ABSTRACT

Efficient protection and construction of engineering and other structures in seismically
active areas is a series of contradictions, where an optimum solution must be found,
which does not comprise a compromise at the expense of safety and security of the
people, and which minimizes damage of property.

Along with the increase of the needs for energy, the need for open pit mining production
increases, which is related to the mass blasting with increasing quantities of explosive,
and nearing to the population centers. The seismic effects of blasting become more
common, and also the seismic danger for the structures by mass blasting. The velocity
of soil vibration during blasting depends on the quantity of explosive charge and
distance of the blasting site and the affected structure. It is represented by equations
containing a series of parameters including most of the relevant influences. These
expressions are not uniform, because they depend on multiple influences, so it is most
frequently necessary to experimentally determine them for each individual case.
Therefore, seismic safety of structures during blasting is provided by a variety of factors
with variable protection efficiency.

Keywords: blasting, seismic, mining pits, stability, structure.
