TYPES OF MINING - SURFACE LEVEL MINING
 
00:59
The word mining brings up images of people underneath the earth, digging in very difficult conditions, with tunnels and heavy equipment. Here is new for you. Not all mining is done that way.  Surface level mining is almost like skimming the surface. Well you can say that as you are walking and you feel something of value under your feet what would you do?  Would you ignore it and leave it behind and walk away or would you pick it up?  Surface level mining is somewhat like that. The mining done on the coast is not like the sub surface mining. Is not about nibbling into the earth and taking things away it about taking what is being given to you. Responsible miners make sure such mining  is carried out in an environmentally responsible manner.

Surface mining
 
11:24
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed. It is the opposite of underground mining, in which the overlying rock is left in place, and the mineral removed through shafts or tunnels. Surface mining began in the mid-sixteenth century and is practiced throughout the world, although the majority of surface mining occurs in North America. It gained popularity throughout the 20th century, and is now the predominant form of mining in coal beds such as those in Appalachia and America's Midwest. This video is targeted to blind users.

This is the largest hard rock royalty generator in the United States, annually contributing $10 million in revenue to American taxpayers through the U.S. Treasury. Did you know that nearly all federal minerals are within the jurisdiction of the Bureau of Land Management? The agency manages more surface land (245 million acres or 10 percent of America’s land base) and more subsurface mineral estate (700 million acres) than any other government agency in the United States. Mineral development is an important land use for communities across the country. Mining provides jobs, economic activity and important commodities that help sustain our growing nation.

The 33 - Official Trailer [HD]
 
02:33
The 33 - in theaters November 13th. http://the33movie.com https://www.facebook.com/the33movie --- From Alcon Entertainment and Phoenix Pictures comes the unforgettable true story of “The 33.” In 2010, the eyes of the world turned to Chile, where 33 miners had been buried alive by the catastrophic explosion and collapse of a 100-year-old gold and copper mine. Over the next 69 days, an international team worked night and day in a desperate attempt to rescue the trapped men as their families and friends, as well as millions of people globally, waited and watched anxiously for any sign of hope. But 200 stories beneath the surface, in the suffocating heat and with tensions rising, provisions—and time—were quickly running out. A story of resilience, personal transformation and triumph of the human spirit, the film takes us to the Earth’s darkest depths, revealing the psyches of the men trapped in the mine, and depicting the courage of both the miners and their families who refused to give up. Based on the gripping true story of survival—and filmed with the cooperation of the miners, their families and their rescuers—“The 33” reveals the never-before-seen actual events that unfolded, above and below ground, which became nothing less than a worldwide phenomenon. The international cast is led by Antonio Banderas, Rodrigo Santoro, Academy Award winner Juliette Binoche (“The English Patient”), James Brolin, and Lou Diamond Phillips, with Bob Gunton and Gabriel Byrne. The main cast also includes Mario Casas, Jacob Vargas, Juan Pablo Raba, Oscar Nuñez, Tenoch Huerta, Marco Treviño, Adriana Barraza, Kate Del Castillo, Cote de Pablo, Elizabeth De Razzo, Naomi Scott, Gustavo Angarita, and Alejandro Goic. Patricia Riggen directed “The 33” from a screenplay by Mikko Alanne, Oscar nominee Craig Borten (“Dallas Buyers Club”) and Michael Thomas, based on the screen story by Jose Rivera and the book Deep Down Dark by Hector Tobar. The film was produced by Oscar nominee Mike Medavoy (“Black Swan”), Robert Katz and Edward McGurn. Carlos Eugenio Lavin, Leopoldo Enriquez, Alan Zhang and José Luis Escolar served as executive producers. The behind-the-scene creative team included cinematographer Checco Varese, production designer Marco Niro, editor Michael Tronick and Oscar-nominated costume designer Paco Delgado (“Les Misérables”). The Academy Award-winning team of Alex Henning and Ben Grossman (“Hugo”) supervised the visual effects. The score was composed by Oscar winner James Horner (“Titanic”). “The 33” was filmed on location in Chile’s harshly remote yet stunningly beautiful Atacama desert just kilometers away from where the event took place, and deep within two mines located in central Colombia. A presentation of Alcon Entertainment and Phoenix Pictures, “The 33” is slated to open on November 13, 2015 and will be distributed by Warner Bros. Pictures, a Warner Bros. Entertainment Company.

