Abstract | For the first time the quantitative classification of blasting operations as sources of blasting vibrations is constructed. According to the classification, all sources are divided into the sources of increased, normal and reduced action. The classification is based on the rectilinear dependences of the PPV attenuation factor on the logarithm of the seismicity coefficient, which are included in Sadovsky’s formula to predict the peak particle velocity under the seismic action of explosions. The classification is based on the statistical analysis of 76 seismicity coefficient—PPV attenuation factor couples reflective of the wide geography of blasting operations carried out in solid minerals mining and in civil engineering. The reliability of the statistical analysis result is proved using the Fisher criterion and Student statistics. The classification boundaries of seismic sources are verified. The sources of increased seismic activity are compared by the conditions of blasting in watered and in very strong rocks, the use of largediameter blast holes, the choice of explosive mass for simultaneous blasting and the influence of the initiation method on the seismic effect produced. The sources of normal and reduced seismic activity were compared by the conditions of blasting in underground mines, at quarries of building materials with ground surface recording, blasting in civil construction and with preliminary borehole slotting. The classification allows the quantitative comparison of blasting operations by the level of seismic action in the intervals of 6–2700 and 0.6–2.8 by the seismicity coefficient and PPV attenuation factor, respectively, for PPV in cm/s. The classification is representative of the current technology of blasting in the world practice. |
