Different from the knowledge people usually get from film and television works, in reality, most landmines do not have the ability to release at all. They will explode when stepped on. There is no possibility of demining without being stepped on.

A real mine fuse explodes as soon as it is stepped on. The opened spring firing pin is already in the firing state, and then is loosely stuck in position. It will "stand up" as soon as the unlucky person steps on it. "It passed the bayonet, then hit the explosive powder directly, and quickly detonated the entire mine.

In other words, landmines do not have the "ballpoint pen-like rebound" link imagined by some people. The spring is stuck by the ball detent. After passing this detent, it immediately becomes the trigger. The firing pin of the rifle fired the mine with a click.

We can take a look at the fuse of a mine, and look at the small ball called "striker retaining balls". It is the firing pin bayonet called "firing pin retaining ball", with the firing pin pointing outwards. A very shallow bump was made, which was just caught by the ball.

If a person steps on a landmine, the weight of his body will force the firing pin to pass over this "firing pin fixed ball". In this way, the firing pin will be released and encounter the flash cap that is almost close to it below. , the two explode at the first touch.

Due to the different types of landmines and the different fuse designs in different countries, we can only understand this structure from a principle perspective and cannot make a precise prediction. But all in all, it is impossible for standard anti-infantry mines to have a release principle or structure. Either they will explode when stepped on, or the stepping weight is not enough to release the safety, causing the mine to be unable to release the hammer. At this time, there is no need to worry about "loosing the foot" "Explode", quickly lift your legs and hide away.

Of course, there is another possibility, that is, the mine has been buried underground for a long time, causing the mine body to malfunction. Generally speaking, a landmine cannot be stored for too long. The picric acid-containing landmines popular in World War II will also corrode the iron shell and form picric acid salts, which may cause allergies and explosions. But judging from the landmines left over from war that have appeared from time to time in recent years, it is not necessarily impossible for them to maintain a "quantum" working ability.

In some areas that rely on landmines for defense all year round, affected by various changes in natural conditions, there will also be many scattered malfunctioning mines. They may not necessarily explode when stepped on. This depends on the situation. Character.

So where does "pine hair thunder" come from? Such mines are generally "booby mines" designed on the battlefield, that is, mines provided to engineers or soldiers with special missions to create traps.

In order to be more convenient to use, they are often not designed as specialized integral mines, but are only used in conjunction with other explosives in the form of fuzes. For example, the US military's M1 loose fuze can be screwed on a grenade, or inserted into TNT for use. It can also be directly connected to make a pull or trip mine.

For example, the US military's M1 loose fuze. The picture above shows how to use it with a TNT explosive box. After setting the working mode, plug it in and it can be used. The explosive is just the warhead, and the fuze is the core that determines how the mine explodes.

In fact, people will not use any dark technology on these simple explosive devices. They are just the simplest spring mechanisms.

The secret of the so-called "loose hair" is very simple, it is a cover that springs outward. When using the release function, people will press it under a heavy object after turning on the release function. If someone removes the weight, the cover of the release fuse will be released outward, thereby igniting the bomb.

Therefore, judging from the design environment of Songfa Lei, it is generally designed as a chain explosive device, such as being set up under a normal mine to kill the engineer who triggered the mine, or crushing it under an eye-catching mine. Under the barrier, when people move away from the barrier, blow up the people moving things. Or you can bury them under sandbags, dead bodies, or weapons in the bunker when retreating, posing a huge threat to the opponent as they clean up the battlefield.

After understanding this principle, we will find that the Songfa mine is actually a reverse design. Ordinary landmines explode when stepped on, while Songfa mines do not need to be stepped on and only explode when released.

In other words, even if what you step on is a thunderous pine, you don’t need to do any tricks like inserting a knife or taking off your shoes, as long as you hold down the cover to prevent it from turning outwards. , you can even dig it out and tie it into rice dumplings to play with.

The truth is: Mines are cleared when you don’t step on them. If you step on them, you are hit.

You may have seen this situation in the movie. When the protagonist of the movie stepped on a landmine, he only heard a crisp sound, and then the protagonist looked nervous, stood still, and said: "I I stepped on a landmine.”

After such scenes appear more often, many people think that landmines will explode only after they let go of their feet. However, as long as you think about it for a moment, you can understand that this is true in reality. It's a situation that doesn't exist.

First of all, let's talk about what "demining" is. Demining means discovering the mine without triggering the fuse, and then removing the fuse in time to eliminate it.

If your foot steps on a landmine, it means you have been hit. If you can really step on it and press it with the sole of your shoe as mentioned in the question, and then clear the landmine, it will still be a waste of time. Why bother inventing a demining device? The function of a demining device is to detect unexploded mines in a timely manner.

So, if it is a real situation, if you encounter this kind of thing, it will explode directly if you step on it. You know, the purpose of landmines is to kill people, not for you to step on and play with. of.

