COMBINATION CHARGING TAMPING

摘要

FIELD: drilling and blasting operations, applicable in various branches using blasting operations in rock masses. ^ SUBSTANCE: the combination charging tamping including a monolithic stopper of hardening materials is made of the upper and lower parts, the upper part represents a monolithic stopper of hardening materials, and the lower part-a charging of inert free-flowing materials over an air gap of foamed polystyrene. ^ EFFECT: enhanced efficiency of blast crushing of rocks due to a complete choking of the detonation products in the charging space up to crushing of the surrounding rock by a shortened combination tamping with an air gap over the charge. ^ 1 dwg
