MON-100

Encyclopedia : M : MO : MON : MON-100

The MON-100 is a circular, sheet metal bodied, directional type of anti-personnel mine designed and manufactured in Russia. It is designed to wound or kill by fragmentation and resembles a large bowl.

Design

The MON-100 mine body has a smooth, well finished appearance with a cloth handle mounted on the upper edge, it is usually attached to a mounting shackle by wing nuts on either side of the mine body (the shackle is connected to a spike for securing the mine to buildings, trees etc.). The concave face of the mine has a detonator cavity in its center (this is the side aimed at the target).

The mine contains 2 kg of explosive to propel 400 steel rod fragments to a lethal range of 100 m, at maximum range the spread of the fragmentation is 9.5 m. The mine alone weighs 5 kg but with the shackle and mounting spike the weight is 7.53 kg. The MON 100 can be command actuated using a PN manual inductor attached by demolition cable to an EDP-R electric detonator. It can also be actuated by a variety of booby trap (BT) switches including:

The MON-100 will usually be mounted above ground level on the surface or up in trees to give the greatest dispersion of fragments. The mine can be located visually or with metal detectors under most field conditions. Depending on its actuation method the MON-100 may be resistant to blast overpressure from explosive breaching systems like the Giant Viper and M58 MICLIC. The mine is also produced for export to Poland.

Specifications

Operation

Arming

Once the mine is laid and secured (normally by pressing scissor legs into ground or attaching to objects with adjustable clamp), is aimed using a “T” shaped aiming stick. Once the mine is in position proceed as follows, depending on the initiating method chosen:

Command Detonation

  1. For command detonation using the EDP-R detonator, run the firing cable from the firing point to the mine ensuring that the leg wires at the firing end are shunted and grounded. Inspect the cable to ensure its serviceability and test continuity of the detonator.
  2. Attach the detonator to the firing cable and test circuit for continuity observing approved grounding/bonding procedures for a minimum of 10 seconds. While leg wires are opened all radio transmissions must cease.
  3. Insert the detonator into the detonator cavity. Re-adjust the aim if necessary and complete the camouflage of the mine.
  4. Return to the firing point and after rechecking continuity; attach the firing mechanism to the firing cable.
Note: If using the NM electric initiator with the MD-5 detonator in the command detonation mode the sequence is the same.

Tripwire Activation (MUV fuze)

  1. If the mine is to be set for tripwire activation it will likely use the Russian MUV series of fuze. Check the condition of the fuze and confirm its serviceability.
  2. Screw the MD-2 or MD-5M detonator assembly into the end of the fuze.
  3. Secure the tripwire to an anchor and run it to the fuze. This trip wire once secured to the pull pin must be a loose trip wire to prevent inadvertent pull on the pin. Attach the wire to the pull pin and finish camouflaging the mine.
  4. If using either the MUV 2, 3 or 4, remove the delay arming pin at this time and retain.

Tripwire and detonating cord

  1. Alternatively, if the mine is to be set for tripwire and detonating cord (det cord) activation it will likely use the Russian MUV series of fuze or the VPF igniter and an MD-2 or MD-5M detonator assembly, ZT detonator and variable length of detonating cord.
  2. Check the condition of the fuze and confirm its serviceability. Secure a short length of detonating cord(30-40 cm) to the MD-2 or MD-5M detonator and screw the detonator assembly into the end of the fuze.
  3. Setup the fuze and tripwire as per normal drills appropriate for the activation site.
  4. Insert the ZT detonator into the fuze well of the MON-100, confirm its aim and complete the camouflage of the mine.
  5. Carefully remove the arming/safety pin from the fuze and connect the two lengths of detonating cord together and carefully complete the camouflage of the detonating cord.

Breakwire Activation (MVE-72 fuze)

  1. Position the MVE-72 electronic fuze in close proximity to the mine and remove the blue plastic spool on the top of the fuze, remove the three Bakelite caps and inspect the Breakwire jack, the NM fuze well and the pull friction igniter cord for the pyrotechnic delay.
  2. Remove the battery holder and insert new or check the existing battery and replace the battery holder.
  3. Carefully lay the breakwire around the area to be covered and insert the breakwire jack into the breakwire jack socket.
  4. Screw an MD-2 or MD-5M detonator assembly into the end of the NM fuze and insert the threaded ring into the NM fuze well.
  5. The friction switch cord is pulled beginning the pyrotechnic delay, the mine is armed after 50 to 180 seconds. If the wire is broken the fuze detonates the NM fuze.
  6. Carefully insert the NM fuze into the mines detonator well.
Note: If the wire is broken the fuze detonates the NM fuze. Handle the breakwire with extreme care.

Neutralizing

Command Detonation

  1. Always secure the firing system of an electrically actuated mine by ensuring that both the mine, the command wire and the electrical firing device are under observation and physical control of friendly forces.
  2. Once the exact location of the firing device is determined, check the immediate ground around the control site for signs of boobytraps or anti-disturbance devices.
  3. Remove the firing device from the system, then shunt and ground the command wire.
  4. Approach the mine from the rear quarter following along the command wire (ensure to clear the ground along the wire for blast type A pers mines).
  5. Once at the mine, check the immediate surroundings for signs of anti-handling (AH) or anti-disturbance (AD) devices (if either are detected blow the mine in place).
  6. Ensure that no other means of actuation are present on the mine (the mine is now neutralized).
Tripwire Actuated Only
  1. Follow the tripwire to both ends clearing the ground along the wire for other types of anti-personnel mines.
  2. Check the immediate ground for signs of boobytraps or anti-disturbance devices. If booby trap, anti-handling (AH) or anti-disturbance (AD) devices are detected or suspected blow the mine in place.
  3. If an MUV series fuze has been used, secure the safety pin in the MUV series fuze using thumb and forefinger.
  4. Cut the tripwire 20 cm from the fuze and wrap the excess around the fuze to secure the pull pin. The mine is now neutralized.

Breakwire Actuated

The MVE-72 cannot be neutralized.

Note: For dual actuated mines, if the electrical system is manned, it is the primary threat and it must be dealt with first by following the drill for command actuation. If the firing system is secured then the tripwire is the primary threat and it must be dealt with first.

Disarming

Lift the mine from the ground and unscrew the fuze. If the MVE-72 fuze was used, unscrew the threaded ring from the NM fuze well and remove the fuse from the mine. Remove the MD-2 or MN-5M detonator from the NM fuze. Disconnect the Breakwire Jack and discard. Remove battery and discard IAW HAZMAT disposal regulations and destroy the MVE-72 fuze body by smashing with a hammer. Discard parts. Store explosive components separately for future disposal observing proper storage regulations and compatibility segregation.

Disarming (demining)

Hazards

Because it is a directional type of mine, it should never be approached from the front, always front the rear or side.

The MON-90 is known to be used with the VP13 seismic controller which prevents close approach for any clearance operations. If the mine is encountered with any type of electrical wires running from it, secure both ends of the wire before approaching the mine, because it could be linked to another mine or other booby trap device.

On detonation the mine will normally propel lethal fragmentation to a range between 75 and 125 meters. The actual hazard range for this mines can be as high as 160 metres (this is directly in front of the mine, fragmentation range and density drop off to 125 meters to the sides and rear of these mines). Always be alert for well concealed blast mines laid along tripwires (don't get tripwire fixation).

Disposal

Whenever possible the MON-100 mine should be blown in place (BIP) using a 0.5 kg explosive charge placed in a way to disrupt the fragmentation pattern and force the fragmentation toward the ground.
