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.
