Abstract

The energy generated by the explosion of some quantity of explosives, have broken and breaking rocks, cracks form and various deformations in the surrounding rocks. Around of blasting place and outlying areas the generate detonated wave, causing elastic deformation, concentrically arranged around the mining area.
These (seismic) waves passing through a rocky massif cause oscillations of the particles from the ground and surrounding buildings. Blasted series performed on surface and underground mines, cause different effects on the environment in terms of intensity of the shocks, air shocks and pieces of blasted rock mass.
These negative effects can cause harmful effects on humans and buildings. For protection from the harmful effects introduced standards, criteria and restrictions on the intensity of these effects, especially the allowable intensity of tremors on the ground to some distance from the blasting series.
Therefore there is a need for control, measurement and regulation (as possible) the oscillations of the ground and seismic shocks caused by these oscillations occurred as the effect of sapping the blast.
In order to evaluate and control the effects of seismic blasting, it is necessary to determine the soil oscillation law in direction and ground distance to the appropriate place or object that are to be protected.
Keywords: blasting, explosion, rock decomposition, oscilations, seismic effects, safety distance.