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.

State Police Interrupt a Gold Mining Operation in Oregon!
 
15:39
Our mining claim neighbors called the Cops! People living on the other side of the river where our mining claim is and not liking our mining, called the cops. It appears our neighbors just did not want their liberal utopia disturbed so they call the cops to harass us. The police were very cool as I knew one of them from checking our permits on another river couple months earlier and an Oregon DEQ meeting he showed up at. The rude lady yells to at from other side of river "you need a permit to do that"...we had them of course. She also told cops we were disrespecful and rude to her...which was totally false. She made up her own narrative about what was happening to justify her being annoyed. Liberal tactic # 3, change the narrative or just plain lie! This is the short version of the video, filmed on the Applegate River in Oregon while we were LEGALLY GOLD MINING! In the video, it is a continuous video, shot on my GoPro camera that I was wearing on my head. The video shows me mining and moving around with no editing to show what actually goes on while mining. Then my buddy is helping me move rocks while I'm using a sub-surface dredge...then the cops show up , and I tell him is where the action starts. UPDATE Jan 1st, 2015: In response to some of the comments saying we are uneducated, rednecks and other stuff...the guys in the video are as follows. One is a millionaire CPA, another a self employed business owner, two others are also self employed and owns a body shop and the other an internet marketer and freelance videographer, and lastly one is the son of the CPA guy and currently in college. Oregon Mining Law: Next time this happens, I will ask the State Police to cite the offending people who disrupt our mining operation based on this Oregon Mining Law: "ORS 517.133 Interfering with a mining operation. (1) As used in this section, "lawful mining operation" means any small scale mining operation that is in full compliance with state and federal laws. (2) A person commits the crime of interfering with a mining operation if the person intentionally: (a) Interferes with a lawful mining operation; or (b) Stops, or causes to be stopped, a lawful mining operation. (3) Interfering with a mining operation is a Class C misdemeanor. [1999 c.354 §6]" Here is the GoPro camera I was using: http://amzn.to/19yYus6

3:26 for the good stuff What to look for when core mining. 1.) It'll be the brightest asteroid on your screen. 2.) Surface and Subsurface samples glow around their area. An asteroid with a core glows evenly from all angles. If you see dim or unlit spots, move on. 3.) All core asteroids seem to be the same shape depending on ring type. Once you've seen a few for the ring type you're in you'll know what to look for. 4.) Asteroids with a core will have visible fissures on the surface. If it seems to pass the first 3 steps, do a close flyby to save time and limpets. 3:26 for the good stuff

Global Civil & Mining HD Berry
 
01:53
Global Surface Mining (GSM) were contracted to assist with the excavation of rock on a number of significant cuttings along the Princes Highway Bypass near Berry. The rock along the alignment was very consistent and hard. Initially the client had drilled and blasted in some areas and employed rock breakers elsewhere. The blasting caused damage to the rock in the walls and rock breaking was very slow and expensive. Without a change there was a risk to the Project’s program. Furthermore excavations were being carried out alongside the very busy Princes Highway and close to some nearby housing. The 2500SM, which is fitted with GPS level and position controls, cut the walls with great precision and with no damage to the remaining rock in the walls. The result was the creation of walls that were structurally very competent. It was also used to accurately box out the highway in preparation for the placement sub-base material
Strip mining equipment near Canton, IL, July, 1990
 
04:13
When I uploaded this video to YouTube, I wasn't exactly sure where I shot this video on July 4, 1990 of derelict stripping shovels, a drag line and a bucket wheel excavator at a closed coal strip mine. However, Bob Cebuhar commented here that this was the Freeman United Coal Buckheart Mine south of Canton, IL. Much of what's seen here in terms of earth moving or coal mining equipment is enormous. Unfortunately, there isn't anything like a car or truck next to these machines to lend an idea of scale. But, if you look at some of the catwalks and doors on these behemoths, that should give you an idea of how truly massive some of this excavating equipment was. I believe today all this has since been scraped and the mine land reclaimed.

