Abstract
In order to research the influencing factors of the loosening blasting effect of deep hole steps in open-pit mines,based on engineering blasting theory,combined with knowledge of rock dynamics,mining rock blasting mechanism,geostatistics,etc.,the article compares the practical experience and blasting safety management measures of deep hole blasting engineering at home and abroad,analyzes the factors such as rock explosiveness,explosion characteristics,blasting parameters and technology,and proposes the optimization measures for the parameters of deep hole step loosening blasting in open-pit mines,which realize safe and efficient blasting in open-pit mines and achieve the goal of the cost reduction and efficiency improvement.关键词
