1.3.1 117.-1 Demolition Pipe (USSR)
Description
The factory-produced demolition pipes consist of connectable metal
pipe compoents which are filled with explosives. With the help of
bayonet joints any number of these pipe components can be connected
to form an explosive device. A conical terminating sleeve prevents
it from getting hooked up on something, for example in a wire obstacle.
Fuse-well threaded caps are affixed on both ends of the demolition
pipe components for insertion of one detonator each, whcih are triggered
electrically or by other nonelectrical standard initiators.

Description
TWO 82-1 demolition pipes make up the UZ-2 system, and three make up
the 06-S system. The two or three-stranded row charges are connected
by clamping rings.
To protect the row charges from being hit by light infantry weapons,
a pyramid-shaped shield may be installed at the head of a row.
For reasons of stability, the individuals pipes can be connected before
they are shoved forward. For a maximum length of SO meters for the two-
stranded version and 100 meters for the three-stranded versions.

1.5 Bulk Exnlosives
In the Warsaw Pact bulk explosives are mainly used for ground detonations.
An exception to this is a formative explosive substance.
PERMDN 5
PERMON 3 is a powdery ammonite explosive with increased water-resistance
It is a soft, Powdery, light-red dust and Consists of 90% ammonium nitrate,
6% TNT, 4% wax, paraffine, colorants and water-repellant additives. It
is packed in waterproof sacks made of polyethilene, each one weighing 25 kgs.
Two sacks each are stored in a wooden container.
If PERHON 3 is used instead of TNT, the required amount is explosive
material is increased 1.5 - 2 times. The minimum amount for confined
charges is 500 g.
Other characteristics:
Density aprx. .995 g/m3
Detonation velocity 31500 - 5,000 meters/s
Explosive Substance P1NE10
This plastic explosive is about 50% more effective than TIC. However,
its composition is unknown. The plastic substance can be adjusted to
the object. Detonator holders are not necessary.

3.1 Detonating Cords
3.1.1 General (WP)
The detonating cord consists of a highly explosive core composed of PETN
or BOX in a textile jacket. It is coated with a thim layer of bitumen,
which is coated by a second outer layer of textile which again is covered
by a layer of waxed rubber or synthetic material. The detonating cord
transmits a wave from one point to the other with a velocity of 6,000
to 7,000 meters/s. Even if one end of the detonating cord is lying under
water, the cord can still be ignited from the dry end. Although in low
temperatures the detonating cord does not lose any of its detonating
characteristics, its outer coat becomes still and cracks when bent. The
detonating cord is used to ignite explosive charges with the detonation
transmitted through a detonator. The detonating cord may simultaneously
transmit the wave to any number of explosive charges.
Detonating cord used by the WP is usually produced with PUN. Previous
types of detonating cord were produced with white, red or green plastic
coating. Today all of them are produced with red coating. Soviet detonat-
ing cords are marked with the letters "OSh" and following numbers, while
the Czechoslovakian versions bear the letters "Np" before their identifica-
tion numbers.

3.3.2 Pressure Fuses
3.3.2.1 MV-5
Description
The MV-5 pressure fuse is the most frequently used fuse for igniting anti-tank
mines.
The fuse casing is made of metal; a new variant with the designation MV-5K is
constructed of synthetic material.
Pressure exerted on the fuse moves the pressure cap downwards and in this
process the spring is thightened.
As soon as the priming energy is reached, the safety pellet will slip into
the bulge of the pressure cap. THereby the plunger will be released, hit
the primer cap below, and ignite without delay.
There are no additional safety features.
Shorter detonators are used for particularly flat mines.

safety pellet. By exerting pressure on the case cover, the pressure cap
will move downwards until the safety pellet slips into the bulge of the
pressure cap.
Thus, the plunger is released and the ignition is tiggered.

The Ro-8 pressure fuse is activated by a safety splint sitting on top
of the fuse case, near the holder of the pressure sensing device. After
the safety splint is removed, the plunger is held by safety pellets.
If vertical pressure is exerted on the sensing devices, the holder of
these devices will push the safety pellets into the bulges of the fuse
case and will thus release the spring-loaded plunger. The plunger will
then hit the primer cap and the device ignites.

