Improving Spore Clamping with Pair of Hydroampules in Blast Mining

Abstract

At present, the share of coal and oil in the world energy balance is almost equal. The article envisages the use of two pairs of hydraulic ampoules to block the boreholes in the blasting of layered deposits, which will increase the blasting efficiency by directing the bulk of the blast energy to the decomposition of the ore mass. In addition, information is provided on the types of pipes used for sealing, as well as the effect of placing the plugged hole using two hydraulic ampoules.
