Hachinohe mine

Hachinohe 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 Hachinohe mine rather than just read about it. In short: The Hachinohe mine (八戸鉱山, Hachinohe Kōzan) is a limestone quarry in the city of Hachinohe, Aomori Prefecture, in the northern Tohoku region of northern Japan. It is operated by the Sumimetal Mining Company.

Key takeaways

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

Reference excerpt

The Hachinohe mine (八戸鉱山, Hachinohe Kōzan) is a limestone quarry in the city of Hachinohe, Aomori Prefecture, in the northern Tohoku region of northern Japan. It is operated by the Sumimetal Mining Company. The mine is the lowest point in Japan at 170 metres (560 ft) below sea level, and digging still continues. The open pit has a north–south length of approximately 2 kilometers and an east–west width of 800 meters. The limestone excavated is transported by a 10 kilometer pipeline with belt conveyor to Port of Hachinohe. The mine is locally nicknamed the "Hachinohe Canyon."

Worked examples

Example 1 — a first encounter with Hachinohe mine

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

In research: Hachinohe 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 Hachinohe 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: Hachinohe mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aomori Prefecture geography stubs, Extreme points of Japan, Geography of Aomori Prefecture, so understanding it makes those chapters shorter.
In everyday life: Look for Hachinohe 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.
