Abstract:This paper systematically summarizes the development of Three-dimensional seismic exploration technology in Ningdong mining area to provide technical support for the development and utilization of coal resources in the mining area. Starting from the three aspects of 3D seismic acquisition, processing and interpretation, the development history and latest progress of each technical link are described in detail. In acquisition, the wide-azimuth 5m×5m small surface element size and high-coverage number of times methods are adopted; in processing, high-precision surface static correction, pre-stack noise suppression, amplitude compensation, inverse folding accumulation, pre-stack time offset and other technologies are applied; in interpretation, it develops from the traditional interpretation to the multi-attribute interpretation, artificial intelligence interpretation and other new technologies. After nearly 20 years of development, however, the application of 3D seismic technology in Ningdong mining area still needs to continue to improve in the optimization of acquisition parameters, high-precision processing, and intelligent interpretation. The application of 3D seismic technology in Ningdong mining area has made significant progress, improving the accuracy of identifying small faults in the coalfield, optimizing the acquisition parameters, and improving the processing effect and interpretation accuracy. The continuous progress of 3D seismic technology provides powerful technical support for the precise and transparent development of coal resources in the mining area, which is of great significance to guarantee the safe and efficient production of coal in the mining area. The optimization of acquisition parameters, high-precision processing and intelligent interpretation are proposed as the key directions for the future development of 3D seismic technology.
