Rummu quarry

Rummu quarry 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 Rummu quarry rather than just read about it. In short: The Rummu quarry is a submerged limestone quarry located in Rummu, Vasalemma Parish, Estonia, Europe. Much of the natural area of the quarry is under a lake formed by groundwater, and is situated next to a spoil tip.

Key takeaways

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

Reference excerpt

The Rummu quarry is a submerged limestone quarry located in Rummu, Vasalemma Parish, Estonia, Europe. Much of the natural area of the quarry is under a lake formed by groundwater, and is situated next to a spoil tip. The quarry is close to two former prisons, the nearest being the former Rummu prison.

History and geography In the late 1930s, the quarry began to be excavated for open mining of limestone and Vasalemma marble. The latter is a specific kind of limestone with its structure and texture resembling that of marble. During the Soviet era, until the 1990s, excavation was performed as hard labour by Murru and Rummu prisoners, who would excavate and process limestone from the water-drained quarry. When pumping of water ceased, the quarry quickly filled with groundwater, forming a lake, immersing some of the utility buildings and machinery. Next to the lake is the Vasalemma spoil tip (slag heap). Over time, the spoil tip assumed a unique appearance through erosion by water. The Rummu Prison was merged with the Murru Prison in 2001, then in 2004 those were merged with the Harku women's prison. On 31 December 2012, all of these prisons closed permanently. With the closure of the Rummu quarry, the area became a featured location for nature photography, hiking, rafting, scuba diving, as a summer spot, musical and sports events, and as a filming location for its unique layout. The site was depicted in the post-apocalyptic short film The Most Beautiful Day (2015) by Einar Kuusk (et). Several of the deserted buildings at Rummu were featured in the video for hit song "Faded" (2015) by Norwegian DJ Alan Walker and Jesse Kaikuranta's - 'Vielä täällä' also include scenes from Rummy quarry. Since 2015, Architecture students from Estonian Academy of Arts (EKA) have been discussing ideas and drafting several possible sketches and proposals of what the abandoned area of the quarry could become in the future. In 2017, the owners of the property were planning a technology park.

Access and safety The territory is private property, and belongs to KB Auto Eesti OÜ. The place is practically impossible to access by car, since vehicles are prohibited from stopping near the gate of the road to the quarry. Parking around the Keila–Haapsalu road was problematic during Summer periods, as roadsides were filled with parked cars, making purposeful traffic around them difficult. Jump-diving into the lake off derelict buildings is very dangerous, and professional divers have made public recommendations against this practice, because the lake bed contains pieces of thick concrete, tree branches, rebar spikes, metal construction (including machinery), and plenty of barbed wire. In early 2016, the area began to be closed off, because of issues with cars, and because swimming and diving into the lake is dangerous, and the owner has posted relevant warning signs. On 7 August 2014, a 17-year-old girl injured her back when jumping into the water off a derelict building. Then in July 2016, late in the day, a 35-year-old man was found drowned in the quarry.

Worked examples

Example 1 — a first encounter with Rummu quarry

Start with the simplest possible case. Write down what Rummu quarry 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 Rummu quarry 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 Rummu quarry 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 Rummu quarry

In research
Rummu quarry 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 Rummu quarry 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
Rummu quarry is common in secondary-school and first-year university syllabi. It links to neighbouring topics Limestone industry, Lääne-Harju Parish, Mines in Estonia, so understanding it makes those chapters shorter.
In everyday life
Look for Rummu quarry 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.
