A little help in building demining system

[ivconic]

Modern mines. If you become too good at detecting them want the manufacturers of them change their design to detect the detector.

That's good point!
I assume manufacturers of mines are constantly being updated with latest detection technology.
It's a never ending race.
Though i think mine manufacturers are in huge advantage because detection technology can not evolve that fast.

Manufacturing landmines generally relies on proven* designs from late '80s to '90s. In that sense they are like many of the forum favourite detectors here But it is for the same reasons! They are usually easy enough to replicate, the parts themselves can be worked with by hand, and they are generally more than enough to satisfy their users.

While minimum metal mines are already infernally hard to find, there are already fully nonmetallic landmines that cannot be found by inductive metal detectors - unless working in horrible terrain with mis-tuned GB and knowing where to seek. There are other methods like ground penetrating radar when the weather is nice, and molecule-sniffing by expensive sophisticated machine or inexpensive sophisticated animal. Eventually it falls down to manual probing in order to pinpoint the landmines and UXO.

That "never ending race" is not exactly a fast race, there are still large stocks of '50s to '80s landmines waiting for their potential buyers in the warehouses of people who will sell, and they are dirt cheap compared to manufacturing "modern" mines. Their intended targets usually do not have the means to find them, and even if they did, it would generally be work that takes many minutes per square meter to probe with any kind of confidence.

For alot stuff MDs are no longer choice No.1.

The docu series:

Blood Road Bomb Squad
and:
Bomb Patrol: Afghanistan

more:
https://en.wikipedia.org/wiki/List_o..._documentaries

are showing how special forces clear the roads of Afghanistan from selfbuilt crap
which also does not contain alot metal, only some wires which are buried together
with some 10-20 liter cans full of dangerous mixtures pretty deep.

They use remote controlled roboters to place a charge or special
protected tank-vehicles which are intended making this stuff to go off.


@ Hammerhead
The most mines from WW2 are easy to detect and there exists documentation, too.
And probably the most of them meanwhile are out of function anyway. But be careful!
If there is no rain at the Sahara it might not rusts and still is in top shape after 70 years.



I would never mess around with any metal-detector, even if its super-sensitive
for small stuff, concering this new unpredictable plastic stuff. The risk is too high.

btw. a big problem is: The smaller the metal inside the mine, the more junk metal objects
those are finding who are searching for these things.
This can go up from 1:100 to 1:1000 depending on how polluted is the area with other stuff.

Yesterday I did post already the link to a free ebook and today the next - about demining:

That's true.
Only way i can think on for successfully detect and locate modern mines is something like GPR or similar technology.
Something which will "recognize" any "alien" shape and body in surrounding soil.
Shape which supposedly is not belonging there in soil, by getting it's rough contours on the screen.
So it's something like GPR.
...
But than there is another possible danger; mine mechanism may be made to react on magnetic or rf field!
All the "invasive" methods are under such risk.
Only an "non-invasive" detection method may overcome all the mentioned issues.
Which one?



P.S.
Collection, mostly collected with Fisher 1265:

[Orbit]

Maybe passive magnetometer ?!

[Davor]

Maybe a flock of sheep?

[ivconic]

Maybe a flock of sheep?

Which will end up with a huge pile of roast sheep!
...
No, i was rather thinking on something similar to what Orbit mentioned.
Not exactly the magnetometer (obviously firing pins are having bad magnetic properties) but something similar which can be classified under the category "non-invasive".
Maybe something similar to ulf locator technology?
Passive reception of reflected distant rf signals with high sampling resolution.

The most secure way is "intel" or info.

2 days ago I saw the german docu: "Bomb-legacy of 2nd worldwar".
There were acid-fuses and clockwork-time-triggers and many so called "fireworkers" died
until they knew excactly with what kind of unexploded bomb they had to deal with!

Some also have fuse-remove-protections.

Personally I would force those who buried the mines to clear them!
Why others should do their dirt work?
Because civilians wanna have back their once owned land?!

Second option: use roboters or other devices to make them "bumm"
no experiments with humans.

A not really new method is using trained mine-rats to sniff those devices out.


Realistically seen:
Never try to open any war leftover thing which looks explosive!

If somewhere are war-remnants to find the chances are "good" that there is more.

Download pdfs about the 2nd world war and what was used so you can at least
estimate which objects are much more dangerous than rusty old rounds.
Of course only if you live at a region which was involved!

visit google, type the following and download the pdfs:

humanitarian demining pdf


If you are at a region with still not removed modern mines - keep the hell away from it!
Without experts knowledge your life could be very short there.
And there is more than just mines which could be highly dangerous.


@ ivconic
Nice collection - you should get a bagde for making your homeland more secure again,
so mushroom-gatherers don't fly high as an atomic-mushroom!


btw. one of the best education about WW2 "mines" still is shown at a private video from an ukrainian treasure-hunter babe:

Especially part 4 and 5 is about unexploded world war 2 stuff.
Of course this is a paradise for thrill-seekers!
Don't do it if you are scared at night if the lights are out!
Play Resident Evil, Silent Hill or Alone In The Dark first!

You're life is so boring and dull that you wanna commit suicide?
Get a metal-detector and search for UXO and you can have solved
both problems at once !!! *just joking*

Normally those who have spreaded all this stuff are responsible to find it,
not civilians. I really hate it if I see mamed children just because those
who caused this whole sh*t do nothing to remove their caused dirt!
And within 20 years 1000s of people still die after wars just because of the
deadly remains!