Bauxite mining in Guinea, Boké,  a major mining town,  Boké Prefecture
 
01:01
Boké is the capital city of Boké Prefecture within the Boké Region of Lower Guinea near the border with Guinea-Bissau. It is also a sub-prefecture of Guinea. Located along the Rio Nuñez which flows to its not-too-distant mouth on the Atlantic Ocean, Boké is a port. It is known for the Fortin de Boké museum, formerly a slave fort. The town is served by Boké Baralande Airport. As of 2014 the city and surrounding sub prefecture had a population of 61,449 people.[1]Riots have paralysed a major mining town in Guinea, with protesters destroying property, vehicles and equipment. People in Boke, north-west Guinea, say they can no longer tolerate power cuts and high levels of pollution. Operations at the bauxite mines have been disrupted and several rioters arrested. in Guinea says demosntrators tried to kidnap a senior general sent to help resolve the crisis. Bauxite, an aluminium ore, is the world's main source of aluminium. It consists mostly of the minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).[1][2] In 1821 the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France.[3] In 1861, French chemist Henri Sainte-Claire Deville named the mineral "bauxite".[4] About a third of the world's bauxite reserves are in Guinea, but poverty remains high. Much of the world's aluminium comes from bauxite.Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010, approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis. Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory. Usually, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (the Bayer process). The aluminium compounds in the bauxite may be present as gibbsite(Al(OH)3), boehmite(AlOOH) or diaspore(AlOOH); the different forms of the aluminium component will dictate the extraction conditions. The undissolved waste, bauxite tailings, after the aluminium compounds are extracted contains iron oxides, silica, calcia, titania and some un-reacted alumina. After separation of the residue by filtering, pure gibbsite is precipitated when the liquid is cooled, and then seeded with fine-grained aluminium hydroxide. The gibbsite is usually converted into aluminium oxide, Al2O3, by heating in rotary kilns or fluid flash calciners to a temperature in excess of 1000oC. This aluminium oxide is dissolved at a temperature of about 960 °C (1,760 °F) in molten cryolite. Next, this molten substance can yield metallic aluminium by passing an electric current through it in the process of electrolysis, which is called the Hall–Héroult process, named after its American and French discoverers. Prior to the invention of this process in 1886, elemental aluminium was made by heating ore along with elemental sodium or potassium in a vacuum. The method was complicated and consumed materials that were themselves expensive at that time. This made early elemental aluminium more expensive than gold.[9] See also[edit]

