Underground Mine Portal Entrance - Weeping Water, NE
 
05:55
Omaha, Nebraska is the largest city in Nebraska with a population of over 400,000 people. A growing city the size of Omaha needs crushed stone and gravel to build the roads, sidewalks and foundations on which the people depend. Weeping Water, NE is a small town just 20 miles southwest of Omaha that supplies most of the rock for the Omaha market. Limestone mining operations have been in existence for nearly 100 years in this small town. A normal limestone operation is usually done in an open pit after the overburden has been taken off, but not in Southeast Nebraska. In this part of the country there is over 100' of corn growing dirt on top of the limestone. To add to the problem there is another 110' of non usable rock on top of the Kereford/Platsmouth formation which is the target material for the limestone operation. Due to the massive amounts of overburden and junk rock economics dictate that in order to extract the good limestone it must be removed using underground mining techniques. This underground mining operation uses a room and pillar drill and blast method to extract the rock. Years of mining have left a labyrinth of rooms that spread out from the one and only entrance into the mine. Miles of roads have to be traversed by haul trucks laden with the broken rock to reach the outside world. Engineers were called in to design a way to get to a 20 1/2-foot layer of high quality Kereford/Plattsmouth limestone that is over 200-feet deep. It was decided that the most economical way to reach this layer of rock would be to ramp down to it and remove all the material out of the way. As a safety feature the engineers would put in catch benches. These specially designed benches would keep material from falling from the top all the way to the bottom. By taking a giant triangle out of the ground, haul trucks would be able to drive down the ramp and straight into the Kereford/Plattsmouth limestone layer. Once an acceptable location was selected and the permits issued, construction on the new mine portal entrance began. The future entrance was in the middle of a corn field. Sudbeck Construction performed the site work grading and excavation for the project. First the overburden would be striped off to get to the top of the rock. To construct the mine entrance, 100-feet of dirt overburden had to be removed to get to the top of the rock (1.6 million cubic yards of dirt). The sides were sloped back on a 2:1 to ensure slope stability and the ramp was set on a 10 degree decline. Once the dirt was peeled back it was time for Dykon Blasting Corp. to blast their way down to the Kereford/Plattsmouth limestone layer. The final depth of the excavation was 240-feet from the top of the ground with 140-feet in solid rock. At the surface of the rock the opening is 220-feet wide and 900-feet long. The rock was excavated with 3 separate benches. The ramp followed a constant 10 degree slope down to the bottom where it leveled off for 65-feet before the back wall (Portal entrance). Dykon loaded the blasts with the aid of a bulk explosive truck. The bulk truck blended ANFO (ammonium nitrate fuel oil) and emulsion before auguring the blend into the blast holes. The amount of material that Dykon was able to blast and the time it took to prepare a blast let Dykon stay well ahead of Sudbeck Construction. In one week Dykon blasted enough material to keep Sudbeck digging for a month. During that time Dykon returned home and resumed working on other jobs in Oklahoma and Arkansas. Dykon blasted approximately 500,000 cubic yards of rock which Sudbeck had to load and haul up and out of the hole. The Quarry operator will now take over and begin driving drifts (tunnels) into the Kereford/Plattsmouth limestone. They will also be relocating their primary crusher and screening plant to the new location which is approximately two miles from their existing location. The move should keep the residents of Weeping Water, Nebraska a little happier and a lot less dusty.

Mining Method
 
02:51
Sub level stoping is a commonly used method in large scale mining. It is a versatile and productive method that is primarily used for large orebodies with a steep dip, regular shape and defined ore boundaries. There are different variations of the method depending on the shape of the orebady. However, the method is based on the principale of blasting of large stopes which are usually backfilled to maximiza recovery of the orebody. Drifts are created through the orebody to enable mining of stopes between sublevels. The orebody can be divided into primary and scondary stopes, where the primary stopes are mined first. The scondary stopes are left as pillars until the adjacent primary stopes have been mined and backilled. Stabilized fill in the primary stopes prevent sidewalls to cave in when secondary stopes are mined. opening raises are required to accommondate the initial blast and start up the stoping process. If rock conditios allow, it is common to drill the entire stope before charging and blasting. Once ore from the first section has been blasted and mucked out, enough room is made to blast larger sections of the stope. One of the advantages with blackfilling, is the possibility to reuse waste for blackfill material, such as teilings-sand from the processing plant. The excavation sequence continues according to plan. Before it is time to excavate the secondary stopes, cable blots are often installed above the stope. This will provide additional support to the rock mass, helping to prevent larger blocks from falling into excavated stope. Productivity is maintained at a high rate since it is possible to mine the ore, on different levels and stopes, at the same time. Sublevel stoping is a productive large scale mining method that enables a multitude of production points in operation at the same time, offering good productivity and low dillution.
Minecraft - Most Efficient Mining Strategy to get ALL Ores: Fritz's No Ore Left Behind

