Technology of coal field 3D high-resolution exploration and its application

Through scientific researches of applying computer technology to coal field 3D seismic exploration, the results are given in this paper with examples of production. A set of high-resolution 3D seismic data processing flowchart for coal field, with features of 350Hz frequency width and dominant frequency near 200Hz, has been developed for many years. It provides reliable information for determining fault with throw of 5m. 52 faults have been determined within an exploration area of 2.9 km(2), which provides detailed data for layout of the tunnel and produces enormous economic benefits.