Great Animation Shows How Deep Humans Dug Into The Earth
 
02:54
Courtesy of Tech Insider --- Extreme Journey to the center of the Earth - Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments, crust, and upper mantle. In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere, mostly microbial life, preserved in drilled samples. Most of the technology used for drilling come from advances in the oil and gas industry. Scientific drilling is carried out on land by the International Continental Scientific Drilling Program (ICDP) and at sea by the Integrated Ocean Drilling Program (IODP). Scientific drilling on the continents includes drilling down into solid ground as well as drilling from small boats on lakes. Sampling thick glaciers and ice sheets to obtain ice cores is related but will not be described further here. Like probes sent into outer space, scientific drilling is a technology used to obtain samples from places that people cannot reach. Human beings have descended as deep as 2,080 m (6,822 ft) in Voronya Cave, the world's deepest known cave, located in the Caucasus mountains of the country of Georgia. Gold miners in South Africa regularly go deeper than 3,400 m, but no human has ever descended to greater depths than this below the Earth's solid surface. As depth increases into the Earth, temperature and pressure rise. Temperatures in the crust increase about 15°C per kilometer, making it impossible for humans to exist at depths greater than several kilometers, even if it was somehow possible to keep shafts open in spite of the tremendous pressure. Scientific drilling is interdisciplinary and international in scope. Individual scientists cannot generally undertake scientific drilling projects alone. Teamwork between scientists, engineers, and administrators is often required for success in planning and in carrying out a drilling project, analyzing the samples, and interpreting and publishing the results in scientific journals. Humans have reached the moon and are planning to return samples from Mars, but when it comes to exploring the land deep beneath our feet, we have only scratched the surface of our planet. This may be about to change with a $1 billion mission to drill 6 km (3.7 miles) beneath the seafloor to reach the Earth's mantle -- a 3000 km-thick layer of slowly deforming rock between the crust and the core which makes up the majority of our planet -- and bring back the first ever fresh samples. It could help answer some of our biggest questions about the origins and evolution of Earth itself, with almost all of the sea floor and continents that make up the Earth´s surface originating from the mantle. Geologists involved in the project are already comparing it to the Apollo Moon missions in terms of the value of the samples it could yield. However, in order to reach those samples, the team of international scientists must first find a way to grind their way through ultra-hard rocks with 10 km-long (6.2 miles) drill pipes -- a technical challenge that one of the project co-leaders Damon Teagle, from the UK's University of Southampton calls, "the most challenging endeavor in the history of Earth science." 'A ship flying in space:' Earth seen through the eyes of an astronaut Their task will be all the more difficult for being conducted out in the middle of the ocean. It is here that the Earth´s crust is at its thinnest at around 6 km compared to as much as 60 km (37.3 miles) on land. Drilling all the way to the mantle would also give geologists a look at what they call the Mohorovičić discontinuity, or Moho, for short. Above this mysterious zone, named for the Croatian seismologist who discovered it in 1909, seismic waves travel at around 4.3 miles per second, a rate consistent with those waves traveling through basalt, or cooled lava. Below the Moho, the waves rip along at around 5 miles per second, similar to the rate they travel through a silica-poor type of igneous rock called peridotite. The Moho typically lies between 3 to 6 miles below the ocean floor and anywhere between 12 to 56 miles beneath the continents. This zone has long been considered the crust-mantle boundary, where material gradually cools and sticks to the overlying crust. But some lab studies suggest it’s possible that the Moho represents the zone where water seeping down from the overlying crust reacts with mantle peridotites to create a type of mineral called serpentine. This possibility is exciting, Dick and MacLeod suggest. The geochemical reactions that generate serpentine also produce hydrogen, which can then react with seawater to produce methane, a source of energy for some types of bacteria. Or, the researchers note, the Moho could be something else entirely unknown to science.

What is STRIP MINING? What does STRIP MINING mean? STRIP MINING meaning - STRIP MINING definition - STRIP MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. "Strip mining" is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden). It is most commonly used to mine coal and lignite (brown coal). Strip mining is only practical when the ore body to be excavated is relatively near the surface. This type of mining uses some of the largest machines on earth, including bucket-wheel excavators which can move as much as 12,000 cubic meters of earth per hour. There are two forms of strip mining. The more common method is "area stripping", which is used on fairly flat terrain, to extract deposits over a large area. As each long strip is excavated, the overburden is placed in the excavation produced by the previous strip. "Contour stripping" involves removing the overburden above the mineral seam near the outcrop in hilly terrain, where the mineral outcrop usually follows the contour of the land. Contour stripping is often followed by auger mining into the hillside, to remove more of the mineral. This method commonly leaves behind terraces in mountainsides.

Ventilation Control of Coal Dust in Mines 1980 MSHA
 
03:07
This 1980 MSHA film clip demonstrates various ventilation techniques to control dust including the use of proper face ventilation to effectively remove airborne dust. Over the years, some consensus has emerged on the best dust control practices. The NIOSH Publication, Handbook for Dust Control in Mining summarizes those practices and is available at http://www.cdc.gov/niosh/mining/pubs/pubreference/outputid20.htm . This handbook describes effective methods for the control of mineral dusts in mines and tunnels for different kinds of mines and mining equipment. This includes underground coal and hard-rock mines, as well as surface mines, stone mines, and hard-rock tunnels. Dust control methods described are practical and cost-effective for most mine operators. This is clipped from the 1980 Mine Safety and Health Administration (MSHA) film, Coal Dust: Hazards and Controls.

