Application of Liquid Oxygen Cracking Blasting Technology in an Open-pit Mine
Liquefied oxygen cracking rock mass is a new blasting technology developed today.The field test method is used to compare and analyze the blasting vibration test data and the cracking blasting ef-fect,and the actual effect of this technology in open-pit mines is studied.The results show that there is no harmful gas generated during the implementation of liquid oxygen blasting technology,and the vibration damage to the surrounding permanent side is small.There is no obvious flying rock in the liquid oxygen blast-ing,which minimizes the hard damage to the surrounding.This technology is suitable for blasting in special environment with high requirements for blasting disturbance control,and has popularization significance.
