Kalinin coal mine

Kalinin coal 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 Kalinin coal mine rather than just read about it. In short: The M. I.

Key takeaways

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

Reference excerpt

The M. I. Kalinin coal mine (Ukrainian: Шахта імені М. І. Калініна) is a large coal mine located in the south-east of Ukraine in Donetsk Oblast. It is situated in the city of Donetsk in its Kalininskyi District. The mine forms part of the state enterprise Donetska Vuhilna Enerhetychna Kompaniya (also called Donetsk Coal Energy Company, abbreviated DVEK). The primary coal product extracted is grade OS coal. Kalinin represents one of the largest coal reserves in Ukraine having estimated reserves of 14.9 million tonnes. The annual coal production is around 427,000 tonnes.

History The mine was constructed and designed by Dongiproshakht, and commenced operations in 1961 with a designed capacity of 1.2 million tonnes of coal per year. After the collapse of the Soviet Union, the mine came under the jurisdiction of Ukraine. By 2005, the actual annual production amounted to approximately 352,500 tonnes.

Worked examples

Example 1 — a first encounter with Kalinin coal mine

Start with the simplest possible case. Write down what Kalinin coal 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 Kalinin coal 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 Kalinin coal 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 Kalinin coal mine

In research: Kalinin coal 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 Kalinin coal 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: Kalinin coal mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 establishments in Ukraine, Coal mines in Ukraine, Coal mines in the Soviet Union, so understanding it makes those chapters shorter.
In everyday life: Look for Kalinin coal 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.
