The proper application of geophysical programs makes it a valuable tool in the mining industry for locating underground features that could interfere with mining activities. Used in concert with traditional exploration procedures (i.e., drilling or excavating), these geophysical programs can materially expand the exploration horizon of the user and improve the accuracy in locating those features that may affect mining activities. This presentation reports on a selected number of experiences involving the use of surface-applied geophysics as well as in-seam techniques for coal mining related purposes.
