Techniques for detecting faults ahead of coal mining operations using channel waves have been tested in a Western US coal mine in a panel of coal where a fault with throw greater than the seam thickness (10 ft) was known to exist. Attempts to image the fault using the techniques that have been used for several years in thinner seams in the UK failed due to noise from multi-model propagation in this seam. An image of the fault was obtained by using an inversion technique referred to as virtual reflector imaging (VRI) the inversion yields a simultaneous solution for group velocity, phase velocity, reflector intercept, and reflector slope.
