摘要(Abstract)：

查明煤层瓦斯富集区域,对可能的瓦斯突出点进行预报,是当前煤矿生产中亟待解决的重要课题。利用地震P波对裂缝性地层所表现出的方位各向异性特征,根据地震属性随方位角变化可以预测裂隙发育方向和密度的基本原理,应用多种地震P波方位属性预测裂隙发育带。通过对淮南张集煤矿西三采区三维地震P波资料的处理,获得6个方位地震数据体,从中提取多种与煤层和围岩裂隙相关的地震属性,并计算出裂隙的发育方向和密度,为确定瓦斯富集带的分布提供了一种新的途径。
It is an important problem to be urgently settled that the coalbed methane enriched area must be detected and the possible gas outburst position should be predicted during the coal mine production.Based on the azimuth anisotropy of seismic P-waves to fractured strata and the prediction principle of the fracture orientation and density utilizing seismic attribute variation with azimuth,fracture zones are detected using seismic P-wave azimuth attributes.Affter 3D seismic P-wave data in West 3 mining area,Zhangji coalmine,Huainan,are processed,6 azimuth data cubes are obtained from which several attributes related with coal and roof/bottom fracture are extracted,and then,fracture density and orientation are measured.This method is a new tool for locating the distribution of coalbed methane enriched area.
