THEY FORGOT THESE GOLD MINES!
 
11:14
Abandoned Mines Mining has been around for ages. Like, the oldest mine is said to be around 43,000 years old! Mining is the process of digging into the earth to find minerals such as coal, gold, diamond or any other mineral that humans find valuable. Since mining has been around for so long and people will dig just about anywhere to find something valuable, it’s not a surprise that many mines become abandoned or forgotten.

Hydraulic Gold Mining in the Old West
 
04:38
Gold in the creeks and rivers was easily found by panning and sluicing, but many of the richest mining areas were in old ancient river channels high above the existing water line. To mine these deposits effectively a different method was required... Hydraulic mining used high pressured water to literally wash away the hillside and release gold. The large hydraulic monitors would break apart the clays and gravel which would be run through a sluice box. Considerable gold was found using this method, and was a major boon to the economy of many of the mining camps throughout the West.

Underground coal mine by Indian minerology
 
09:29
Underground coal mine :- Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production.[5] In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping point (limited by geology, ventilation, or economics), a supplementary version of room and pillar mining, termed second mining or retreat mining, is commonly started. Miners remove the coal in the pillars, thereby recovering as much coal from the coal seam as possible. A work area involved in pillar extraction is called a pillar section. Modern pillar sections use remote-controlled equipment, including large hydraulic mobile roof-supports, which can prevent cave-ins until the miners and their equipment have left a work area. The mobile roof supports are similar to a large dining-room table, but with hydraulic jacks for legs. After the large pillars of coal have been mined away, the mobile roof support's legs shorten and it is withdrawn to a safe area. The mine roof typically collapses once the mobile roof supports leave an area.

How is coal mined? - What is Surface Mining and Underground Mining - Video
 
08:10
How is coal mined? Read Full Story: http://www.spoonfeeding.in/2013/02/how-is-coal-mined-what-is-surface.html Mining is the process of removing coal from the ground. There are two types of mining: underground mining and surface mining. When the coal seam is fewer than 125 feet under the surface, it is mined by surface mining. Coal that is deeper than 125 feet is removed from the ground by underground mining. Underground mining is used when the coal seam lies deep in the earth. In an underground mine only some of the coal is removed. The coal that remains helps support the mine roof. Underground mines look like a system of tunnels. The tunnels are used for traveling throughout the mine, moving coal from place to place and allowing air to circulate in the mine. The coal that is mined is put on conveyor belts. The conveyor belts take the coal to the surface. There are three types of underground mines: slope, drift, and shaft. When the coal seam is close to the surface but too deep to use surface mining, a slope mine can be built. In a slope mine a tunnel slants down from the surface to the coal seam. A drift mine is built when the coal seam lies in the side of a hill or mountain. Drift mines may also be built in a surface mine that has become too deep. There are many drift mines in the eastern United States. The most common type of mine in Illinois is the shaft mine. These mines may be 125 to 1,000 feet deep. A large hole, or shaft, is drilled down into the ground until it reaches the coal seam.

R4bn more will set South Deep up for 50 years -- Gold Fields
 
05:41
JOHANNESBURG (miningweekly.com) -- The planned investment of R4-billion more in the giant South Deep gold project will set the mine up for 50 to 60 years of ongoing operation, Gold Fields CEO Nick Holland says. The fully mechanised 3 500-employee South Deep is the only remaining South African asset of Gold Fields after the hive off of the Kloof, Driefontein and Beatrix gold mines to Sibanye Gold.

Gold Field's mineworkers strike against retrenchments
 
06:56
Mine workers at Gold Field's South Deep mine have embarked on an indefinite strike. The Strike, which started on Friday night, is led by the National Union of Mineworkers -NUM. It follows the company's decision to retrench 1100 of its 5000 workforce due to financial losses. 420 contractors will also be affected. The mine has already issued letters of termination to the workers. But union NUM is having none of it. Our reporter Nozintombi Miya is there for us. For more news, visit: sabcnews.com

