Seismo-Acoustic Determination of the Boundaries of Zones in Coal Seams Subject to Rock Bursts
In the various studies of rock bursts, it has been shown that the appearance of dynamic phenomena in worked coal seams can be characterized into zones [1, 2, 3]. Rock bursts have been found in faulted zones more than once. However, the statistical data on actual bursts are not adequate to prove that the danger areas in all seams are zoned. The zoning question remains debatable, and practical observations are needed to settle it.