Then, let’s talk about why there are such settings in film and television works. This is actually a routine in script writing.

Because you will find that such things are usually linked to the "protagonist", and only the protagonist can have a chance to survive after stepping on a landmine. Look at those supporting characters, they will be stunned when the gunshots are fired. , there is no need for weapons like landmines at all.

So, why is there such a plot for the protagonist? This is actually mainly to create tension for the audience. Because the protagonist must encounter various setbacks on the way to success before there is any content to read on. This is in line with the public's imagination of the growth of a hero, that is: a hero cannot die, but it cannot be too smooth, and this is what he calls a hero; if everything goes smoothly, the audience will probably be unbalanced.

For example, a person in the TV series was born into the second generation of rich people, and was then sent abroad by his parents to study. His parents arranged all the way, and when he grew up, he successfully followed The one you love gets married, has children, has a successful career, and finally develops the family business.

Although this kind of thing does exist in reality, it will mostly arouse the hatred of the audience. The public will think that such people have no setbacks at all, and then compare them with their own lives, stumbling along the way. , this is too unfair.

So, do you think the audience will like this kind of film and television work? Obviously not.

Because the key to film and television works is to try to make the audience's emotions have various ups and downs within an hour, rather than being dull. For this rule, you can compare various excellent works with those with low ratings. , basically the works with negative reviews have no emotional ups and downs. Be well-founded, tell the truth, pay attention to: the truth. Let us look at the world from a rational perspective.

There are two movies about people who step on landmines and clear them by themselves, one is "Assembly" and the other is "Wolf Warrior".

"Assembly"

After Zhao Erdou (played by Deng Chao) stepped on the thunder, Gu Zidi (played by Zhang Hanyu) used a dagger to pierce the military boots and pressed the two ends of the dagger with both hands. Deng Chao Then pull out your feet to get out... The film is talking about an anti-infantry mine made in France. In fact, it looks like an anti-tank mine. It requires more than 180 kilograms of pressure to explode. Deng Chao just stepped on it and raised his feet. It's okay to get up.

So, will situations like the movie scenes appear on real battlefields? This requires understanding the types of anti-infantry landmines. At present, anti-infantry landmines are mainly divided into four types: pressure mines, trip mines, loose mines and artificial fire mines

Among them, artificial fire mines are The so-called "Broad Sword" (Broad Sword) anti-personnel mine is manually controlled and fired, and does not need to be touched before it explodes... Therefore, it is not included in the discussion of the issue.

The main part of the US military M1 loose mine is the mechanical fuze device. As long as the mine body can match the fuze interface, it can be used for mortar shells or even grenades.

As far as movies are concerned, those who step on them and get out of trouble with the help of others should be "loose mines". The detonation principle of the pine mine is: when someone steps on it, it does not explode immediately. The pressure of the step will trigger and release the safety pin of the fuse, putting the mine in a detonation state. When the foot is lifted, the fuse releases the spring and hits the firing pin. The fuse's flash cap detonated the mine.

In "Wolf Warrior", Leng Feng (played by Wu Jing) also stepped on an anti-tank mine, the famous Type 72 anti-tank mine.

But as long as you don’t lift your feet when you step on the pine to trigger the mine, and continue to apply pressure, the spring will not bounce up, it will not be able to trigger the fuse, and the mine will not explode. This also allows other people to assist. The possibility of landmines has been ruled out, but it is rare for movie plots to appear on the battlefield, because soldiers have inertial thinking and then lift their feet after stepping on them. It is also the human instinct to control the balance of the body. In most cases, they will not feel that they have stepped on them. Landmines... So it's very common to be killed and injured by landmines.

Loose mines can be ruled out. If they are trigger mines or mixed mines, they will explode immediately, because their detonation methods are different from loose mines. Trigger mines use an instantaneous firing fuse. When someone steps on it, the firing pin will hit the fuse and detonate the explosive, blowing up the lower part of the calf!

The trip wire is a nylon trip wire tied to the lifting ring. There is a nail at the other end of the trip wire, which serves to fix and tighten the trip wire. When a person's leg is tripped, After reaching this trip wire, the fuze spring will loosen and bounce away. Also with the firing pin downward, the flash cap is fired to detonate the detonator. However, the trip mine has a double mine body structure. The detonator first detonates the high-throwing explosive in the outer mine body, and then the detonator is detonated. The internal mine bomb reaches a height of 3 to 5 meters in the air before exploding. In this way, the prefabricated fragments on the mine body will form a larger area of ????shrapnel damage...from the person to the line, to the mine body to eject, and then to the volley. The explosion time is only 2 to 3 seconds, and the soldiers without knowing it have no time to avoid it, and there is no way to eliminate it, unless there are engineers specially processing the minefield, so trigger mines and trip mines are very important on the battlefield. It won't be excluded like in the movie.

