In order to solve the problems of complex surface conditions, poor excitation and reception conditions and low signal-to-noise ratio in mountainous areas, and further improve the accuracy of three-dimensional seismic data, taking the structural exploration of Shouyang Jingfu Coal Mine in Qinshui Coalfield as an example, this paper summarized a high-precision three-dimensional seismic data acquisition and processing scheme. The acquisition mainly included excitation parameter test, observation system interaction optimization and other methods. The processing mainly included surface consistency amplitude correction, multi-level comprehensive static correction, multi-dimensional comprehensive denoising and other technologies. Through the comprehensive application of various technologies, the high-precision three-dimensional seismic data volume was finally obtained while meeting the exploration requirements. The practical results showed that the scheme could adapt to relatively complex surface conditions and provide a solid data foundation for seismic data interpretation.
