This paper summarises the results of underground seismic measurements conducted between 1993 and 2013, and seeks to identify some empirical dependencies by determining the decay of particle velocity according to the scaled distance from the foci of the rockbursts. The scaling distance r* is defined for rockbursts by the formula r* = d/√E (m.J−1/2), while for explosions the formula r* = d/ 3√Q (m.kg−1/3) is usually used. The seismic energy, local magnitude and focus coordinates of the rockbursts, as well as positions where damage to workings occurred, were employed as additional inputs.
