Mine-clearing line charge

Mine-clearing line charge is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mine-clearing line charge rather than just read about it. In short: A mine-clearing line charge (abbreviated MCLC or MICLIC; pronounced or "mick-lick") is a device used to create a breach in minefields under combat conditions. While there are many types, the basic design is for many explosive charges connected on a line to be projected onto the minefield and then exploded, detonating any buried mines, thus clearing a path for troops to cross.

Key takeaways

  • Mine-clearing line charge belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Mine-clearing line charge to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Mine-clearing line charge from memory before moving on to harder problems.

Reference excerpt

A mine-clearing line charge (abbreviated MCLC or MICLIC; pronounced or "mick-lick") is a device used to create a breach in minefields under combat conditions. While there are many types, the basic design is for many explosive charges connected on a line to be projected onto the minefield and then exploded, detonating any buried mines, thus clearing a path for troops to cross. The system may either be human-portable or vehicle-mounted. Man-portable MCLCs are primarily used to clear smaller paths for dismounted infantry while the larger vehicle mounted are used to clear paths for combat vehicles. The systems do not guarantee clearance of all types of mines.

History The British and Commonwealth developed their systems during the Second World War. The Canadians developed "Snake", an oversized application of the Bangalore torpedo in 1941 to 1942. A more flexible development was "Conger", developed in 1944, a tube that could be fired across the minefield and then filled with explosive before detonation. Conger was a 2-inch (51 mm) woven hose launched by a five-inch (127 mm) rocket. The tube and rocket were mounted in a Universal Carrier which had been stripped out to reduce it down to an armoured tracked trailer that could be towed by a tank, often a Churchill AVRE. The rocket was fired, trailing the hose across the area to be cleared. Compressed air was then used to pump the liquid explosive – just over a ton of "822C" nitroglycerin – into the hose before it was detonated. Conger was used in Normandy where there were instances of premature detonation. In October 1944 a Conger prematurely exploded in Ijzendijke, the Netherlands, killing 57 British and Canadian Soldiers. In the 1950s the British introduced Giant Viper towed MICLIC. In 1991, during the First Gulf War (a.k.a. the Persian Gulf War) MICLICs, such as the Giant Viper, consisted of rocket launched lines containing roughly 800 kilograms of explosives, stretching some 100 meters long. These MICLICs were used by Coalition forces to penetrate extensive Iraqi minefield along the Saudi-Kuwait border. During the South African Border War, South African forces employed the use of the Plofadder system to clear paths through Angolan and Cuban minefields.

Current use

Systems in current use include the British Python minefield breaching system, which can clear a 7.3-metre (24 ft) wide by 180–200-metre (590–660 ft) long path, and the American M58 Mine Clearing Line Charge, which can clear an 8 m wide by 100 m long path. Both are large, heavy systems that are deployed in a vehicle-towed trailer. The US Army also uses the Antipersonnel Obstacle Breaching System, which clears a path 0.6 to 1.0 meters by 45 meters, and is light enough to be carried by two soldiers. There have been reports of Russian forces using the UR-77 Meteorit MICLIC systems in Syria as offensive weapons to destroy buildings during urban fighting.

Countermeasures Some modern mines, such as the Italian SB-33 mine, have a fuze mechanism that detonates the mine if subject to gradual, steady pressure, but locks the fuze if subject to a sudden shock. Such mines are resistant to clearing by line charges.

Worked examples

Example 1 — a first encounter with Mine-clearing line charge

Start with the simplest possible case. Write down what Mine-clearing line charge claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mine-clearing line charge before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mine-clearing line charge ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mine-clearing line charge

In research
Mine-clearing line charge appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Mine-clearing line charge in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Mine-clearing line charge is common in secondary-school and first-year university syllabi. It links to neighbouring topics English inventions, Mine warfare countermeasures, so understanding it makes those chapters shorter.
In everyday life
Look for Mine-clearing line charge outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
