THE DETECTION OF SMALL FAULTS USING FUZZY PROBABILITY METHOD AND ITS APPLICATION IN LONGDONG AREA

The high resolution 3-D seismic exploration has been became the main tool for the productive supplementary exploration of coal mining area.Its basic task is the interpretation and ascertains of the faults with the throw ≥5 m through the man machine intersection.This paper applies the fuzzy probability to detect the small faults.Through the research and detection in the 3-D seismic exploration area of Xifu sector in Longdong mine,the exploration accuracy of the throw of small fault is increased to about 3m.Based on the verification of the mine party,the detected faults have the higher accuracy and precision,with the high efficiency.