No Ore Left Behind Server: mc.cloudcraftfun.net Server Site: http://www.cloudcraftfun.net Texture Pack: Soartex_Fanver Graphics Mod: Optifine Minecraft Version: 1.6.4 This is not the faster way to get diamonds but it is the faster way to be sure you got all diamonds in the mined area. Other strategies may be slightly more efficient to find ores fast. However they always have the small possibility to leave ores behind. This strategy takes slightly more time but ensures you did not leave any Ores. This is especially convenient when mining Emeralds where all other strategies will either take longer or have high risks of missing the Emeralds.

What is STRIPPING RATIO? What does STRIPPING RATIO mean? STRIPPING RATIO meaning- STRIPPING RATIO definition - STRIPPING RATIO explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore. For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock. Stripping ratios are typically reduced to show the volume of waste removal required to extract one unit ton of ore, for example, 1.5:1 as opposed to 3:2. When compared to surface mining, which requires overburden removal prior to ore extraction, underground mining operations tend to have lower stripping ratios due to increased selectivity. All other factors being equal, mining at a higher stripping ratio is less profitable than mining at a lower stripping ratio because more waste must be moved (at a cost per unit volume) for an equivalent volume of revenue generating ore. If the ratio is too high given a particular price of ore and associated cost of mining then it may not be economical to conduct mining.

India’s Stone Quarries are Sounding the Death Knell for Workers
 
04:19
Ramlal Baiga reports from Akbarpur, Uttar Pradesh for Video Volunteers. On the eve of World Tuberculosis Day, it is worth noting that India has the highest occurence rate of the disease in the world, with an estimated 27.9 lakh patients. The government hopes that its strategic plan will eradicate the disease by 2025. It is difficult to tell whether this deadline will be met or not. In the meantime, not a lot is being done to protect and compensate stone quarry workers and mine workers, groups most vulnerable to the tuberculosis (TB). Akbarpur, in Uttar Pradesh’s Bundelkhand, a region known for its stone quarries and crushing units, is a case in point. When Community Correspondent Ramlal Baiga visited Akbarpur, he found that almost every household in Akbarpur has a patient suffering from TB. But what looms larger than the threat of TB in Akbarpur is the threat of silicosis, a disease whose symptoms are very similar to those of TB, but a disease that has no cure. Silicosis is recognised as an occupational disease and a large number of workers, between 3-10 million, are estimated to be vulnerable to the disease. It is caused by the presence of silica in the immediate environment, the inhalation of which affects the lungs. Silica sand is one of the primary minerals found in Chitrakoot, the district Akbarpur falls in.

Mistletoe Mine Underground Exploration: Miniature Rail Trestle, "Twinclines"
 
