Daisy chain explosive charges (DCED) TU 84-1143-87

They represent a polyethylene hose with a diameter of 60 mm, filled with ammonite No. 6ZhV GOST 21984-76, with staples of aluminium wire along the length of the hose every 500 mm (link length). A load-bearing cord is passed through the centre of the charge, which makes it possible to fix the garland at the wellhead, to increase its length, as well as to protect the charge shell from excessive axial deformation and destruction under the action of the gravity of ZKVG. The charges are designed for scarping of ledges, sides of quarries and mine workings by contour blasting in boreholes with diameter 105-250 mm, depth up to 30 m of vertical or inclined location. The field of application - blasting on the earth surface.
