The combined driving of the well charge includes a hydraulic breaking in the well, a vessel with an explosive substance, a charge for initiating blasting, driving, a chain for initiating blasting. The firing initiation circuit passes through the driving part above the explosive vessel and is connected to the firing initiation charge. Note here that hydraulic seal composed of chemisorbent suspension is arranged between well wall and vessel with explosive. Reservoir is made of waterproofing material and has diameter smaller than diameter of well and is arranged along its axis. Blasting initiation charge is arranged in vessel with explosive.
utility model relates to mining industry, in particular, to means of crushing of mountain massif and can be used for normalization of atmospheric air condition and dust localization at open method of development of mineral deposits with application of explosive breaking of rocks, including creation of liquid curtains over working platform.
