| With the increasing difficulty of coal mining in China,the difficulty of geological exploration is also increasing.Mechanized coal mining requires higher and higher accuracy of geological exploration.At the same time,the accuracy of seismic exploration and geological data interpretation is also greatly improved.Ordinary 3D seismic exploration technology has been difficult to meet the needs of complex geological exploration.Therefore,it is urgent to improve the accuracy of 3D seismic exploration.In order to further find out the coal seam scour and magmatic rock distribution in Yangying coal mine,the pre stack time processing technology and CMP were used Coherent inversion technology,refraction static correction technology,automatic residual static correction technology and other new technologies process high-precision 3D seismic exploration data and lithology inversion,so as to improve the signal-to-noise ratio,resolution and fidelity of the time section of the earthquake,and make the display of the fault clearer,more reliable and more accurate.At the same time,the increase of resolution also makes T3 wave correspond to the occurrence of 3 coal seam(thickness change,influence of magmatic rock,etc.),which lays a good foundation for the next treatment of coal seam thickness and magmatic rock erosion.This paper is mainly to solve the practical problems of Yangying coal mine by using scientific theory and technology.By improving the signal-to-noise ratio,resolution and fidelity of the time section of the earthquake,the display of the fault is clearer,more reliable and more accurate.Therefore,the accuracy of 3D seismic exploration can be improved to discuss the thickness of coal seam and the erosion of magmatic rock. |
