Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

When did the pike river mine disaster happen?
There were four explosions and one fire in total. The first explosion was at 3:44pm 19 November 2010, the second explosion at 2:37 24 November 2010, the third at 3:39 26 November 2010, a fourth significant explosion ignited the coal within the mine; the subsequent fire was visible above the ventilation shaft; the steel structure above the shaft was damaged and neighbouring scrub set alight. The fire appeared to be located near the bottom of the shaft, burning either loose coal or the seam itself.
What country is the leading producer of copper in Australia and Oceania?
Australia. As of 2011, it marks 5th on the World Rank.
Why was the tin mines closed down?
Because we did not use as much tin as we mined so the value of tin dropped and people did not want to work in the conditions
Can you get a disease from mining iron ore?
Yes, people who mine in general are at serious risk to obtain lung disease if the dust levels are above the limit. Though there are more common lung diseases you can get if you inhale to much of the dust such as chronic bronchitis, bronchial asthma, and collagen vascular disease of the lungs.
The hardest thing to differentiate is between asympotomatic sarcoidosis and pneumonia.
Who owns the kalgoorlie super pit?

A pulsation dampener is a device that can reduce or eliminate the
intermittent gaps left in a pressurized system at the time of system's
discharge stroke.Mainly Pulsation dampeners provide us a variety of
applications.pulsation dampener can be used in virtually all pressurized
devices to protect hardware, decrease maintenance costs, decrease down time,
increase performance, and increase efficiency.pulsation dampener also
used in electronic or mechanical devices that work underwater or in
other pressurized environments.Drilling pulsation dampener is one of the main example of pulsation dampener.
Why cant you reclaim an open-pit mine when it is closed?
It can be reclaimed, it just takes lots of fill and a lot of time to landscape it.
It may not be evil, but it is necessary for life beyond the stage of being a caveman. Come to think of it, even the caveman mined rocks to make stone spearheads. Metals and minerals that are used in everyday life come from mining. The computer you are using to read this contains about 30 substances obtained by mining. It is powered by electricity carried on copper wires (mining) from the powerplant, which probably uses coal or uranium (mining) The food you ate tonight was transported in a metal truck (mining) that traveled on a paved road that was made with crushed stone (mining). If someone did not grow a material, it was, at some point, dug out of the ground.
What does miners hat represent?
A miner's hat typically represents resilience, hard work, and the mining profession, symbolizing the labor and challenges faced by miners underground. It often features a light, signifying the importance of visibility and safety in dark environments. Additionally, the hat can evoke themes of community and the economic significance of mining in various regions. Overall, it serves as a powerful emblem of both the industry and the individuals who contribute to it.
What is the method of hydraulic mining?
Spraying high pressure water jets against mountain sides to wash away the mountain and allow valuable metals like gold and platinum to be captured in enormous sluice boxes. The muddy runoff from hydraulic operations kill most fish and other river life and causes silting over of farmland in flat lands that the drainage rivers run through. It is now banned in most places.
What are some of the controversy of mining today?
Mining is one of the main sources of energy for the planet today. We must mine for coal, oil, and natural gas, as they are not available anywhere else than under the ground. Mining also must be used to obtain raw metals such as iron, gold and tin, and raw materials used in fusion, such as uranium.
ADVANTAGES:
- Mining allows us to obtain materials and fuels that otherwise would not be available to us.
- Mining creates jobs for people
- Mining is essential to most economies
- Mining today can be done reasonably cleanly
- Closed mines don't damage the aesthetic environment.
- Mining nowadays is quite efficient and alot less dangerous.
DISADVANTAGES:
- Mining is very polluting to the environment. Large machines are used to drill the wanted product out of the rock/ground.
- Mining is not sustainable, especially with fuel mining. Fuels such as oil are being mined at a much faster rate than is naturally being produced.
- Mining creates conflict between countries and govenrments. Desert countries such as Iran hold the most amounts of oil, which can often lead to larger countries battling each other to claim it.
- Open mines are not aesthetically pleasing. In places such as the Amazon rainforest, they destroy natural habitats.
- If not correctly done, mining can cause very large amouns of waste, and if not dealt with efficiently (many illegal mining companies do this) end up destroying areas and polluting habitats such as seas and freshwater rivers.
- Spillages are often very damaging to the environment. Take the BP oil spill!
Where is virgin gold mining corporation located?
The office is at the Torre Global Bank Bldg. located in Panama
Hydraulic mining, or hydraulicking, is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold.
What is a copper banded dollor worth?
$1. I'm assuming you mean an Eisenhower dollar with a copper band on the reeding? That is because the Eisenhower dollar was struck in copper-nickel and not silver, as such it is only worth $1.
