Abstract: The effect of deep hole pressure release blasting on impact ground pressure treatment is accepted by miner.Through analysis of blasting rock-broken theory, the basic principle of blasting destressing was proved, applications of deep hole blasting destressing on impact ground pressure prevention was researched. The main parameters of deep hole blasting like borehole diameter, borehole spacing, hole depth, sealed borehole length and so on are confirmed and optimized.

Key words:  Deep hole blasting, Pressure relief, Impact ground pressure
