Garland contour blasting charges (ZKVG) TU 84-1143-87

"A load-carrying cord is passed through the center of the charge, which allows fixing the garland at the wellhead, increasing it along its length, and also protecting the shell of the charge from excessive axial deformation and destruction under the influence of gravity of the ZKVG. in boreholes with a diameter of 105-250 mm, a depth of up to 30 m, vertical or inclined. The field of application is blasting on the earth's surface. The main characteristics of the charge: the mass of the link is 1.37 kg, the mass of the charge is 23.43-25.89 kg, the mass is Explosive per 1 running meter, kg -2.60 ± 0.130, explosive density, g / cm³. Technical characteristics: – explosive density: 0.95 – 1.10 g / cm³; – gas volume: 895 l / kg; – oxygen balance: – 0.53%; – detonation speed: 3.6 – 4.8 km / s. Guaranteed shelf life – 18 months. "
