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 is Mexico's number one state exporter of silver?

The northern state of Sonora (capital: Hermosillo) qualifies as such. It provides 29.6% of Mexico's silver production.

Safety in mining?

Mining ventilation is a significant safety concern for many miners. Poor ventilation inside sub-surface mines causes exposure to harmful gases, heat, and dust, which can cause illness, injury, and death. The concentration of methane and other airborne contaminants underground can generally be controlled by dilution (ventilation), capture before entering the host air stream (methane drainage), or isolation (seals and stoppings). Rock dusts, including coal dust and silicon dust, can cause long-term lung problems including silicosis,asbestosis, and pneumoconiosis (also known as miners lung or black lung disease). A ventilation system is set up to force a stream of air through the working areas of the mine. The air circulation necessary for effective ventilation of a mine is generated by one or more large mine fans, usually located above ground. Air flows in one direction only, making circuits through the mine such that each main work area constantly receives a supply of fresh air. Watering down in coal mines also helps to keep dust levels down: by spraying the machine with water and filtering the dust-laden water with a scrubber fan, miners can successfully trap the dust. Gases in mines can poison the workers or displace the oxygen in the mine, causingasphyxiation. For this reason, the U.S. Mine Safety and Health Administration requires that groups of miners in the United States carry gas detection equipment that can detect common gases, such as CO, O2, H2S, CH4, as well as calculate % Lower Explosive Limit. Regulation requires that all production stop if there is a concentration of 1.4% of flammable gas present. Additionally, further regulation is being requested for more gas detection as newer technology such as nanotechnology is introduced. Ignited methane gas is a common source of explosions in coal mines, which in turn can initiate more extensive coal dustexplosions. For this reason, rock dusts such as limestone dust are spread throughout coal mines to diminish the chances of coal dust explosions as well as to limit the extent of potential explosions, in a process known as rock dusting. Coal dust explosions can also begin independently of methane gas explosions. Frictional heat and sparks generated by mining equipment can ignite both methane gas and coal dust. For this reason, water is often used to cool rock-cutting sites. Miners utilize equipment strong enough to break through extremely hard layers of the Earth's crust. This equipment, combined with the closed work space in which underground miners work, can cause hearing loss. For example, a roof bolter (commonly used by mine roof bolter operators) can reach sound power levels of up to 115 dB. Combined with thereverberant effects of underground mines, a miner without proper hearing protection is at a high risk for hearing loss. By age 50, nearly 90% of U.S. coal miners have some hearing loss, compared to only 10% among workers not exposed to loud noises. Roof bolters are among the loudest machines, but auger miners, bulldozers, continuous mining machines, front end loaders, and shuttle cars and trucks are also among those machines most responsible for excessive noise in mine work. Since mining entails removing dirt and rock from its natural location, thereby creating large empty pits, rooms, and tunnels, cave-ins as well as ground and rock falls are a major concern within mines. Modern techniques for timbering and bracing walls and ceilings within sub-surface mines have reduced the number of fatalities due to cave-ins, but ground falls continue to represent up to 50% of mining fatalities. Even in cases where mine collapses are not instantly fatal, they can trap mine workers deep underground. Cases such as these often lead to high-profile rescue efforts, such as when 33 Chilean minerswere trapped deep underground for 69 days in 2010. High temperatures and humidity may result in heat-related illnesses, including heat stroke, which can be fatal. The presence of heavy equipment in confined spaces also poses a risk to miners. To improve the safety of mine workers, modern mines use automation and remote operation including, for example, such equipment as automated loaders and remotely operatedrockbreakers. However, despite modern improvements to safety practices, mining remains a dangerous occupation throughout the world.

Why do miners go to antarctica to mine?

They haven't yet, at least not for any large-scale mining.

As to why - well, it's the usual cause - to make money from whatever they can find in the ground there.

What are advantages and disadvantages of mouse?

Advantages:

  • Small enough to not be noticed around the house and fit in small holes.
  • Big sharp teeth to chop through hard things e.g. Wood, rope.
  • Tiny amounts of food could fill it up.

Disadvantages:

  • However,... small enough to be trampled on.
  • Big parts of it's body i.e. Ears, Tail. Flap about allot.
  • Because, mice live in walls, deadly materials like aespestos (and others) could kill them.

What are benefits and problems of mining in the Amazon Rainforest?

why is it importants for the humans

Group these as goods or services (include regulates

the composition of the atmosphere, maintains soil health and influences the hydrological cycle)

  • At least 3000 fruits are found in the rainforests; of these only 200 are now in use in the Western World. The Indians of the rainforest use over 2,000.
  • The Amazon Rainforest has been described as the "Lungs of our Planet" because it provides the essential environmental world service of continuously recycling carbon dioxide into oxygen.

Does vermiculite contain asbestos?

Some vermiculite deposits contain asbestos, and some products were made with contaminated vermiculite until about the early 1990s. Now vermiculite mines and all manufacturers, world-wide, are prohibited from selling any product that contains asbestos. Vermiculite and asbestos are two different minerals, but at least two major mines in the USA held mixed deposits which contained both.

What kind of mines are there in Ontario?

All kinds of mines are to be found in Ontario, from small family operations producing gem amethyst in the Thunder Bay region, to immense operations producing copper, gold and diamonds, to enormous open pit mines producing limestone, granite, marble, and many other useful rocks. Mining is one of the industrial backbones of the province, and has provided good jobs and enormous tax revenues for over a century.

What would be the punishment for a private party that is mining in Antarctica for non-commercial reasons?

Depending on where the private party chose to establish its mining operation, the first challenge would be moving the equipment onto the continent. Next, equipment doesn't operate predictably on Antarctica, because of the extreme cold.

Another challenge will be operation of the mine, which must include people. Outfitting people and establishing living quarters for workers is expensive and challenging.

Not withstanding the near guarantee of failure for any such venture, countries with claims on the territory so violated may impose fines and jail times on perpetrators. Workers' citizenship could also bring fines and jail times to them for this project.

The task, on its face, is essentially nonsensical.

Whats the largest oil natural gas mining steel production and tourism in Mexico?

According to the latest economic census (2013):

- Mining, excluding oil and gas: USD 54.6 billion (4.5% of Mexico's GDP)

- Oil extraction: USD 37.8 billion (3.1%)

- Tourism: 25.8 billion (2.1)

- Natural gas (includes distribution): 19.5 billion (1.6%)

- Steel production: 11.5 billion (0.9%)

- Petrochemicals: 9.7 billion (0.8%)

Of course, these pale against other economic activities, such as real estate (139 billion, or 11.4% of Mexico's GDP) or retail (190 billion, or 15.6% of GDP).

What is a mining claim?

It is a claim for the mineral rights on a price of property, regardless of who owns the rest of the rights. Sometimes the mineral rights are the most valuable rights and in other cases they are worthless.