Description
The chemical pressure fuse, made of synthetic material and bakelite,
is used in the plastic anti-tank mine PM-60 (GDR), if the latter is
layed by hand.
As soon as the release energy on the pressure piece is exceeded, the
acid capsule will burst and light the primer substance. The latter
will transmit the ignition to the detonator.
The removable ring around the pressure piece sitting on top of the
case secures the pressure fuse during transport.

3.3.3.2 MUV-2 (USSR)
Description
The MUV-2 pull fuse is an advanced development of the MUV pull fuse.
The MUV-2 functions according to the same principle as the MUV (see
3.3.3.1) but on activation delay is built into the device as an add-
itional safety feature. After it is activiated, a thin cutting wire
at the end of the plunger cuts a soft metal plate and thus delays the
ignition process. This accessory prevents accidental tripping during
transfer, concealment and activation.

3.3.3.3 VPF (USSR)
Description
The VPF pull fuse is composed of three main parts, the fuse container,
plunger and trip component. In a dormant condition, the spring-loaded
plunger is held by a locking pin.
When activated, the pellet sitting at the end of the plunger is held
by the claw-like lower portion of the trip component. As soon as the
release energy is exceeded, the pellet is released and the spring-loaded
plunger initiates the ignition. The trip component reacts to the energy
pulled through the pull rings; side pressure may also initiate the fuse
through an extension bar attached to the trip component.
The fuse can be attached to the object with a special holder; it may
also be used in water.
The detonator can only be inserted on the operational site.

Description
The MVSh-46 tilt fuse resembles a pull fuse. Through the steel cylinder
and the plunger retainer rod the force bearing upon the tilt handle is
transformed into a pulling force.
If a force bears upon the tilt handle from any direction, the plunger
retainer rod will be lifted together with the retaining device for the
safety pellets. In this case the safety pellets will fall into the
slot and will release the spring-loaded plunger, which will initiate
the ignition.
There are no safety accessories.

3.3.5 Delay Fuses
3.3.5.1 UZ-16-T Clockwork Fuse (GDR)
Description
The UZ-16-T clockwork fuse is composed of the following main parts:
- Case with cap
- timer with initiating device
- safety mechanism
- plunger with plunger spring
The delay can be set in 2-hour intervals for up to 16 days. For setting
the delay time, the cap is unscrewed, the fuse is removed from the case
and the delay time is set. The safety mechanism is activated auto-
matically as soon as the cap is removed. THus, the fuse is unarmed.
This safet mechanism no longer works for delay times of less than 5
hours. After insertion of the fuse into the case and attachment of
the cap, the fuse is activated.
The clockwork runs at 150 rpm and moves the tripping disk, which is
connected to the adjustable dial. As soon as the slot of the tripping
disk catches the tripping lever, the release pin will release the spring-
loaded plunger and initiate the ignition through the primer cap.
Activation
The exact ignition time cannot be set from outside. If the cap of the
UZ-16 T is unscrewed, the safety mechanism will be activated and the
fuse is secured. However, if the window shows that the ignition will
take place in 5 hours, the safety mechanism does not work when the cap
is unscrewed. In this case, the release mechanism and the plunger must
cautiously be pulled out of the tube. There is no other way to secure
the fuse.

The UZ-60-T clockwork fuse consists of the following Main parts:
- Case with cap and cap lock
- Timer with initiating device and securing mechanism
- Plunger
To set the delay time, the key is unscrewed. The timer will be set
with the key through an opening in the bottom. After the fuse cap
is removed, the desired delay time of up to 60 days, with a maximum
accuracy of 12 hours, will be set with the clock hand. The set delay
time can still be changed. The key is inserted through the primer
cavity in order to push the plunger upwards until the safety mechanism
is caught by the plunger. Thus, the plunger spring is thightened.
After the clockwork has reached the set time, the hand presses the
safety mechanism out of the slot of the plunger. The spring-loaded
plunger strikes the primer cap and thus initiates the ignition.

mechancial delay placed in a metal container. A time disk and a
hand are located directly under the cover. Arrows on the dial in-
dicate the direction in which the hand moves. The hand is used for
setting the desired delay time of up to 10 days. A winding stem
with key is attached to the bottom of the fuse container.
Two cable to be connected to the electrical explosive circuit pro-
trude from the bottom of"the tylindrical container. After expira-
tion of the delay time, the clockwork release lever through the
spring-loaded contact closes the circuit and thus initiates the
ignition.

