摘　　要：开采前了解煤厚的变化情况既可提高安全性又能降低开采成本。三维地震资料虽然横向连续性好,但是垂向分辨率还达不到解决煤厚的要求;测井资料虽然垂向分辨率高但因为钻孔数目的限制,煤层的横向连续性又得不到保证。利用波阻抗反演对煤层厚度进行解释,既结合了地震资料与测井资料的优点又互相弥补了不足。Understanding of changes in coal thickness before the exploitation can improve security while lowering production costs. Although the horizontal continuity of 3D seismic data is excellent,the vertical resolution is less than the requirements to solve coal thickness prediction;Although the vertical resolution of logging data is good, it is .hard to ensure the horizontal continuity of coal seam because of the number of drilling is limited. It combines the advantages of seismic data and logging data to explain the thickness of coal seam by wave impedance inversion.
