| 摘 要： | 为了探测工作面内煤层的构造发育情况，利用槽波波速CT成像技术对工作面内的煤层进行CT成像。首先根据每条槽波射线的波速情况，反演出工作面内煤层的物性参数，再通过改进代数重建算法(ART)对工作面中的煤层进行槽波波速CT成像。应用结果表明，工作面内地质构造预测结果与实际情况吻合较好。

| Abstract: | In order to detect the structural development of the coal seam in the working face,the in-seam wave velocity tomograpgy technology was used for CT imaging of the coal seam in the working face.First,the physical parameters of the coal seam in the working face were inverted according to the velocity of each in-seam wave ray,and then the CT imaging of the in-seam wave velocity of the coal seam in the working face was performed by the improved Algebraic Reconstruction Technique (ART).The application showed that the predicted results of the geologic structutrs in the working face agreed well with the actual situation. |
