Oranje Nassau IV

Oranje Nassau IV is a engineering 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 Oranje Nassau IV rather than just read about it. In short: The Oranje Nassau IV (located in Heerlerheide, Heerlen) was the last and smallest mine exploited by the Oranje Nassau Mijnen. It began as a ventilation shaft for Oranje Nassau III, and in 1910 construction started on a mine shaft.

Key takeaways

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

Reference excerpt

The Oranje Nassau IV (located in Heerlerheide, Heerlen) was the last and smallest mine exploited by the Oranje Nassau Mijnen. It began as a ventilation shaft for Oranje Nassau III, and in 1910 construction started on a mine shaft. However, the construction was halted and only resumed in 1919, with the mine becoming operational in 1927. Underground, the mine was connected to the Oranje Nassau III and, for safety reasons, also the Staatsmijn Hendrik. In 1966 it became the first of the Oranje Nassau mines to close, though mining activities continued until 1973 via the Oranje Nassau III. The mine was 740 metres (2,430 ft) deep and produced 13,754,000,000 kilograms (3.0322×1010 lb) of coal during its operational period. The terrain is now used by the Sigrano, a silver sand mine operated by Sibelco.

Worked examples

Example 1 — a first encounter with Oranje Nassau IV

Start with the simplest possible case. Write down what Oranje Nassau IV claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Oranje Nassau IV 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 Oranje Nassau IV 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 Oranje Nassau IV

In research: Oranje Nassau IV appears in engineering 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 Oranje Nassau IV 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: Oranje Nassau IV is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures in Heerlen, Coal mines in the Netherlands, Limburg (Netherlands) geography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Oranje Nassau IV 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.
