  Extraction of the copper ore deposit in the Legnica-Glogow Copper Basin in
Poland is usually associated with high seismic activity. In order to face this
threats, a number of organizational and technical prevention methods are
utilized, from which blasting works seem to be the most effective. A
significant number of recorded dynamic events may be clearly and directly
explained by the effects of this approach. It is also expected, that the
simultaneous firing of a number of mining faces may provide the amplification
of vibrations in a specific location chosen within the rock mass. For better
recognition of a such process, formation of an elastic wave generated by the
detonation of explosives in a single mining face have been evaluated using the
numerical tools and verified by the field measurements of ground particle
velocity and acceleration parameters, i.e. PPV and PPA parameters. The primary
objective of presented paper was to find the bridge between numerical
simulations of the time-dependent seismic particle velocity values induced by
blasting and in situ measurements using seismic three component geophones