In real battlefields, there have indeed been instances of stepping on pine trees and triggering thunder and eliminating them like in the movies. In January 2016, Ma Xiangqian and Sun Baowei, the Chinese peacekeepers in Mali, Africa, brought other peacekeepers to carry out the mission. During the mission, Sun Baowei stepped on an old-fashioned pine thunder. Our peacekeeping officers and soldiers were well-trained and saw this. They quickly took off their coats and filled them with rocks and sand. At the same time, several other soldiers drew their bayonets and swung them along the heel of Sun Baowei's combat boots. Insert the upper part of the shoe (just like the plot in the movie) and press it with both hands to prevent the mine spring from loosening. Then untie Sun Baowei's bootlaces and pull out his foot to relieve the trap. The other soldiers then press the combat uniforms filled with rocks and sand on the On the bayonet... This example shows that when encountering major dangers on the battlefield, you must not panic. You must calmly know what kind of landmine you are stepping on, and then eliminate it reasonably, otherwise you will lose your life!

As soon as I saw it, I was influenced by the movie and had such questions. In order to create a tense atmosphere, the movie digs a lot of holes for the audience. Many people think that a time bomb will not explode as long as the thread is cut correctly. A landmine will not explode if you step on it as long as you don't let go. If you really want to let go, a hole will be dug next to it. Jump in quickly (there is a natural ditch in "Wolf Warrior"), and if you are fast enough, you won't even be able to damage the fur. This kind of landmine that explodes as soon as the foot is released is vividly called a loose-haired landmine by military fans. There are two other types of landmines that appear more frequently in the movie, one is pressed hair and the other is mixed hair. , that is, if you step on it or accidentally touch the wire connecting the fuse, it will explode. However, these mines are generally prepared for people who want to get their lunch quickly. Only the protagonist is qualified to step on the loose mines.

But in fact, it is a little inaccurate to use pressed, loosened, and mixed to classify landmines. In fact, they only refer to the types of mine fuses. The same type of landmines can be classified using different Fuzes can even be used together. For example, the M1 series of loose fuzes produced in the United States can be used alone with a variety of landmines. In extreme cases, they can even be directly put on a grenade to modify a mine on the spot.

Of course, on truly cruel battlefields, landmines with pressurized and mixed fuses are also the most commonly used. Mixed mines are more practical in jungle combat, and the range of being triggered will be larger. Pressure is used more in highway areas.

As for the loose fuze, it is more about laying booby traps. The layout of this kind of fuze is also more dangerous. It needs to be carefully arranged and is very dangerous. It is generally used to deal with deminers to prevent the mines from being demolished. Therefore, the loose fuze is also It is called an anti-explosion fuse.

In addition, you will not know if you step on a mine with a loose fuse. It will not be like in the movie. The protagonist will be alert as soon as he steps on the mine, and then stop and slowly think of ways to clear the mine. But the reality is that you don’t even know if you have stepped on it, so there won’t be the problem of “if you step on a landmine, just press the mine on the sole of your shoe and take it out before clearing it” as the questioner said.

There are springs in landmines

You can use the spring in a pen as an experimental object

Then press it against the wall or table with your index finger , at this time, press the hand as hard as possible to keep the spring from rebounding. This is the reason why the protagonist in the movie does not dare to move when he steps on it. He cannot let it rebound. As for digging out what the questioner said, the idea is actually feasible, but it is almost impossible in practice, because when you dig a hole, if you dig it too loosely, the mine will fall down, and the spring above will also help. Push it down, and the spring will explode as soon as it unfolds. This can only be guaranteed unless there is very flat and hard rock underground. But mines are never buried in rocks, they are all buried in soft soil.

I wonder if the subject understands the question after I explain it?

You have watched too many movies and TV shows. The first time you step on it, you can only hear your own howling and dying struggle.

For the press-fire type, we generally lie down to the side within 0.3 seconds before the explosion and hide directly in the blind spot where the shrapnel kills.

For the loose hair style, we usually step on it first, then insert a tactical dagger between the sole of the shoe and the mine, press the fuse with your hand, and then ask your comrades to find a big stone to press the dagger. Leave.

We are specially trained to handle bouncing mines. When fighting in the jungle, you must always observe the surrounding environment, especially choose a route with obstacles. There is a time gap when the bouncing mine jumps from the ground to the explosion height in the air. This gap is about one second. During this time, if there is a big tree within three meters, we will roll behind the tree to avoid the bomb before jumping within 0.3 seconds. ; If there is no big tree nearby, either kick it out of the killing range with your feet, or beat it back to the ground with your hands, and then lie down... We directors always have ways to deal with things like landmines.

Can another person help hold the shoe down, loosen the shoelaces, pull out the foot, and put a big stone on the shoe?

Watched too many movies and TV series. Nowadays, landmines will explode as long as you step on them, whether you move them or not.

There are very few people who cause thunder when they are loose, and most people cause thunder when they are pressed. You were deceived by American movies and paid an IQ tax.
