Cross sand bed to separate, the explosive of feeling immediately is provided with secondary priming, and the secondary priming is provided with detonator, and the explosive of feeling immediately is with sand
Between layer, secondary priming and feel immediately between explosive, separated by aluminium flake between detonator and secondary priming, the detonator and PVC
Space filling concrete between pipe.
Preferably, the top of the sand bed is put down stifled top and is maintained an equal level with PVC.
Preferably, the detonator is 8# standard Nonel detonators.
Preferably, the 8# standards Nonel detonator is located at the shaft core position of pvc pipe, the 8# standards Nonel detonator
The length of detonator is 5-10m.
Preferably, the cement is completely covered in detonator.
Preferably, the secondary priming adopts the ammonium nitrate of ring trimethylene three.
This device carries out the process and principle of underwater explosion test experiments:Research shows that the explosive of small pit goaf is being subject to
Complete detonation is can be achieved under conditions of certain constraint.Therefore, in limited water field blast pond, a certain depth is felt immediately
When explosive underwater explosion is tested, first a certain amount of sand is put into pvc pipe, is maintained an equal level with flat stifled top to height, now, felt immediately
Constraints suffered by explosive is consistent, and is put into an aluminium flake into wherein, is pressed lightly on so as to smooth;It is then placed in one
Quantitative desensitized explosive, it is desirable to which each place is uniform, seamless, places into aluminium flake, presses lightly on, and holding surface is smooth;Afterwards
A certain amount of RDX is added thereto, aluminium flake is put into, is pressed lightly on;8# standard Nonel detonators are put into the middle of pvc pipe,
It is required that detonator length is at least 5m, and keep vertical;The cement for just having mixed is poured into pvc pipe, it is desirable to fill up, height
More than cap length;When concrete setting, with exploder detonation tube detonator.
The invention has the beneficial effects as follows, using after this restraint device, realizing under conditions of small pit goaf, feel immediately explosive in
This result of complete detonation in underwater explosion test such that it is able to measure its workmanship ability, and acting ability is that measurement explosive is quick-fried
The important performance indexes of broken power, measuring for the result is beneficial to the energy for making full use of explosive, improves the Jing of engineering explosion
Ji benefit.
