A high resolution 3D-seismic technique for distinguishing geological structure in the complex coalfield

摘要

Processing the high resolution seismic data and comparison with the data obtained from mining workings allows definition of the seam variations, the small-scale geologic structure and the texture of coal. For the described examples, nine faults with >=3-m drop height, three faults with >=1-m drop height and four structural loose zones located in about 680-m depth are found in 1.2 kilometers square area of the reserch district. It provides a useful large-scale experimental meausre for the seismic exploration.