08:19
I have not found a solid date for the first production from the Mistletoe Mine, but have record of the last production occurring in 1957. This must have been very small-scale production, as we did not find any signs whatsoever of modern mining activity. A Mr. J.D. Torres is listed as the last owner, in 1959. Given the intermittent and frequently very small nature of production in this district, I suspect that production occurred past 1957 on a very small, potential recreational scale. MRDS indicates the presence of a 500ft tunnel, 1300ft tunnel, and several short tunnels as well as raises, stopes, and winzes at this site. Unfortunately, due to impending bad weather (New Mexico can be unpredictable), we were forced to cut our documentation of this mine short and were not able to explore the remaining workings. A small dismantled mill and ore bin exist further down in Mistletoe Gulch, and were connected with these workings via an aerial tramway. Two adits are indicated to exist near the mill. Coming up to the mine, we could see a large spoil pile and timbering that appears to have been the upper station for the tram. Unfortunately, we did not have time to access this portion of the site. What we found is almost certainly one of the upper adits for the Mistletoe group. The presence of multiple ladders hints that we were at the top of a winze or stope, while the (completely intact!) ore car tracks suggest to me that a small stoped-out area exists beyond the winze or stope. I could not figure out if the miniature rail trestle seen in the video was over a false floor or not, and so decided not to proceed. I have no idea what the hell to make of those two openings; Gail has nicknamed them the "Twinclines". My topographic map shows two adits right on top of one another; this leads me to believe that the severe erosion has destroyed evidence of how the openings looked previously. The Mistletoe Mine is located at over 8600ft altitude; both of us were a bit winded from the mile-plus hike up. I have fairly bad acrophobia, so a few segments of the old mine road frankly scared the hell out of me! Another trip to New Mexico is planned for sometime next spring; our first order of business will be thoroughly documenting all workings in Mistletoe Gulch. This area was extensively mined, and seems almost untrafficked. There could be some very interesting finds left in these workings!

How to buy granite: What to look for when buying granite
 
06:57
In this video, Dinesh of Kaladhar Granites in Bangalore explains how to buy granite. You learn how to select the right granite for your needs, how to measure granite and how to calculate the cost of granite slabs. You will learn tips on how to buy granite for your home or office. • How much to buy -- measure the exact size of the room and add 5-10% for wastage. For example, if the room size is 10ft x 10ft - 100 sqft, add 5% for skirting and another 5-10% for wastage. You will need to buy 115 sqft. • How to measure the granite slab -- mark out the maximum square or rectangular measurement on the slab after excluding any defects or breakages around the edges of the slab. Usually, the granite slabs are measured in inches. If the square or rectangle you marked is 90" x 30" then you should pay for 90"x30"=2700 divided by 144 i.e. 18.75 sqft If the measurement is in millimeter, for example 2400mm x 1200 mm, you should pay for 2.4 m x 1.2 m x 10.762 i.e. 2.88x10.762 =30.994 sqft • Buy granite which is water cut - Granite can be cut with water or kerosene as the medium. You should avoid buying kerosene cut granite as it does not stick to cement or glue surface if it is not totally dried. • Don't buy artificially colored granite -- granite can be colored artificially. However, artificial color is not permanent and wears out over time leaving the granite looking like a patch of colors. You can rub the colored surface with some water to see if it is artificially colored. • Granite with fine grains will have more density and will be heavier. • Buy granite with uniform grains -- quality of a granite slab is determined by the uniformity of grains. A slab with uniform surface grains is usually more expensive compared to one with non-uniform grains of veins. However, some people prefer to buy granite with non-uniform grains as it looks unique and is difficult to copy in an artificial stone. • How much to pay for your granite slab -- many things determine the price you pay for granite but come are more important than others. Usually, the price is determined by demand and supply of the specific granite variety. The demand, in turn, depends on suitability of the material for flooring, cladding and other uses. The more versatile the variety, the higher the demand and price. The price also depends on how easily the granite variety fits in with other varieties and material. • Buy a finish that is suitable to the use - granite comes in many finishes. Which one you buy depends on how and where you want to use it. if you are looking to use it as flooring in bathroom or other wet areas, you should buy antiskid finish. You can buy textured finish for heavy traffic areas. Buy polished finish for regular flooring and Kitchen. • How to select the right thickness - granite slabs are generally available in 20 / 30 / 40 mm thickness. You should chose the thickness based on usage. You can also buy 10 mm thick tiles in some cases. Please visit http://www.kaladhargranites.com to find out more and to explore a wide selection of granite for your home and office. Dealers in North America and Europe, contact us for large consignments of high quality granite. Phone: +91 9845043371 / 80 6599 2575 email: [email protected]

These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. De Re Metallica, Georgius Agricola, 1550, Book I, Para. 1Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.

