Abstract:

The mechanism of blasting seism is complicated with numerous influencing factors. In order to find out the controlling factors of blasting seismic effect, the grey correlation theory of grey system is introduced. By conducting case analysis, the pecking order influencing blasting seismic effect is obtained; and it is pointed out that the super-deep drilling , pore network parameters are the controlling factors of the seismic effect. The most effective way for reducing the blasting seismic effect is to optimize these blasting parameters. The calculation of grey correlation analysis method is characterized by simplicity, reliable results and convenience for use; so it is of favorable value to the blasting engineering.

Key words: blasting seismic effect, grey correlation analysis, master factor, shock absorption
