum adopted by NMO is 1000m×1000m,the spatial velocity field is smoothed;the full wave equation is used for migration and optimum coupled velocity of P-wave and converted S-wave migrated velocity is used for migrated velocity.The process- ing results showed the quality of sections can meet the demand of exploration.
