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.

What does an over-man do in the coal mines?
overman work in underground as an in charge one district of coal pannel
a general conclusion is like an overall outcome. for example: the class' general conclusion was that there should be no homework for a week.
What is the most famous diamond in the world?
I think that would be the Hope Diamond. It's not the biggest or most expensive, but over the years it's had a lot of press.
gold mining is bad because it leaves a scar in the land.
it is also bad because it destroys over 300 trees, which is killing the population as trees breath out oxygen. but with no trees no oxygen!!
What country mines uranium in Europe?
Working mines: Ukraine, Czech Republic, Romania Non-working mines: Germany, France, Sweden, Hungary, Bulgaria
What is positive about Rio Tinto?
As there website homepage declares: "Helping to create and maintain the diversity of natural life is a responsibility that we take very seriously. We operate in regions throughout the world that are recognised and valued, both locally and globally, for their biodiversity and we are committed to managing them by reducing our impacts and capitalising on conservation opportunities. There is now increasing expectation that industry should take a role in conservation management. Our biodiversity programmes enable us to better understand and address identified issues through a sustainable development approach, involving traditional landowners and local communities, governments and local non government organisations (NGOs). Our strategy states that we aim to have a net positive impact (NPI) on biodiversity. We, therefore, need to demonstrate that our actions have positive effects that outweigh the inevitable negative effects of the physical disturbances and changes of land associated with mining. "

What is the history of coal mining?
oal is formed when peat is altered physically and chemically. This process is called "coalification." During coalification, peat undergoes several changes as a result of bacterial decay, compaction, heat and time. Peat deposits are quite varied and contain everything from pristine plant parts (roots, bark, spores, etc.) to decayed plants, decay products and even charcoal if the peat caught fire during accumulation. Peat deposits typically form in a waterlogged environment where plant debris accumulated; peat bogs and peat swamps are examples. In such an environment, the accumulation of plant debris exceeds the rate of bacterial decay of the debris. The bacterial decay rate is reduced because the available oxygen in organic-rich water is completely used up by the decaying process. Anaerobic (without oxygen) decay is much slower than aerobic decay. For the peat to become coal, it must be buried by sediment. Burial compacts the peat and, consequently, much water is squeezed out during the first stages of burial. Continued burial and the addition of heat and time cause the complex hydrocarbon compounds in the peat to break down and alter in a variety of ways. The gaseous alteration products (methane is one) are typically expelled from the deposit, and the deposit becomes more and more carbon-rich as the other elements disperse. The stages of this trend proceed from plant debris through peat, lignite, sub-bituminous coal, bituminous coal, anthracite coal to graphite (a pure carbon mineral). Because of the amount of squeezing and water loss that accompanies the compaction of peat after burial, it is estimated that it took 10 vertical feet of original peat material to produce 1 vertical foot of bituminous coal in eastern and western Kentucky. The peat-to-coal ratio is variable and dependent on the original type of peat the coal came from and the rank of the coal.
What former governor was murdered during a mining dispute?
Former Governor William Goebel of Kentucky was assassinated during a political and mining dispute in 1900. He was shot on January 30, shortly after being inaugurated, amid tensions surrounding a contested election and labor conflicts in the coal industry. Goebel succumbed to his injuries on February 3, making his assassination a notable event in Kentucky's turbulent political history.
What type of scientists study birds?
Ornithologists are scientists who study birds. They observe bird behavior, study bird anatomy and physiology, track migration patterns, and research bird conservation to learn more about these fascinating creatures.
What are some examples of industries?
Industries include what makes the country run. Some examples include oil, zinc, sulfur, fluroine, pashmina, etc.
Should mining companies be forced to pay the cost of reclaiming a mine site?
Yes And In Australia they are, It is interesting to note that generally however these same mining companies do nothing to preserve the ecology unless they are forced to by law.
What is a synonym for conclusion?
decision, opinion, conviction, verdict, judgment, deduction, inference
end, ending, close, finish, completion, finale, termination, bitter end
outcome, result, upshot, consequence, culmination
How much gold does US produce?
US gold production rises and falls with the price of gold. In 2007 the United States produced approximately 240 tonnes of gold, this is substantially higher than historicl production but typical of the production in the recent past..
Can you suction dredge in South Dakota?
Yes you can. I pasted the rule and link below.
1. Do I need a mine permit to operate a dredge in South Dakota?
To operate any type of dredge in South Dakota to extract minerals such as gold, even for recreational purposes, an operator is required to obtain a mining permit. Mine permits are also required for other mechanized equipment such as highbankers and heavy equipment. To find out more about mine permits, click here.
If you use hand held equipment such as a pick, shovel, pan, metal detector, or sluice box for placer mining, no mine permit is required. However, you are required to comply with South Dakota Water Quality Standards.
You should be aware that a water right permit is required for placer mining activities. However, some of the streams in the Black Hills have been fully appropriated. Therefore, obtaining a water rights permit may not be possible. For more information, contact the Water Rights Program.

What is a large pile of rock and debris left by a receding glacier?
A large pile of rock and debris left by a receding glacier is known as a moraine. Moraines can consist of different sizes of material, from clay and silt to boulders, and are typically deposited along the sides or at the terminus of a glacier.
