Description
Technical Field
The utility model relates to an emulsion explosive production quality control field especially relates to an emulsion explosive sympathetic detonation distance suspends testing arrangement in midair.
Background
The gap distance is an important performance index of the emulsion explosive, and is a necessary inspection item in the production and inspection process of the emulsion explosive and used for judging the quality of the explosive. The size of the sympathetic detonation distance reflects the difficulty level of detonation initiated by the explosive under the action of the shock wave, so that the determination of the sympathetic detonation distance of the explosive has important significance for the production, storage and use safety of the explosive.
There are 3 aspects to the cause of sympathetic explosion of an explosive: the first is the impact of the detonation product of the main explosive cartridge on the explosive cartridge to be exploded; secondly, the impact of the thrown object on the explosive cartridge when the main explosive cartridge is detonated; thirdly, when the main explosive cartridge explodes, the shock wave formed in the inert medium acts on the explosive cartridge to be exploded. The following factors are mainly involved in influencing the size of the gap distance of the explosive: the dosage, the explosion heat and the explosion speed of the main explosive roll; constraint conditions of the main explosive cartridge; the connection mode between the main explosive cartridge and the explosive cartridge to be exploded; the detonation sensitivity of the explosive cartridge and the property of the medium in the explosive charging chamber. These factors all have an effect on the detection of sympathetic detonation distance and therefore those factors which do not reflect the nature of the explosive itself must be fixed in the detection in order for the relative comparison of sympathetic detonation distances of the explosive to be accurate.
The conventional gap distance test for the emulsion explosive adopts a sand method, 1 semicircular groove is pressed on a sandy soil ground by a groove pressing plate or a metal or wood round bar with the same diameter as a cartridge, the groove is about 60 cm long, one end of each of two emulsion explosive cartridges is flattened into a tangent plane, the tangent plane is placed into a groove, the centers of the two emulsion explosive cartridges are aligned and respectively used as a main explosive cartridge and a detonated cartridge, wherein a detonator is inserted into a clamping end of the main explosive cartridge, the insertion depth of the detonator is consistent every time, the insertion depth of the detonator occupies about 2/3 of the length of the detonator, the tangent plane end of the detonated cartridge is opposite to the tangent plane end of the main explosive cartridge, and the distance L between the tangent planes of the two cartridges is. Then detonating, observing whether the explosive has residual explosive head or residual explosive after explosion to judge whether the explosive is sympathetic explosion. If the dispensed explosive cartridge is completely exploded, the distance between the two explosive cartridges is increased, and the test is repeated; otherwise, the distance between the two explosive rolls is reduced, and repeated tests until the maximum distance of sympathetic explosions occurring three times continuously is the sympathetic explosion distance L of the explosive roll.
However, this test method does not allow strict control of the consistency of the properties of the material to be tested, since the type of sand, the consistency of the physical properties, such as bulk density, moisture content and the properties of the material underneath the sand layer, etc., cannot be strictly controlled. If the difference of the sympathetic detonation test conditions is large, the sympathetic detonation distance error is large. And when testing, the sand and stone scatter around, only a part is intercepted by the enclosing wall, the sand and stone which fly out of the enclosing wall can not be recycled, the sand and stone need to be replaced regularly, and the resource waste is caused. In addition, in the mountain stone environment is generally established to the sympathetic detonation field, the seismic wave that adopts the sand ground law to carry out the sympathetic detonation distance test for a long time and produce has great influence to the stability and the fixity of peripheral mountain stone, often has the mountain stone to fly off from the mountain and fall, forms very big potential safety hazard and environmental impact.
