Methodology of designing blasting works in open pit mining in terms of their impact on construction objects

a wide range of possibilities in designing multi-row blasting
patterns and, at the same time, contributes positively to the
minimization of the impact of blasting works on building
infrastructure in the vicinity of mines. Selection of the appropriate
millisecond delay should be based primarily on seismograms of
vibrations induced during the firing of single explosive charges and
analysis of the frequency structure of these vibrations. Using this
type of data, the article presents a procedure for optimizing
millisecond delays with the use of a computer programme dedicated
to modern, electronic initiating systems that are currently applied
towards obtaining a favourable vibration structure in terms of the
assessment of the impact on buildings in accordance with the
standard regulations applicable in Poland.
