Panguna Copper Mine
Panguna is a town and a (now decommissioned) copper mine on Bougainville Island, Papua New Guinea. It was owned and operated by Bougainville Copper Ltd, a subsidiary of Rio Tinto. Beginning operations in 1972, the company hired thousands of workers, most from other parts of the country. By the end of its operations on May 15, 1989, when the mine was closed because of an armed uprising on the island, it was the largest open-pit mine in the world. It was accused of contaminating large areas due to its toxic waste, which affected land, water and air. Resentment against the environmental poisoning and the fact that most profits left the island, were major catalysts in the unrest in Bougainville in the 1970s and 1980s, leading to the Bougainville conflict, which lasted from 1988 until 1998. In 2011 it was reported that former PNG Prime Minister Sir Michael Somare had alleged that Rio Tinto played a role in the conflict by helping finance the actions of the PNG government in Bougain ...

Surface Mines In Papua New Guinea
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surface ...

Populated Places In The Autonomous Region Of Bougainville
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations.

Bougainville Revolutionary Army
The Bougainville Revolutionary Army (BRA) was a secessionist group formed in 1988 by Bougainvilleans seeking independence from Papua New Guinea (PNG). The leader of the BRA was Francis Ona who led the BRA against the Papua New Guinea Defence Force during the violent 10 year conflict. Not all BRA members agreed to the Peace Treaty and boycotted it, and have held out in an official no-go zone, protected by members of the Meekamui Defence Force, currently commanded by Moses Pepino. BRA leaders argued that Bougainville is ethnically part of the Solomon Islands and has not profited from the extensive mining that has occurred on the island. In 1989, BRA leaders proclaimed Bougainville independent from PNG and established the Autonomous Bougainville Government (ABG). As a result, fighting between the BRA and the PNG Defence Force, with support from Australia, escalated. In January 1991, the Honiara Declaration [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Bougainville
Bougainville, an autonomous region of Papua New Guinea (PNG), has been inhabited by humans for at least 29,000 years, according to artefacts found in Kilu Cave on Buka Island. The region is named after Bougainville Island, the largest island of the Solomon Islands archipelago, but also contains a number of smaller islands. The first arrivals in Bougainville were ethnically Australo-Melanesian, related to Papuans and Aboriginal Australians. Around 3,000 years ago, Austronesians associated with the Lapita culture also settled on the islands, bringing agriculture and pottery. Present-day Bougainvilleans are descended from a mixture of the two populations, and both Austronesian and non-Austronesian languages are spoken to this day. In 1616, Dutch explorers Willem Schouten and Jacob Le Maire became the first Europeans to sight the islands. The main island was named after French admiral Louis Antoine de Bougainville, who reached it in 1768. The German Empire placed Bougainville under ...

Michael Somare
Sir Michael Thomas Somare (9 April 1936 – 26 February 2021) was a Papua New Guinean politician. Widely called the "father of the nation" (), he was the first Prime Minister after independence. At the time of his death, Somare was also the longest-serving prime minister, having been in office for 17 years over three separate terms: from 1975 to 1980; from 1982 to 1985; and from 2002 to 2011. His political career spanned from 1968 until his retirement in 2017. Besides serving as PM, he was minister of foreign affairs, leader of the opposition and governor of East Sepik Province. He served in a variety of positions. His base was not primarily in political parties but in East Sepik Province, the area that elected him. During his political career he was a member of the House of Assembly and after independence in 1975 the National parliament for the East Sepik Provincial – later open – seat. He was the first chief minister at the end of colonial rule. Thereafter he became the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bougainville Conflict
The Bougainville conflict, also known as the Bougainville Civil War, was a multi-layered armed conflict fought from 1988 to 1998 in the North Solomons Province of Papua New Guinea (PNG) between PNG and the secessionist forces of the Bougainville Revolutionary Army (BRA), and between the BRA and other armed groups on Bougainville. The conflict was described by Bougainvillean President John Momis as the largest conflict in Oceania since the end of World War II in 1945, with an estimated 15,000–20,000 Bougainvilleans dead, although lower estimates place the toll at around 1,000–2,000. Hostilities concluded under the Bougainville Peace Agreement in 1998. The national (PNG) government agreed to the founding of the Autonomous Bougainville Government and to certain rights and authorities which the autonomous government would have over what became known as Bougainville Province, which includes outlying small islands in addition to Bougainville Island itself.

Environmental Effects Of Mining
Environmental effects of mining can occur at local, regional, and global scales through direct and indirect mining practices. The effects can result in erosion, sinkholes, Biodiversity loss, loss of biodiversity, or the Soil contamination, contamination of soil, Groundwater pollution, groundwater, and surface water by the chemicals emitted from mining processes. These Process chemistry, processes also affect the atmosphere from the emissions of carbon which have an effect on the quality of human health and biodiversity. Some mining methods (lithium mining, Phosphate mineral, phosphate mining, coal mining, mountaintop removal mining, and sand mining) may have such significant environmental and public health effects that mining companies in some countries are required to follow strict environmental and rehabilitation codes to ensure that the mined area returns to its original state. Erosion Erosion of exposed hillsides, mine dumps, tailings dams and resultant siltation of draina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mine Closure
Mine closure is the period of time when the ore-extracting activities of a mine have ceased, and final decommissioning and mine reclamation are being completed. It is generally associated with reduced employment levels, which can have a significant negative impact on local economies. It is also the period when the majority of mine reclamation is completed, making the land safe and useful again. In South Africa, which is a major mining country, closure planning has not yet been formalized. This has led to a range of unintended consequences that have the potential to become sovereign risk if not adequately managed. Closure planning, a relative newcomer to mine planning, continues throughout the life of a mine, starting with conceptual closure plans prior to production, periodic updates throughout the life of the mine, and a final decommissioning plan. This is captured more coherently in the Australian Model to mine closure. At most mines, progressive reclamation over the life of the ...

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...
