Tonglushan mine

Tonglushan mine 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 Tonglushan mine rather than just read about it. In short: The Tonglushan mine is a Chinese copper mine located 1.5 kilometres (0.93 mi) east of the city of Daye in Hubei province. The mine is operated by China Daye Non-Ferrous Metals Mining Ltd., a subsidiary of China Nonferrous Metal Mining Group.

Key takeaways

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

Reference excerpt

The Tonglushan mine is a Chinese copper mine located 1.5 kilometres (0.93 mi) east of the city of Daye in Hubei province. The mine is operated by China Daye Non-Ferrous Metals Mining Ltd., a subsidiary of China Nonferrous Metal Mining Group. On 12 March 2017, the open-pit mine was the site of a tailings dam failure which killed at least 2 workers. The operating company, China Daye Non-Ferrous Metals Mining reportedly incurred a 45.2M Yuan loss due to the incident after an investigation launched by the government of Huangshi city. Mining and illegal extraction of material under the dam was blamed for its failure.

Worked examples

Example 1 — a first encounter with Tonglushan mine

Start with the simplest possible case. Write down what Tonglushan mine 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 Tonglushan mine 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 Tonglushan mine 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 Tonglushan mine

In research: Tonglushan mine 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 Tonglushan mine 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: Tonglushan mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics China geography stubs, Copper mines in China, Floods in China, so understanding it makes those chapters shorter.
In everyday life: Look for Tonglushan mine 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.
