Abstract
A blast hole includes explosive substance in which a string of initiators on threads of detonating fuse is placed, and distance between initiators is determined by the ratio. Over the charge of explosive substance in the well a plug with locking charge in it is placed. The locking charge is arranged with capability of initiation after operation of well charge of explosive substance at boundary with plug. Initiators in the string and the locking charge are made of emulsion explosive substance as separate cartridges and are connected to one main of two threads of detonating fuse. The threads of detonating fuse between the cartridges are placed in multi-layer tube made of polymer material, with number of layers not more than three, this is safety barrier between detonating fuse and the charge of explosive substance in the well. Blast hole is arranged with possibility of feeding initial pulse by means of well capsules – detonators of non-electric initiating system to the lower initiators in the string.