ChZ-35 clockwork fuse is used for the electrical initation of explosive
devices and mines.
The ChZ-35 exists in either a cylindrical or a square shap, but the
functioning in both is identical. With six hours' deviation, delay
times of up to 35 days can be set with this fuse.
With the help of the set-knob attached to the hand of the clock, the
desired delay time can be set. In addition to the dial, the winding
stem and its key are located under the cover of the ChZ-35 time fuse
clockwork. When the delay time is over, the clockwork release lever
over a spring-loaded contacy closes the circuit and it is ignited.
It is possible to dectivate the ChZ-35 by cutting the electrical wires,
one after another.

3.3.5.7 EKhP Electro-Chemical Delay Fuse (USSR)
Description
The EKhP electro-chemical delay fuse is mainly used as a delay fuse
in detonation circuits in order to increase the safety.
The fuse consists of a spring-loaded contact which is kept open by
a copper capsule. If electricity flows between the copper capsule
and the surrounding copper sulfate solution, the copper capsule is
dissolved and releases the spring-loaded contact. The contact closes
the explosive circuit and it ignites.
The delay time depends on the temperature of the environment. At higher
temperature it is 10 minutes, at lower temperatures up to 4 hours.

The EKhV electro-chemical delay fuse amy be inserted into an electrical
circuit as well as directly into mines or explosive device.
In the bakelite container, a copper wire holds a spring-loaded plunger.
At the same time the plunger serves as contact for the explosive circuit.
When exposed to electricity, the surrounding copper sulfate solution
will melt the copper wire and the spring-loaded plunger/contact will
close the explosive circuit or will initiate the primer cap of the de-
tonator MD-2. A build-in 1.4 V dry battery serves as the power source.
Depending on the environmental temperature, the delay time varies from
1 day to 120 days. There are no safety accessories.

3,3.6.1 V:-1 Vibration Fuse (USSR)
Description
The )77.-1 vibration fuse sits in a round cardboard container. Its in-
terior consists of a hollow, thick-rubber disk. In the disk's center,
a Y-shaped metal vibrator is suspended horizontally from three horiz-
ontally attached fine spiral springs. A contact screw, to which also
one of the two leg wires is connected, vertically protrudes into the
hollow space through the upper rubber layer. It rests a short dis-
tance from the vibrator, The second leg wire is connected to one of
the fine springs so that the circuit is broken only by the small space
between the vibrator and the head of the contact screw. Both leg
wires are connected to an electrical circuit for initiating the explosive
charge. With traffic passing nearby, the vibrator begins to shake until
it touches the contact screw. This way it closes the circuit and
triggers the explosion of the detonator.

3.3.6,2 Ohl': Vibration Fuse 11255R)
Description
This vibration fuse was developed by the Soviets primarily for their
DM road mine. However, the GhVD is also suitable for other explosive
charges or improvised mines, and it is most effective on bridges and
in difficult terrain where vehicles produce strong vibrations.
The fuse consists of a cylindrical metal container enclosing a clock-
work safety mechanism and two (i.e. a vertical and a horizontal)
aluminum-coated sprial spring vibration contacts as well as a 4 Volt
dry flashlight battery. The colckwork safety mechanism activates the
fuse only after 4 minutes have elapsed. Vibrations make the spiral
springs shake until one of them touches one of the two contacts. This
closes the circuit and the detonator explodes.
Once it has been activated, the ChVZ is tremendously sensitive. And
if there is no possibility of cutting the short wires leading to the
detonator without moving the fuse or even shaking it slightly, it
should never be deactivated manually.

3.3.6.3 UV}(-1 Auto-Fuse (USSR)
Description
The UVK I auto-fuse was specially developed for the bounding-type OZN
mine in border zones. This auto-fuse consists of a cylindrical metal
container enclosing the charge, a delay device, a detonator and a
booster charge. The device has two holes: One of them is usually
closed by a plug into which a mechanical fuse can be inserted. The
second opening is provided for the wires of an electrical detonator,
in case the fuse is to be electrically initiated. The electrical
or mechanical initiation will ignite the charge, which will ignite
the delay device. The latter will them burn-through in order to ignite
the detonator and thus start the firing sequence.
