摘　　要：依托鄂尔多斯盆地西缘桌子山矿区某一煤矿区三维地震工程,从地震地质条件、技术难点及其应对措施、数据采集、数据处理及成果方面,研究了该矿区三维地震采空区探测技术的应用效果。野外数据采集的单炮记录煤层反射波同相轴清楚,叠加剖面煤层反射波同相轴信噪比高,采空区特征明显。最后根据处理数据体,对研究区内采空区位置及边界做出了解释,经钻孔验证,采空区位置正确。Base on the seismic geology, data acquiring, data processing and the result, researched a 3D seismic survey in coal mine in Zhuozishan mine field of Ordos basin. The events of single shot records display obviously. The reflected waves of the coal seam in stacked sections also have a high STN, and the worked-out sections characters are obviously. Finally, explained the boundary of the worked-out sections according the processed data, just as the discovered by producing.
