FIELD: mining.
SUBSTANCE: there is disclosed facility for explosive method of stripping operations at open development of bedded deposits of minerals; mentioned facility consists of initiator made in form of arc with cross section radius equal to maximal diameter of charge; also length of arc is equal to 0.9 of value of smaller diameter of charge; notably, braid is made with rigid guides in form of arc in cross section.
EFFECT: facilitating increased volume of transferred rock with directed explosion into worked out space due to directed initiation of charges along arc in direction of rock motion.
