R. Meyer J. Köhler A. Homburg Explosives

Channel Effect
Channel Effect
Kanaleffekt
Interruption in the detonation of an explosive column because of the
compaction of the cartridges which have not yet exploded due to the
gas shock wave front in the borehole. This happens very often if the
borehole cross-section is large as compared to that of the cartridges.
Chlorate Explosives
Chloratsprengstoffe; explosifs chloratés
Explosive mixtures of alkali metal chlorates with carbon-rich organic
compounds such as wood dust, petroleum, oils, fats and nitro derivatives
of benzene and toluene; they may also contain nitrate esters.
Their strength is lower than that of ammonium nitrate explosives in
powder form. Chlorate explosives must not be stored together with
ammonium nitrate explosives, since ammonium chlorate, which is
formed when these two substances are brought into contact, decomposes
and explodes.
“Miedziankit” is the name of absorbent potassium chlorate particles,
which are impregnated with a liquid fuel just before use, and then
acquire explosive properties. Following the development of W ANFO,
this explosive is no longer of interest.
Cigarette-Burning
Stirnabbrand; combustion en cigarette
W Face Burning
Circuit Tester (Ohmmeter)
Zündkreisprüfer; éprouveur; blasting galvanometer
Instrument for electrical testing of misconnected circuits. The current
intensity used in the testing must be well below the W No Fire condition
of the electric detonator; the circuit tester is accordingly equipped
with resistances at both poles. Only officially approved testers should
be employed. The testers are of two kinds: conduction testers which
show, by means of a visual indicator, whether or not current is flowing
in the circuit, and ohmmeters which measure the resistance of the
priming circuit.
