Abstract
In order to improve the quality and efficiency of blasting operations,enhance the utilization rate of explosives,and ensure the benefits of open-pit mining,the article analyzes the commonly used types,principles,applications and optimization schemes of air interval charging technology in open-pit coal mining,and summarizes the advantages and problems of air interval charging technology.The research results indicate that using 1.20m PVC pipes for air interval charging in open-pit coal mines can to some extent limit the propagation of blasting energy,reduce unnecessary energy loss,and ensure good blasting effect,avoiding the production of too many large rocks.关键词
