Oranje Nassau II

Oranje Nassau II 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 II rather than just read about it. In short: The Oranje Nassau II was a Dutch coal mine located in Schaesberg. The mine was in operation from 1904 until 1971.

Key takeaways

Oranje Nassau II 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 II to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Oranje Nassau II from memory before moving on to harder problems.

Reference excerpt

The Oranje Nassau II was a Dutch coal mine located in Schaesberg. The mine was in operation from 1904 until 1971. It was the second of four mines collectively known as the Oranje Nassau Mijnen. When the first coal was extracted in 1904, high production levels were not yet achieved. The mine was not connected to the railroad and the coal had to be hauled to the Schaesberg station by horse and carriage. In 1906 the mine was in full production as the railways to Heerlen were finished. This railway was also used by the Staatsmijn Wilhelmina. Until its closure, a total of 34,065,000 tons of coal were brought to the surface. The highest production was reached in 1930 with 687,000 tonnes. In the last year that the mine was still in production (1970) 506,000 tonnes were won.

Worked examples

Example 1 — a first encounter with Oranje Nassau II

Start with the simplest possible case. Write down what Oranje Nassau II 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 II 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 II 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 II

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