Mining in Broken Hill, NSW Australia

Broken Hill is one of the longest-lived Australian mining cities, and home to what may be the world’s largest and richest deposits of silver-zinc-lead ore.

Broken Hill Australia

History

Broken Hill was originally settled by the Wiljakali Aborigines on an intermittent basis, who were said to have called it Wilyu-Wilyu-yong. White settlers’ aggression and diseases eventually drove them away. By 1883 the ore body in Broken Hill had been discovered by Charles Rasp; to mine it, the Broken Hill Proprietary Company was founded in 1885. Now called BHP Billiton, it’s still the largest mining company in the world.

Mining in Broken Hill was done with hand tools and horse drawn carts (even underground) until the 1940s, when diesel powered equipment reduced the amount of labor needed to mine each tonne of ore. Nowadays the influence of mining on Broken Hill is waning due to reduced labor needs and the declining mining industry. Broken Hill now promotes itself as an artistic and tourist destination.

Mining trends 2013

miningMining companies are trying to survive in the volatile environment and harsh economic times. Increase of operational cost and fluctuating commodity prices are among the factors that make operations in the mining industry harder. Moreover, uncertainty in product demand also is a major setback since companies cannot predict how the demand for their product will fair in years to come. Year 2013 will see a variety of trends arise in this sector. They include:

The top mining trends 2013

Uncertainty of commodity demand

Predictions on future demand for products are on the rise. Companies are trying to find ways in which they can remain relevant in the market when their current customers cease to purchase from them. In order to plan the future, companies looking at the past so as to avoid losing in the competition. An example is drawn on the growth of China which has started to slow down is worrying miners who supply to them. This means that the companies will have to find other partners to fill the demand gap.

Mining Techniques Through History

Guest writer Brad Murray: An abundance of journals highlighting many French sailors of the seventeenth and eighteenth century have indicated that coal had been stripped from cliffs among the shores, simply by digging at the bottom with crowbars. And these methods progressed very little until the late eighteenth century.

Mining Techniques Since early civilization, people utilized ceramics, stone, and metals found on the earth’s surface. Most of these findings were utilized for the purposes of creating weaponry, e.g., flint found in France and England designed for making tools and weapons. In addition, flint mines have also been discovered in many chalk areas, in the location where many seams had been seen in galleries and shafts. At the Grimes Graves, the mines are quite well known, and have a Neolithic origin, while additional hard rocks are picked for axes, namely for the Langdale axe industry. It may be interesting to note that the oldest known mine is the “Lion Cave,” whereby radiocarbon dating shows the mine to be almost 43,000 years of age.

Typically, mining falls into two different methods for excavation: sub-surface and surface mining, while the ladder is far more common in the US, the sub-surface method is perfect for removing vegetation on the surface in search of ore deposits. Under the sub-surface method, open-pit mining, quarrying, and strip mining are common methods. Again, surface mining is used much more frequently, and its targets are divided into two basic categories, namely placer deposits and lode deposits. Whether it’s lode or placer, both of which are mined by underground and surface methods.

Much of the machinery utilized in mining consists of drills, bulldozers, as well as explosives, and for placer mining, gravel and alluvium is given to machinery that consists of a hopper or a trommel, which removes minerals from gravel. At which point, the minerals become synthesized for jigs or sluices. In addition, big drills are used for shafts to help collect samples for potential analysis. Many trams can be used to move minors, waste, and materials from one location to the next. For surface mining, large trucks, shovels, and cranes are utilized for those purposes.

History and Chronology of Australian Mining

Australian Mining History

Australian Mining History

Guest writer Brad Murray: Mining in Australia probably started with the arrival of Aborigines some 40,000 years ago when they fossicked for stones suitable for tools and weapons, and dug for ochre which they used for decorative use.

“Modern” Australian mining followed the arrival of European settlers on the eastern seaboard in 1788, with the quarrying and shaping of Hawkesbury sandstone for early buildings at Sydney Cove. The first discovery of coal was made by escaped convicts in the Newcastle area in 1791. Over the next few years coal was reported at many other centres to the north and south of Sydney.

The coal industry began in 1798 when ship owners gathered surface coal at Newcastle and brought it to Sydney for sale. Export of Newcastle coal began in 1799 with a shipment to India.

Traces of metallic minerals, particularly gold, were found in the early part of the 19th century, mainly by shepherds and convicts. However, there was no concerted effort towards mining because an archaic English law demanded that all gold and silver remained the property of the Crown. In fact, Britain did not encourage people in the young colony to explore for minerals. The colony was first and foremost a penal settlement, and most of its inhabitants in the early years were preoccupied with learning how to feed themselves.

Lead was the first metal mined in Australia from the Glen Osmond hills on the outskirts of Adelaide in 1841. This was followed by the commemcement of copper mining at Kapunda in the same general area in 1842. Copper was also discovered at Burra Burra (SA) in 1845.

When many Australians migrated to the United States in 1849 following reports of rich gold discoveries in California, the New South Wales Government realised that if the wave of migration was to be reversed, it needed to provide incentives for Australians to find gold in their own country. Accordingly, rewards were offered for the discovery of “payable” gold.
In April 1851 the first reported discovery of payable gold was made by John Lister and William Tom at the junction of Lewis Ponds and Summer Hill Creeks, Ophir. Edward Hargraves, an associate of Lister and Tom, took their gold to the Colonial Secretary and then claimed the reward which included 5,000 pounds to Hargraves; and 500 pounds each to Lister, Tom and the Rev. W.B. Clarke. However, recently-discovered evidence in letters addressed to William Tipple Smith from the Government acknowledged the existence of gold at Ophir in 1848.

Coal Mining Technology

Germany’s coal mining industry is all but finished as viable coal seams are worked out. Following an earthquake, mines in the Saarland will close in 2012 and mining in North Rhine-Westphalia’s will end in 10 years at most.

But German mining equipment is still in demand; more than a hundred mostly medium-sized businesses have found customers in countries where mining is booming. One such company is Eickhoff, in Bochum, which produces milling and cutting equipment for coal mining. Now Eickhoff exports 95% of its mining equipment, mainly to China and Russia. Robert Donauer went to a mine in the Ruhr Valley and paid a visit to Eickhoff.
