FIELD: mining.
SUBSTANCE: the invention group relates to method and device for demolitions work with low blasting charge, and a drilling machine for rocks used with it. A well is drilled in the mined material using a drill from the drilling machine for rocks, then one or several shells with propelling charge are fed through the drill to the bore-hole bottom. The drilling machine contains a shell feeder which is separated from the drill, the feeder allows to feed shells to the longitudinal channel of the drill.
EFFECT: uninterruptible demolitions work while using standard drilling machine for rocks.
