煤层巷道间的弹性波CT技术

The elastic wave CT technology in seam roadways

弹性波CT是根据弹性波在地层中的传播规律,将观测到的资料表示为某些地层参数沿特定路线的积分,并反演这些参数的过程。主要利用地震波(直达波、反射波、折射波、面波等)的到时来重建速度图像,因此也被称为走时CT,是目前地震CT中应用较多的一类。

CT elastic wave is on the basis of the formation of elastic wave propagation, will be observing the information for certain formation parameters along specific routes integration, and these parameters inversion process. Major seismic wave （direct wave, the wave reflection, refraction wave, surface wave, etc.） when the speed of image reconstruction, it is also known as the walking CT, CT is the seismic application of a larger category.
