| 摘 要： | 1 Introduction3D seismic prospecting plays important roles incoal mining because of it necessity to geologic sur-vey. Owing to using many new theories and tech-nologies, the resolution of 3D coal seismic prospect-ing is increased continuously, the geological structurecan be detected more and more accurate. ButRayleigh's criterion shows that the resolution thresh-old of the seismic reflection wave is λ /4 (λ iswave length of seismic wave ).The resolution of logging data is very high, andit c…

| Abstract: | Seismic inversion is one of the most important methods for lithological prospecting. Seismic data with low resolution is converted into impedance data of high resolution which can reflect the geological structure by inversion The inversion technique of 3D seismic data is discussed from both methodological and theoretical aspects, and the inversion test is also carried out using actual logging data. The result is identical with the measured data obtained from roadway of coal mine. The field tests and research results indicate that this method can provide more accurate data for identifying thin coal seam and minor faults. |
