Abstract We observed very small repeating earthquakes with −5.1 ≤ Mw ≤ −3.6 on a geological fault at 1 km depth in a gold mine in South Africa. Of the 851 acoustic emissions that occurred on the fa...

Abstract. South Africa's gold mines were the first to compensate silicosis and tuberculosis as occupational diseases. They were also the first mines to introduce a state-sanctioned regime of medical surveillance. Despite those innovations, the major mining houses are currently facing class actions by former miners with occupational lung disease

world (in order) are China, US, Australia, South Africa and Russia. In addition to gold that comes from mines, an additional 1,500MT of annual global output on average comes from recycling (World Gold Council 2011). Figure 1: The distribution of gold mine production in Africa …

Abstract The causes of rising demand pull inflation in South Africa are examined with an eye on the international price of gold given the importance of gold mining in the country. Effects of the money supply, exchange rate, foreign income, and an index of political stability are included in

Recent investigations have identified microorganisms in various crustal environments to 2800 meters below the surface (mbls.). Relatively few deep samples of the continued crust (> 800 mbls.) have been collected for microbiological analyses, however, because coring is technically difficult and expensive. The gold mines into the 2.9 Ga Witwatersand Supergroup in South Africa may provide an ...

Abstract . Acid mine drainage is recognized as one of the more serious environmental problems in the mining industry. Acid mine drainage is a major problem on coal and gold mines throughout the world and in South Africa, the main focus of this study, is no exception.

Over 95% of primary gold production in South Africa comes from underground mines. The orebodies in these mines are narrow and further characterized by geological disconti-nuities, preventing the application of mechanization and automation. South Africa hosts the worlds' deepest mines, which reach depths of close to 4 km. The Chamber of Mines ...

Abstract. Aims: To measure the prevalence of silicosis among black migrant contract workers on a South African goldmine and to investigate exposure-response relations with silica dust. Methods: In a cross sectional study, 520 black goldminers (aged >37 years) were interviewed and had chest radiographs taken. Silicosis was defined as International Labour Organisation Classification …

Abstract. The study evaluates the health risk caused by heavy metals to the inhabitants of a gold mining area. In this study, 56 soil samples from five mine tailings and 17 from two mine villages were collected and analyzed for Asernic (As), Lead (Pb), Mercury (Hg), Cadmium (Cd), Chromium (Cr), Cobalt (Co), Nickel (Ni), Copper (Cu) and Zinc (Zn ...

Abstract. Gold mining is a major source of metal and metalloid emissions into the environment. Studies were carried out in Krugersdorp, South Africa, to evaluate the ecological and human health risks associated with exposure to metals and metalloids in …

The Witwatersrand has been subjected to geological exploration, mining activities, parallel industrial development and associated settlement patterns over the past century. The gold mines brought with them not only development, employment and wealth, but also the most devastating war in the history of South Africa, civil unrest, economical inequality, social uprooting, pollution, negative ...

Abstract. Mining takes place at depths of 2-3 km in South Africa, thereby inducing events with M textgreater 3 in the close vicinity of stopes, with the largest events so far recorded being M textgreater 5. As a result, seismogenic processes can be monitored at very short distances with sensors installed ahead of time in seismogenic areas.

Introduction. Africa is on the verge of an unprecedented mining boom. This boom is attracting tens of billions of dollars in foreign investment (Janneh & Ping 2011; Zhang 2011) and will result in substantial economic growth and development, but it also carries big risks for African societies and the environment.Here we highlight potential environmental threats posed by the rapid escalation of ...

ABSTRACT Mining is an activity that many African countries depend on, and Africa's export-oriented mining and quarrying is driven primarily by the commodity hunger of the world's largest economies. In developing countries commodity exports form the most significant portion of exports.

South Africa's Ancient Annunaki Gold Mines. Michael Tellinger has become an international authority on the origins of humankind and the vanished civilizations of southern Africa. Scholars have told us that the first civilization on Earth emerged in a land called Sumer some 6000 years ago. New archaeological and scientific discoveries made by ...

Abstract. Gold mining has been central to the success of South Africa's economy. That labour intensive industry has relied heavily on migrant workers for its profitability. In the past decade, scientists in Johannesburg and Cape Town have identified a pandemic of the serious occupational disease silicosis among gold miners.

Abstract Gold mining in South Africa resulted in vast volumes of tailings, which have been deposited in impoundments. Poor management of most of the tailings dams resulted in the escape of seepage, adversely affecting soils and water quality. Some tailings dams have been partially or completely reclaimed leaving contaminated footprints.

Abstract: Coal mining plays a critical role in the economy of South Africa though posing detrimental environmental effects on aquatic life and the terrestrial environments with one of the major impacts resulting in the deterioration of scarce water resources. From an eco-legal perspective, that is, a legal and environmental assessment approach, the study evaluates the implications of the coal ...
