Greenhouse gasses that are released into the air when mining are harmful to the environment and the release of dust particulates negatively affect the ecosystems around the mines. As well as the air pollution there is usually a large amount of noise. In Gauteng large scale mining has caused the dolomite rock to cave in which has resulted in large sinkholes forming and earthquakes. One of the biggest problems with gold mining in South Africa is the disposal of the overburden from the mines. Another problem is the use and disposal of the cyanide solutions which are used to extract and dissolve the gold.
For one, coal mining is one of the most water intensive industries, often requiring 2.5 tonnes of water for each tonne of coal produced, creating three to six billion tonnes of water waste per year. This can affect the water table by drastically increasing its PH, and it alters groundwater levels tremendously (due to the amount of water needed to refine the coal). Also, mining releases coal burnings into the air that combine with oxygen to form SO2. This SO2 can then mix with the moisture in the air to form acid rain which can harmful to the environment. Of course, coal mining doesn’t just affect the environment around us, it also can be disastrous to the workers in the coal mine.
INTRODUCTION: BHP Billiton is a diversified leading global resources company. BHP is world’s top producers of major commodities, like silver, nickel, copper, oil and gas, iron ore, metallurgical and energy coal, aluminum, manganese, uranium. • The biggest maker on the planet, BHP Billiton Limited has reported a benefit of $ 200 billion business sectors with a business underwriting of more than (ASX BHP) as of late in the six months to December 2013 declared a benefit of $ 7.8 billion. The aggregate net benefit figure of BHP's has incorporated more than $ 140 billion since 1985 (King, 2014). • BHP Billiton kept up a strong position in the nine months at the end of March 2014 with a record of accomplished fulfilled for four things and at 10 operations.
Destructive extraction of gold remains a major source of public health risk worldwide and causes a plethora of environmental complications. The link between the “global gold rush” and the negative impact on humanity are seen in developing countries that are heavily overwhelmed by poverty and weak economies. Mercury is a ubiquitous metal whose origin is either natural or anthropogenic. This potent neurotoxin is released when poverty-driven arsenal miners extract gold in more than 50 countries.1 This dilemma is particularly prevalent in African countries such as Tanzania. It is estimated that more than 100 million people all over the world are exposed to mercury from small-scale mining, both directly and indirectly.
Many miners had to work underground for 10 + hours a day and 6 days a week(Cobb, James "Coal") The number of deaths per year is the equivalent of a Titanic going down in the nation's coal fields each year (Turkington, Carol) According to James Cobb from the World Book Online Reference Center mine safety involves four main types of problems including accidents involving machinery, roof and rib failures, accumulations of gases and concentrations of coal dust. The accidents involving machinery kill and/or hurt more coal miners in a year than any other mining accident. The machinery in mines are located in cramped spaces with little light, causing miners to have two times the chance of accidents. The accidents involving roof and rib failures can usually be averted if a mining company has a roof support plan. For a roof support plan to be made, information like entry widths, mine geometry, the number of pillars that must be left up right, and the number of bolts that must be used are needed (Cobb 3 of 5) Accumulations of gases in underground coal mines is another very serious hazard.
Marcellus Shale drilling causes a problem because it involves the use of hundreds of deadly chemicals. Over three hundred chemicals are used in the Marcellus Shale drilling process (Environmental). According to Howells, author of the article “Don’t Frack with Our Water!,” these chemicals are especially dangerous because the companies that use them will not tell the public what specific chemicals are being used. However, through studies of the chemicals, some of them can be identified. Some of the chemicals in the fracking fluid and wastewater have been identified as carcinogens.
Even after 130 years Rio Tinto is still the second largest mining company in the world, the production of 10 tons of copper, zinc and 7.5 tons of other minerals. S... ... middle of paper ... ...e public stock exchange, then joint forces to start opening other mines in the world. Mines that produced coal, uranium, diamonds, gold, copper and zinc. Throughout the years of its growth Rio Tinto has maintain a good reputation among the authorities and governments. Rio Tinto has not only been a mining company but an investor to small and coming business that would help it to gain a competitive advantage to the mining industry.
Their only goal in life is to drill for the gold dust which seems to collect at the bottoms of waterfalls then use the profits for illegal self indulgences like cocaine. To extract this gold dust they must combine mercury with the dust, and because of the mercury’s chemical make-up it is able to extract the gold from the useless rock and debris. The mercury, however, isn’t the cleanest element for the environment. Many garimpeiros carelessly use the mercury then dump it into the rivers polluting the water and the food. Also, the dust from the mercury gets inhaled and eating by the miners, contributing to their polluted way of life.
According to Mark Tran, writer for The Guardian newspaper, Tanzania has more than 800,000 small-scale gold miners, thousands of whom are children. Most of the small-scale mining takes place on unlicensed, unauthorized mines (Tran). “A child considered malnourished is one whose weight is more than 20 percent below the normal reference weight for his or her age” (Snarr 217). A large number of the children in the world are malnourished. The number of malnutrition children is slowly decreasing but in Africa not much progress has been done.
The mine that collapse had a history of instability that had caused previous accidents, including death. Chile has a long tradition of mining, during the 20th century they made it as the world top producer of copper. According to a review of data collected by the state regulatory agency (Sernageomin data), since the year 2000, it is found out that there is an average of 34 deaths every year due to mining activity in Chile, with a peak of 48 in the year 2008. (Ethiraj, 2010) More to the accident, when the collapse occurred there were two groups of miners. A dust cloud rose during the collapse, causing enduring eye irritation; blinding the miners for six hours.
