Abstract

With „seismic magnitude of lithomedia” is defined the maximal possible (source) amplitude of a monolith from a lithomedium. The generation of seismic effect due to blastic explosions follows the process of „crack-like deformation of the blasted monolith”, with the following regularities: each (monolith of) lithomedia has a „characteristic boundary particule velocity of seismic vibration”, below which there is no plastic deformation and above which there is no elastic transfer of stress waves. The boundary particule velocity of seismic vibration is the strength characteristic of lithomedium. It is not depend from the power of the generator of seismic effect (earthquake, explosition, blows,...), and can be defined in dependance to the lithomedia. Analogously with expression of the destructiveness of hard rocks with blasting, it is also suitable to express the seismic magnitude of a lithomedium in correlation with the seismoacoustic impendance of the blasted lithomedium. With establishment of a „correlative relationship” between seismic magnitudes of lithomedia and acoustic impedances of the sames lithomedia on upgrade the defining and operating with distribution of seismic effect due to blasting.
