三维地震勘探数据体反演分析方法预测小断层研究

Prediction of Small Faults by Inversion Analysis of 3D Seismic Exploration Data Volume

小青煤矿在东一、北二等采区采用三维地震勘探技术补勘,获取多条落差5 m以下小断层。根据采区采掘实见小断层资料,使用煤矿三维地震数据动态解释系统,对三维地震勘探数据体小断层数据进行反演分析,预测小断层发育情况对采掘工作面影响,以指导回采工作面的设计、采掘工作。

In Xiaoqing Coal Mine,three-dimensional seismic exploration technology was used in the east first and north second-class mining areas to obtain several small faults with a drop of less than 5 m.According to the data of small faults in mining area,the 3D seismic data dynamic interpretation system of coal mine is used to carry out inversion analysis on the small fault data of 3D seismic exploration data volume,so as to predict the influence of small fault development on mining face,so as to guide the design and excavation work of mining face.
