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 horses of sable island become used for coal mining?

The Sable Island Ponies were not used for coal mining. The first of these horses are thought to have been survivors of shipwrecks, or that they were sent there for breeding and pasture. Later, the horses that the British seized from the Acadians were purchased and transported there in 1760. The only group of Sable Island Ponies ever taken from the island now live in Shubenacadie Wildlife Park on the mainland of Nova Scotia.

Most ponies that were used for coal mining were Shetland Ponies, which are smaller than the Sable Island Ponies.

You think you might be a sadomasochist what do you do when your parents find out?

You THINK you might be into S & M? Who would know better than you? At any rate, whatever floats your boat, man.... Only you can determine that, though. So, let's say you are into all of that. Fine. I would say as long as you aren't 13 or something, no big deal. If you are very young, I would kind of tap the brakes a bit, and not try to catagorize yourself yet. Wait and see if this is something you feel strongly about, say when you are 21. By then if you are into it, you are pretty much into it. As long as you are not killing anybody, and the acts you engage in are consentual, who can say anything about it? Understand that your parents may not share the same feelings about the situation as you do. And that's OK. They have a right to have an opinion, too. Don't try to convince them to think like you, it won't happen. Tell them that this is who you are. Just as they chose a heterosexual relationship, you have the right to make your own choice. Give them time to adjust, and keep the level of communication open. They will eventually come around to at least respecting your lifestyle. They may never agree with it, but do they really have to? Good luck, Steve.

Does the mining of obsidian affect the environment?

The mining of obsidian can absolutely affect the environment. Any mining in general can strip the Earth of valuable natural resources. Using heavy machinery and processing the ore can be detrimental as well.

How is strip mining harmful?

it produces a lot of dust and ,it destructs the aesthetic and destroys vegetation

How is coral mining done?

Coral mining is where you go deep down into the coral to find special nutrients which are very valuble. Miners rip apart the coral to get deep into the undergrowth and search for nutrients. As they go into the coral, whilst ripping it apart, it is killing the quantity of the coral. Therefore this is a major threat.

What kind of vaginal discharge is most common if you are pregnant?

Clear, odourless discharge and sometimes a creamy type of dishcharge and lots of it is normal during pregnancy. If you have a smelly or particular coloured discharge it maybe the sign of an infection and worth mentioning to your Doctor.

How is oil extracted from tar sands?

OIl Sands (called Tar sands by its detractors) is made up of natural deposits of sand, clay and bitumen ( this is a heavy black viscous oil) and are mined using strip mining in open pit mines or by thermal extraction using steam assisted gravity drainage (SAGD) technology. The two systems are similar except that the liberation of the oil from the sand matrix occurs on the surface with the excavation methods and underground with SAGD.

The oil is purified of all dirt and water and then upgraded on site or at a separate upgrader site. In the case of the distant upgrader, the bitumen is diluted with a conventional light oil to make it flow more easily.They generate oil similar to pumped oil but extracting the oil is more complex. er

Upgrading is done by breaking the oil molecules eith by thermal methods or by catalytic cracking. The broken molecules are still long enough to be classified as oil although some become light petroleum gases. The oil molecules are separated from each other by boilling points into various types of oil and further treated like oil from any conventional source.

What is different deep mining and opencast mining?

rocks and minerals are easy to find and extract when they outcrop on or near the Earth's surface. All that needs to be done id to clear the vegetation and soil from the surface and start digging. Such mining is called open cast mining. deep mining involves sinking a vertical shaft down to the rock layer containing minerals, making a horizontal tunnel following the mineral layer, extracting the minerals by digging done by machines and miners, bringing the loose rock from the mine and piling it up on waste heaps on the surface and transporting the minerals. deep mining is more dangerous than open cast as miners work underground while in open cast workers work on the surface.

Should Hard Rock recognize a liability for site restoration in conjunction with the opening of Lonesome Dove Mine?

The Hard Rock Mining Company has just completed the first year of operations at its new strip mine, the Lone-some Doe. Hard Rock spent $10 million for the land and $20 million in preparing the site for mining operations.The mine is expected to operate for 20 years. Hard Rock is subject to environmental statutes requiring it to re-store the Lonesome Doe mine site on completion of mining operations. Based on its experience and industry data, as well as current technology, Hard Rock forecasts that restoration will cost about $10 million when it is undertaken. Of those costs, about $4 million is for restoring the top soil that was removed in preparing the site for mining operations (prior to opening the mine); the rest is directly proportional to the depth of the mine, which in turn is directly proportional to the amount of ore extracted.

How is strip mining harmful to animals?

Strip Mining can easily destory their natural habitat and even form cave in under the soil ---- Strip mining removes the habitat from many types of animals. During it's operation, a strip mine is not a very animal-friendly place. HOWEVER, after the mine is closed, if the mine owners replace the top soil and other parts of the geologic environment that they displaced, it will soon return to it's normal state and be a perfectly good animal habitat.

Coal mining good or bad?

Its bad because it hurts the environment and causes lung cancer

Describe the iron smelting process of the natural wind powered furnance?

An ancient wind-powered iron smelting technology in Sri Lanka

BEFORE the development of the blast furnace, iron smelting was achieved by ore reduction at temperatures below the melting point of the metal, forming an agglomerated 'bloom' of low-carbon iron and slag. The forced-draught (bellows-operated) shaft furnace known from archaeological studies is usually regarded as the pinnacle of this early smelting technology1--3. Examples of natural-draught furnaces, in which gas buoyancy in a shaft of sufficient height induces a draught adequate to drive the smelting process4, are also known, but are generally regarded as disappointingly inefficient by comparison5. Here I report the discovery and excavation at Samanalawewa, Sri Lanka, of a previously unknown furnace type. The furnaces are all situated on the western margins of hills and ridges, where they are exposed to the strong monsoon winds. Field trials using replica furnaces confirm that this furnace type uses a wind-based air-supply principle that is distinct from either forced or natural draught, and show also that it is capable of producing high-carbon steel. This technology sustained a major industry in this area during the first millennium AD, and may have contributed to South Asia's early pre-eminence in steel production.

What are the social issues with mining metal ores?

Mining metal ores often leads to significant social issues, including displacement of local communities, loss of livelihoods, and conflicts over land use. Environmental degradation from mining activities can contaminate water sources and disrupt agricultural practices, further exacerbating poverty in affected areas. Additionally, labor rights violations, such as poor working conditions and exploitation of workers, are prevalent in many mining operations, particularly in developing countries. These factors can contribute to social unrest and undermine community cohesion.

What is a brownfield environment?

Brownfields are abandoned, idled, or under-used commercial, industrial, and institutional properties where redevelopment and reuse are complicated by light to moderate contamination from hazardous substances and wastes. These properties are most often in urban areas previously used by industrial and commercial operations that generated waste materials.

Is there mining pollution in Asia?

Yes, there is pollution from mining in Asia. There is the "standard" problem with the burning of fossil fuels like gas and diesel to recover ore, and with coal to produce the electricity used in conjunction with mining. The processing of the material leaves a very large pollution footprint, and it's far larger than the mining operations. China in particular has problems. It has burst onto the world metal markets in the last couple of decades, and the Chinese trash their environment to capture an increasingly larger market share.