Elite Dangerous Mining Guide Reboot and Restart Link: https://youtu.be/gxeZ5rPpR5s Now it is the latest gold rush in Elite Dangerous - lot of new equipment and a lot of confusion on how to use it - lets pick-axe through it in Reboot and restart. Using new exploration mechanics, miners can investigate rings to locate the best spots to start their mining sessions, and then the best specific asteroids to probe and excavate for rewards. With the right amount of skill and expertise, the new Abrasion blaster, Sub-surface displacement missile, and Seismic charge launcher will provide some exciting and explosive results. The information below is a short summary of all the new tools that Elite Dangerous miners can equip themselves with for hunting down those motherlodes! Detailed Surface Scanner – Aside from mapping the surfaces of planets, the Detailed Surface Scanner can also be used to identify mineral hotspots within planetary rings. Commanders can fire probes into the rings, which will then clearly display the areas worth investigating on your screen. Pulse Wave Analyser – Upon arrival within a ring, firing this module will send out a pulse of energy that will highlight any asteroids that have lucrative deposits on them. Prospecting Limpet – In the new Analysis Mode, if a Commander fires a Prospecting Limpet at an asteroid, you will be able to see the highlighted location of all the deposits on it, making it easy for you to target and exploit those specific areas. Mining Laser – The standard mining laser will maintain its functionality on all asteroids. If Commanders enjoy mining as it currently is, they can continue doing so. Abrasion Blaster – A new hardpoint module with which Commanders can shoot at Surface Deposits, breaking them off for collection. Whether you do it manually, using the cargo scoop, or with limpets, you’ll be able to collect the resources at your leisure. Sub-surface Displacement Missile – This new hardpoint module is used for harvesting Sub-surface Deposits. The cockpit interface will then show the displacement missile travelling through the rock. Holding down the trigger and releasing at the optimal time displayed by the interface will allow you to recover valuable sub-surface minerals. Seismic Charge Warheads – Certain asteroids, as identified by the fissures discovered on their surface, can be completely broken apart to reveal a treasure trove of resources. Commanders will place Seismic Charges within the fissures at a particular charge level.

Gold prospecting in Arizona Desert ..still lots left
 
02:26
Good gold in the Arizona desert .. Love prospecting for gold out here with the keen 140 Prospecting for placer gold is normally done with a gold pan or similar instrument to wash free gold particles from loose surface sediment.[1] The use of gold pans is centuries old, but is still common among prospectors and miners with little financial backing. Deeper placer deposits may be sampled by trenching or drilling.[2] Geophysical methods such as seismic, gravity or magnetics may be used to locate buried river channels that are likely locations for placer gold.[3] Sampling and assaying a placer gold deposit to determine its economic viability is subject to many pitfalls.[4] Once placer gold is discovered, the gold pan is usually replaced by sluices or mechanical devices to wash greater volumes of material. Discovery of placer gold has often resulted in discovery of hardrock gold deposits when the placers are traced to their source Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Drilling is often used to explore the subsurface. Surface geophysical methods may be used to locate geophysical anomalies associated with gold deposits. Samples of rocks or soil may be collected for geochemical laboratory assay, to determine metal content or detect geochemical anomalies.[5] Hardrock gold particles may be too small to see, even with a microscope. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in third-world countries. A recent study by Australian scientists found that termites have been found to excrete trace deposits of gold. According to the CSIRO, the termites burrow beneath eroded subterranean material which typically masks human attempts to find gold, and ingest and bring the new deposits to the surface. They believe that studying termite nests may lead to less invasive methods of finding gold deposits.[6] where to find gold, how to find gold, minerals, mineral identification, gold mine, gold, the mine, mining gold, how do i find gold, rocks and minerals gold bug 2 mine lab garret how to pan for gold gold bug 2 arizona gold prospecting little san domingo wash linx lake Arizona desert Gold mining in Alaska Gold in California Gold nugget Gold panning Gold Prospectors Association of America Gold rush Hushing Mineral exploration Placer mining Recreational gold mining little san domingo wash lynx lake GPAA
