Problems solved by technology

Ordinary explosives can effectively blow open the door as long as they are fixed in place with adhesive tape, but the detonation power of the commonly used concentrated group explosives is too concentrated, which may cause unnecessary damage to anti-terrorist personnel in close combat

Embodiment

[0018] Obstacle 1 is a security door with a width of 86 cm, a height of 192 cm, and a thickness of 7 cm. Breaking the door body requires a total charge of 120 grams of TNT equivalent charge. The combat distance of anti-terrorist personnel is 8 meters. At a safe distance of 8 meters, the single-point dose is 20 grams of TNT, and a total of 6 points are arranged. The length of the nonel is used to delay the time between points, and the detonation is delayed by the variable length method of the nonel between points. After the detonation, the anti-theft door was destroyed as a whole. figure 2 It is the effect diagram after the anti-theft door is broken. image 3 In order to collect the shock wave overpressure history at a distance of 8m from the door body, a total of 6 shock wave overpressure peaks were collected. There is no superposition between the peaks. The maximum peak value is 3.8Kpa. 10ms, 45ms. Figure 4 After the detonation of 120 grams of TNT for the concentrated ...

Abstract

The invention relates to an anti-terrorist differential control method for exploding barriers, belonging to the field of anti-terrorist techniques. When anti-terrorist personnel rescue hostages and chase terrorists, the anti-terrorist personnel are often blocked by limited spaces or firm buildings, thus the anti-terrorist personnel need to break doors, walls, roofs and the like to open up fast channels, thereby winning the opportune time; and meanwhile, because the anti-terrorist personnel combat closely to the terrorists, the personal safety of the anti-terrorist personnel needs to be considered, and especially, the injury to the anti-terrorist personnel caused by explosive air shock waves needs to be considered. The invention is characterized in that concentrated charge is dispersed into multi-point charge, and differential delay ignition is carried out among points. The invention has the advantages of quickly exploding barriers and simultaneously lowering the strength of explosive shock waves in the same distance, thereby reducing the influence on the safety of the anti-terrorist personnel.

Description

technical field [0001] The invention belongs to the technical field of anti-terrorism, relates to an anti-terrorism obstacle removal method, in particular to an anti-terrorism differential control blasting obstacle removal method. Background technique [0002] Terrorists often carry out violent activities in densely populated places and use hostage-taking as a threat. When anti-terrorist personnel rescue hostages and hunt down terrorists, they are often blocked by limited space or solid buildings. It is a close combat, and its personal safety must be considered, especially the damage of the blast air shock wave to anti-terrorist personnel. [0003] Anti-terrorism has carried out extensive research and development on door breaking tools. There are mainly four methods of breaking doors in combat operations: impact, cutting, extrusion and blasting. According to these four methods, people have invented many tools, such as: door-breaking cones, fuse cutters, hydraulic shears, d...
