地震相分析技术在煤田地震勘探中的应用

地震相分析技术日渐成为煤田岩性地震勘探的一门新技术。阐述了基于波形分类的地震相分析方法，通过人工神经网络地震相检测技术对不同的波形进行分类，达到区分不同目标体的目的。以圈定火成岩发育范围、预测煤层冲刷变薄带和识别断层、陷落柱等地质异常体为例，讨论了地震相分析技术在煤田岩性地震勘探方面的效果。 

Application of seismic facies analysis technology in coal seismic exploration

Seismic facies analysis technique has become a new technology of coal lithology seismic exploration. This paper expounded the seismic facies analysis method based on waveform classification, classified different waveform through artificial neural network detection technology to classify different waveform to achieve the purpose of distinguishing different targets. Respectively using the methods to delineate the scope of igneous rocks, to predict washing-thinned belt of coal seam and to identify fault, collapsed column and other geological anomalies as examples, the effectiveness of the seismic facies analysis technology in the field of seismic exploration for the lithology of coal field was discussed.
