Pattern recognition principle of 3-D seismic exploration and its applying effect on mine engineering fissure zone

本文从时间域、频率域、三维空间域介绍了矿山工程裂隙破碎带主要的地震运动学、动力学属性参数,包括相对振幅、波峰相位时间、相似系数、主频带能量、三维空间时间梯度和相干系数等,提出了矿山工程裂隙破碎带三维地震属性的去噪平滑、归一化、相关分析、特征变换的处理方法以及裂隙破碎带的模式识别原理与方法,并用实例说明了该方法的应用效果。结果表明:模式识别法对于解释矿山工程的裂隙破碎带是有效的,并具有广阔的应用前景。

We discussed the main characteristic parameters of seismic kinesiology and dynamics of mine engineering fracture zone,including relative amplitude,phase time of wave crest,similarity factor,principal frequency band energy,3\|D space time gradient and coherent coefficient et al.,and puts forward the processing method of 3\|D seismic characteristic parameters about denoise\|smoothing,generalization,correlation analysis,characteristic transformation; and presents the method of pattern recognition of mine engineering fracture zone.Applying effect of the method is demonstrated with an actual example.
