模糊概率法检测小断层的研究及在龙东区的应用

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

高分辨三维地震勘探已经成为煤矿采区生产补充勘探的主要手段，它的基本任务是通过人机联作解释查明落差≥５ ｍ 的断层。本文采用模糊概率法检测小断层，通过对龙东矿西辅块段三维地震勘探区的研究与检测，可以将小断层落差的勘探精度提高到３ ｍ 左右。检测出的小断层经矿方验证，精度与准确度较高，效果明显。

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.
