Anotace:
The paper is focused on the measurement of adverse effects caused by blasting works in tunnels on the environment. The disintegration
of the rock massif during tunnel construction is performed in most cases by explosions due to the release of the explosion energy, which is
transformed into the energy of the seismic waves and causes disruption of the massif balance. Blasting works generate noise and seismic
waves with different maximum vibration velocities and a wide range of frequencies. The intensity of the seismic waves is proportional to the
massif of the explosives used. If the vibration has sufficient energy, the surrounding buildings may be damaged or destroyed. Assessing the
negative effects of blasting and quantifying seismic security is currently a very challenging issue. However, based on periodic measurements,
prediction of these effects is possible. The paper presents the results of monitoring of blasting works in tunnels in the Slovak Republic. The
evaluation of noise and seismic effects of blasting works verified that in tunnels is a methodological basis for noise and seismic effects of
blasting works not only on surrounding buildings but also on the surrounding environment.
