Pattern and effect of the high density 3D seismic exploration in coal mining districts

Safe and efficient production of coal mine requires higher and higher precision of 3D seismic exploration. How to further improve the precision of exploration, design ideas, acquisition methods, processing and interpretation of each link are of vital importance. High density three-dimensional seismic exploration in coal mining districts adopts the reception by digital detectors. The observation method is of omni, high density and large offset, so that the information closer to the ideal wave field can be obtained. Broadband processing is adopted to obtain the data body with broadband and high fidelity, which lays a good foundation for interpretation. the high density three-dimensional seismic exploration projects in Huaibei mining area in recent years were taking as an example, from the observation system design optimization, the train of thought and method of processing and interpretation, the project construction process control and other aspects, a new pattern of high density three-dimensional coal mining districts seismic exploration was summed up, which has certain significance for further improvement of the precision of 3D seismic exploration, providing detailed basic geological guarantee data for the design of mining districts and mining in working faces.
