Abstract：Analyzed the rock breakage process in borehole blasting,put forward the"dynamic and static press" breakage principle of rock borehole blasting.Used AUTODYN software make borehole blasting numerical simula-tion,educed the borehole blasting of rock breakage process and analyzed the borehole non-coupling charge blasting law,achieved a complere set of technology by combination of theoretical analysis,numerical simnlation and to the mining roof weaken site implementation.At last,verified the condusion of study by drilling observe on-site blasting cracks and monitor the pressure laws.
