67 Cutting Charges
Curing
Härten; aushärten; maturer
Polymerization of prepolymer or monomer component of mixed propellants
to increase mechanical strength.
Cushion Blasting
Hohlraumsprengen; fir avec chambres d’expansion
A method of blasting in which an air space is left between the explosive
charge and the stemming, or in which the blast hole is purposely
drilled larger than the diameter of the explosive cartridge to be
loaded; W Contour Blasting.
Cut Off
Abschlagen einer Sprengladung; decapitation
Separation of a part of a borehole charge by the blast effect of another
shot in electrical delay firing circuits. Cut off can also occur to the
whole burden of the borehole charge by previous shots; W Permitted
Explosives.
Cutting Charges
Schneidladungen; charge creuse pour découpage
Cutting charges serve to cut through iron plates, cables, bridge
trusses etc. They are constructed on the principle of W Shaped
Charges, but are not rotationally symmetrical; their shape is that of
long channels (grooves).
The cutting depth of these charges depends to a considerable extent
on the thickness and lining material of the angular or semi-circular
groove; in addition, the optimum distance from the target must be
determined in advance.
As in rotationally symmetrical hollow charges, a jet of highly accelerated
gases and metal fragments is produced.
