The subject defines the basic concepts in the field of technical blasting. The main objective is to explain the design of different type of blasting works, the partial aim is direct to compile knowledge on the use of technical blasting for various purposes. It is also referred to the analysis of the damaging effects of blasting focusing on the seismic loading of buildings (methodology according Czech Technical Standard CSN 73 0040).
