摘要
Abstract
Conventional single blocking material is used in blast hole in mine blasting,which could result in punching phenomenon.Variable control method and contrast analysis method were used to qualitatively analyze the correlation of stress and time in blast holes.In blasting test,blast holes were blocked by six scenarios,and it was obtained that mixed material using in blast hole has the highest anti-cut strength,the longest action time for energy of explosives in holes,and the strongest work capacity.Mixed material used as blocking materials could effectively reduce the occurrence of punching,increase utilization and reduce hole upper block.关键词