A single pillar granite cutting machine in action at a Stone cutting Industrial operations in Rajasthan, India. A cutting machine prepares slabs of marble and granite at a mine in Rajasthan, India. See the water and marble debris fly out, in slow motion, as this was filmed at 200 frames per second, in Full HD. It is such stone that was sourced for the Taj Mahal in India. India is one among the leading countries in mining and export of granite and is rich in granite reserves. Geologically, the southern and eastern belts of the Nation are abundant in granite deposits. Different shades of granites are available in abundance in Tamil Nadu, Andhra Pradesh, Karnataka, Maharashtra, Assam, Bihar, Rajasthan, Odisha, Meghalaya and Madhya Pradesh. Indian Granite Stone has become the most sought-after and extensively used stone material in building construction and massive structural works throughout the world, and it is well known in the International market, not only for its elegance and aesthetic quality, but also for its durability. The north, especially the state of Rajasthan, is usually associated with marble, sandstone and slates. Few associate the state of Rajasthan with a granite industry. Yet, in an almost furtive manner, unknown to most of the stone industry people, a significant granite industry has been developing in the state in recent years. This relatively recent industry is not just processing materials extracted elsewhere. It is, in fact, extracting granites of a fairly wide range of colours found within the state itself.

Ancient Indian Rock Cutting Technology
 
03:43
Follow Me on: Instagram................ http://instagram.com/praveenET Twitter...................... https://twitter.com/PraveenMohanET Facebook.................https://www.facebook.com/praveenmohanfans Website.................... http://www.phenomenalplace.com Let us take a look at the ancient rock cutting techniques of India, and how they were able to transform rocks into beautiful sculptures. Sometimes, they were also able to convert an entire mountain into beautifully carved temples by doing an extraordinary amount of rock cutting. Even though rock cutting started as early as 200 B.C, the height of rock cutting technology was reached around 600 A.D by Pallavas in South India. Even though there is a lot of evidence of ancient tools that were really advanced, in this video let us stick to the conventional theory of using chisels and hammers. This is the first phase of rock cutting, where they carved a hole that is 1 inch wide and 2 inch deep. After making a hole like this, they would place a wooden wedge and hammer it in. Then, they would pour hot water into it and the wood would start expanding inside the rock. Now, this is not going to crack the rock open, but what happens when you make a series of such holes and place wedges into them? Here you can see how a rock has been completely split into 2 halves and one of them is missing, which means it was transported to a temple and probably made into a beautiful sculpture. We are looking at the other half that was just not used. And this is granite by the way, one of the hardest rocks in the world. You can see how smooth the face of the split rock is. Once the rock has been split like this, they would start the second phase. You can see how they made rectangular pattern on the smooth side of the rock. Measurements would be made, and the rock would be divided into rectangular parts, according to the size of the sculpture that would be created. Once this is done, the unwanted rectangles would be removed by chiseling them away. For example, if all the rectangles except the middle one were chiseled away, the middle rectangle would stand out as a raised platform. The third phase is the careful carving of figures on this raised platform. This is the most important part as it would need a lot of meticulous work and precise artistic carving. The Pallavas of South India were able to create some amazing reliefs, sculptures and cave architecture. One example is the Kailasa temple of Ellora, where they carved an entire mountain and created a beautiful temple. It is estimated that over 400,000 tons of rock were carved out of this mountain to create this temple. Over ten thousand Pallava sculptors were transported from the south to North India to create this. Another example is the world's second largest relief that was created in Mahabalipuram.

Part1- https://www.youtube.com/watch?v=xMzBE... Part3- https://www.youtube.com/watch?v=qVoDX... Written in 1948, 1984 was George Orwell's chilling prophecy about the future. And while the year 1984 has come and gone, Orwell's narrative is timelier than ever. 1984 presents a startling and haunting vision of the world, so powerful that it is completely convincing from start to finish. No one can deny the power of this novel, its hold on the imaginations of multiple generations of readers, or the resiliency of its admonitions.

Restoration (2003) - Rescuing Heritage buildings in Britain. Dir. Simon Mansfield
 
