Description
Technical field
The present invention relates to a kind of viscous explosives, and in particular to a kind of suitable for the viscous without single chmical compound explosive of underground mine explosion
Property explosive and preparation method thereof, belongs to civil blast explosive and its manufacturing technology field.
Background technique
Underground mine blasting explosive is mainly powdery ammonium ladder detonator in the prior art, and many underground mines are all using sky
Pressure charging machine is blown into powder type explosive into blasthole, when to apical pore powder charge, since this powder type explosive causes to return dose up to
10%-20%, to keep the waste of explosive extremely serious, while live medicine dirt is flown upward, and seriously pollutes working environment, worker it is deep by
It does harm to.For a long time, no matter shallow bore hole or deep hole blasting are manual chargings, large labor intensity, and blasthole is not fully utilized again
In some underground mines, some adds a certain amount of diesel oil in powder type explosive and is puddled, and is done over again with reducing it
Dose, but scene is needed to puddle, labor intensity is increased, while adding diesel oil it is also possible to influencing the service performance of explosive, in turn
Explosive applications effect is influenced, blasting cost is increased.In some mirabilite ore underground blastings, mostly use be fan-shaped upward hole into
Row explosion carries out powder charge using 50 paper tube of powdery emulsifying explosive φ, and explosive payload is big, approximately fills 70-80t medicine every time, and powder charge is existing
Field personnel are more, and cost of labor is big, while labor intensity of workers is big.
And the existing certain free-running property of viscous explosive, and have certain caking property, while possessing excellent explosion property, it can
To adapt to the requirement of underground mine upward hole, dose of doing over again is reduced, mitigates labor intensity of workers.Nothing is had now been developed now
Terraced glutinous pellet explosive, this explosive are to add diesel oil in porous ammonium nitrate and bond sensitizer to mix.It is added
Bonding sensitizer is mixed by methylamine nitrate and polyacrylamide, since the methylamine nitrate of addition is single chmical compound explosive,
Increase explosive cost and security risk.
