Seismicity in mines, in general, depends on depth, production rate, mining geometry and geological discontinuities such as dykes, faults etc. and on ambient tectonic stress field. One or combination of the above factors may contribute significantly to mining seismcity in any specific case (Gibowicz and Kijko, 1994; Mendecki, 1997; Holub, 1997; Holub et. al., 1995)). It is often observed that most of the damaging events, commonly known as rockbursts, are induced at the geological discontinuity in the mining area, Figure 5.1. Most of the seismic events less than magnitude zero in the Richter scale are induced following production blasting.