59:47
Episode Four of the UK television series dedicated to the preservation of rare and unusual buildings around the UK. This episode's candidates, all in the northeast of England, were Ravensworth Castle near Gateshead, Harperley WW2 prison camp near Durham and Wentworth Woodhouse Conservatory with Stainborough Castle folly near Barnsley. Other famous locations covered were Hadrian's Wall, Berwick-on-Tweed, Gormley's Angel of the North statue, Alnwick Castle and Dean Clough Mills, Halifax, with a brief nod to the Episode Three contenders, Banchory Sanatorium near Aberdeen, Kinloch Castle on Rhum, and Burra Croft on Shetland. Griff Rhys Jones presented the series. In this episode, contributions were made by the journalist Kate Adie, historian Michael Wood and gardener Rachel de Thame. This was an Endemol Production for the BBC. The sad postscript to this programme is that many of the buildings featured have yet to be secured. Following massive investments, the Wentworth Estate and (in 2013) its conservatory were eventually rescued but failed to operate profitably, resulting in its closure in 2017. Harperley Camp remains largely unrestored but for a very recent effort to restore the theatre building. Despite an ambitious revival project, Ravensworth remains in a ruinous state and on the English Heritage At Risk Register. Banchory Sanatorium was destroyed by fire in 2016. It has been the smaller and simpler buildings that have fared better; Burra Croft now operates as a small island museum. Kinloch Castle on the isolated Scottish Isle of Rhum was once criticised for its dull external design, yet it may well have been its simplicity that largely preserved its lavish interiors. It continues as a tourist attraction but currently requires significant investment following ownership transfer from Scottish National Heritage to a local Community Trust.

Storm Over Warlock by Andre Norton
 
07:05:23
The Throg task force struck the Terran survey camp a few minutes after dawn, without warning, and with a deadly precision which argued that the aliens had fully reconnoitered and prepared that attack. Eye-searing lances of energy lashed back and forth across the base with methodical accuracy. And a single cowering witness, flattened on a ledge in the heights above, knew that when the last of those yellow-red bolts fell, nothing human would be left alive down there. And so Shann Lantee, most menial of the Terrans attached to the camp on the planet Warlock, was left alone and weaponless in the strange, hostile world, the human prey of the aliens from space and the aliens on the ground alike.

Catacombs of Paris
 
11:22
The Catacombs of Paris or Catacombes de Paris are underground ossuaries in Paris, France. Located south of the former city gate (the "Barrière d’Enfer" at today's Place Denfert-Rochereau), the ossuaries hold the remains of about six million people and fill a renovated section of caverns and tunnels that are the remains of historical stone mines. Opened in the late 18th century, the underground cemetery became a tourist attraction on a small scale from the early 19th century, and has been open to the public on a regular basis from 1874. Following an incident of vandalism, it was closed to the public in September 2009 and reopened on 19 December of the same year. The Catacombs are one of the 14 City of Paris Museums that have been incorporated since January 1, 2013, in the public institution Paris Musées. The official name for the catacombs is l'Ossuaire Municipal. Although this cemetery covers only a small section of underground tunnels comprising "les carrières de Paris" ("the quarries of Paris"), Parisians today often refer to the entire tunnel network as "the catacombs".

These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. De Re Metallica, Georgius Agricola, 1550, Book I, Para. 1Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.

The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and even more so under the Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well-engineered. Large numbers remain in some form across the empire, sometimes complete and still in use. Roman Architecture covers the period from the establishment of the Roman Republic in 509 BC to about the 4th century AD, after which it becomes reclassified as Late Antique or Byzantine architecture. Almost no substantial examples survive from before about 100 BC, and most of the major survivals are from the later empire, after about 100 AD. Roman architectural style continued to influence building in the former empire for many centuries, and the style used in Western Europe beginning about 1000 is called Romanesque architecture to reflect this dependence on basic Roman forms. The Romans only began to achieve significant originality in architecture around the beginning of the Imperial period, after they had combined aspects of their original Etruscan architecture with others taken from Greece, including most elements of the style we now call classical architecture. They moved from trabeated construction mostly based on columns and lintels to one based on massive walls, punctuated by arches, and later domes, both of which greatly developed under the Romans. The classical orders now became largely decorative rather than structural, except in colonnades. Stylistic developments included the Tuscan and Composite orders; the first being a shortened, simplified variant on the Doric order and the Composite being a tall order with the floral decoration of the Corinthian and the scrolls of the Ionic. The period from roughly 40 BC to about 230 AD saw most of the greatest achievements, before the Crisis of the Third Century and later troubles reduced the wealth and organizing power of the central government. The Romans produced massive public buildings and works of civil engineering, and were responsible for significant developments in housing and public hygiene, for example their public and private baths and latrines, under-floor heating in the form of the hypocaust, mica glazing (examples in Ostia Antica), and piped hot and cold water (examples in Pompeii and Ostia).
