摘　　要：针对淮南煤田的地质情况——煤系地层的分布和岩性特征,研究了煤系地层地震地质模型的制作方法与弹性测试,对地震物理模型进行数据采集与处理,得出地震物理模型的地震响应特征。研究结果表明:煤田地震物理模型技术的关键是低速煤层和裂隙带的模拟制作;煤系地层地震物理模型可以指导煤田地震勘探、认识煤田地震波场特征。Based on geological conditions of Huainan coalfield,including distribution of coal strata and lithologic features,production and testing of seismic geology model of coal measure strata in Huainan were completed.Seismic data acquisition and processing provided clearly the seismic reflection characteristics of the physical model.The results show that the simulation production of low speed coal seam and fractured zone are key of the seismic physical modeling techniques,at the same time,seismic physical model guides coal seismic exploration,helps to understand characteristics of seismic wave field.
