STAND FOR DETERMINING FACTOR CONVERSION RATIO OF BASIC EXPLOSION explosive charge after finding it in the water

摘要

The utility model relates to mining, namely to conduct blasting operations at the enterprises of various industries, and can be used in particular to adjust passports blasting using explosives with reduced sensitivity to detonation as a result of finding them in the water.; Stand proposed to determine the scale factor of the basic indicators of the explosion of the explosive charge after finding it in water, consisting of a mortar-shirts 1 channel 2, wherein the subject has explosive charge 3 to promdetonatorom. Before the mortar on hangers 7 mounted coaxially at a distance of 200-250 mm from its slice channel of the anvil cylinder 6. The lead 9 is arranged between the rear end of the anvil and the rigid support. First blast explosive charge, is in the water and measure the reduction of the lead cylinder is then mounted "dry" charge is the same explosive, lead cylinder is replaced and generate the following firing. As a result of explosion of the two charges, aged at least 24 hours in water, and the two "dry" charge conversion factor is determined by the following formula:; K _n = Δh / Δh ₀; where Δh - lead cylinder compression sustained in the water charge mm;; Δh ₀ - Compression lead cylinder "dry" charge mm. The proposed stand makes it possible to determine the relative effectiveness of the charges after their immersion in water. 1 z.p.f., 1 fig.