How To Find Abandoned Mines
 
31:22
So, you want to know how to find a specific abandoned mine or abandoned mines in general? We will dive into answering that question in this video by taking you along on our search for an abandoned mine that took us two years to locate! Along the way you’ll have the opportunity to observe the tools and techniques we use to find the historic mines that appear in our videos and you will, hopefully, be able to incorporate some of what we have learned over the years (and are now sharing with you) into your own search for mines and mine sites. I will cover how we find out about mines in the first place, the research that we do, the online resources we utilize, the technology we take out in the field with us and more. Whether you are a historian or a gold miner looking for promising sites to file claims on or a mine explorer interested in documenting our industrial heritage or are just curious what is around the area where you live, this video will, hopefully, have something useful for you. Some of you will obviously already know many, if not all, of these search techniques. However, this video is intended to have something for everyone – from the novice to the experienced mine hunter. Many people have no interest at all in finding lost mines, but enjoying seeing them and the efforts of others to find them, and so I have included the footage of the mine when we finally found it for that demographic as well. Fortunately, we don’t normally have to work this hard to find an abandoned mine, but if our search for this mine, although quite unpleasant and frustrating at times, was useful to someone else out there, then it was worth it. Happy hunting! Here are the links for the websites mentioned in this video: https://thediggings.com/ caltopo.com http://www.mylandmatters.org/ http://www.westernmininghistory.com/ https://www.google.com/earth/ https://goldrushexpeditions.com/ ***** All of these videos are uploaded in HD, so adjust those settings to ramp up the quality! It really does make a difference… You can click here for the full playlist of abandoned mines: https://goo.gl/TEKq9L If you like these videos on exploring abandoned mines, please subscribe! https://goo.gl/yjPxH1 Thanks for watching! ***** Growing up in California’s “Gold Rush Country” made it easy to take all of the history around us for granted. However, abandoned mine sites have a lot working against them – nature, vandals, scrappers and various government agencies… The old prospectors and miners that used to roam our lonely mountains and toil away deep underground are disappearing quickly as well. These losses finally caught our attention and we felt compelled to make an effort to document as many of the ghost towns and abandoned mines that we could before that niche of our history is gone forever. But, guess what? We have fun doing it! This is exploring history firsthand – bushwhacking down steep canyons and over rough mountains, figuring out the techniques the miners used and the equipment they worked with, seeing the innovations they came up with, discovering lost mines that no one has been in for a hundred years, wandering through ghost towns where the only sound is the wind... These journeys allow a feeling of connection to a time when the world was a very different place. And I’d love to think that in some small way we are paying tribute to those hardy miners that worked these mines before we were even born. So, yes, in short, we are adit addicts… I hope you’ll join us on these adventures! #ExploringAbandonedMines #MineExploring #AbandonedMines #UndergroundMineExploring

Gold Mining in West Africa
 
01:32
This is a primitive (as well as illegal) gold mining operation deep in the jungle of Liberia, West Africa. The gravel is washed, allowing the alluvial gold dust to be carried by the water through the holes in the head pan and into the carpet (miners moss) on the sluice tray. The gold is recovered by carefully rinsing the carpet.

Gold Mining On The Yuba River
 
09:20
Gold Mining On The Yuba River The Ancient American River, Ancient Yuba River, Ancient Calaveras River, Ancient Mokelumne River, Ancient Tuolumne River, Ancient Magalia Channel, Ancient Intervolcanic Cateract Channel, Ancient Intervolcanic American River and the Ancient Jura River (from the Jurassic Period), are plotted in detail on Big Tens California Gold Map 5. The present-day rivers bearing the same names as their ancient rivers are also shown. The Ancient Rivers of Gold in northern California are from the Tertiary Period. The Tertiary rivers existed millions of years ago and many of them had large quantities of gold within their gravels. Because of that, they are known as the "Ancient Rivers of Gold." Each ancient river is discussed below. Information on this page is based on the classic work of Waldemar Lindgren of the United States Geological Survey and by study of Big Tens California Gold Map 5, which shows the relationship of the ancient rivers to landmarks, such as roads, creeks and towns in the region. These now-dry Tertiary rivers are thought to be a prime source of the gold found in many of the rivers and streams of the Mother Lode region of northern California. The ancient rivers are discontinuous and sometimes follow tortuous routes. They have been altered by volcanic activity, erosion, and in some instances portions of the rivers have been covered by lava. Much of the region underwent extreme volcanic eruptions. Volcanic flows have been found up to 4,000 feet deep. Volcanic flows were up to 60 miles in length. Portions of an ancient river may be found at ground level or near the top of a mountain, or on the side of a mountain, or buried. Early prospectors found portions of the ancient rivers and worked them for their rich gold content. Later, mining companies used hydraulic mining or drift mining techniques to recover the gold. In hydraulic mining, water under pressure is directed to, for example, the side of a ravine to dislodge the gravels and send the material to the sluices where the gold is recovered. The equipment that was used (called a "monitor" or "giant") was similar to a very large hose nozzle. Geologic reports speak of gravel deposits up to 250 feet deep with gold deposits interspersed at various levels within the gravels. Some of the gravels of the ancient rivers of gold have been cemented together over time. Smaller materials between the larger gravels have bound the larger gravels together. Drift mining is used in those instances to follow the channel underneath the volcanic covering. In drift mining, tunnels are driven in bedrock underneath the channels and when the channels are reached, the richest stratum, resting immediately on the bedrock, is extracted by underground mining methods and then washed at the mouth of the tunnel. Many miles of the ancient rivers are still un-worked and may be very rich in gold.
