Abstract
The paper considers the issue of seismic protection of the environment and protected objects during drilling and blasting method of tunneling. It is shown that the creation of a cut-off slot reduces the amplitude values of seismic blast waves at least three times. This experimental fact made it possible to use the cut-off slit for tunneling the gallery of the Krasno-Polyansky tunnel using blasting.
