摘　　要：煤层在地震勘探目标层中属于薄层,对其厚度预测具有一定的难度。通过对煤层厚度及地震属性进行分析,得出煤层厚度与反射波振幅存在一定关系,找出采用地震反射波振幅对煤层厚度进行预测的方法。结合工作区的地震资料和已知钻孔对区内煤层厚度进行了定量预测,实践证明,其具有一定的可行性。Coal seam is thin in seismic exploration target layers, the prediction of its thickness is difficult in some degree. Through analy- sing on the coal seam＇s seismic attributes,it was proposed that there is proportional relationship between the amplitude value and seam thickness. A method was found to predict the thickness of coal seam by using the amplitude of seismic reflection wave. With the actual seismic data of the work place and the known drillholes,quantitative prediction about the coal seam thichness was carried out in same area, which was proved to be feasible in practice.
