FROM THE EXPERIENCE OF OPERATION OF MINING ENTERPRIES AND COMPANIES
ArticleName Researching of influence of parameters of drilling and blasting operations on reset coefficient during explosive displacement of mine ores with different durability
ArticleAuthor Bibik I. P., Zairov Sh. Sh., Ivanovskiy D. S.
Abstract
The results of pilot-industrial explosions on reset of overburden with different durability in exhausted areas of quarry of Dzheroy-Sardarinskiy phosphate deposit have been presented. Empirical formula for determination and optimization of reset coefficient in relation to specific consumption of explosive materials, angle of inclination of down hole, width of split, high of ledge and power of strong proplastics has been proposed on the base of this results.
