How simple reinforcement is used to prevent collapse of rock tunnels. Join Dollar Shave Club for only $5 at http://www.dollarshaveclub.com/PracticalEngineering Tunnels play an important role in our constructed environment as passageways for mines, conveyance for utilities, and routes for transportation. Rock bolts are a type of reinforcement for stabilizing rock excavations, usually made from steel bars or bolts. This simple construction method dramatically reduces the cost of making tunnels through rock safe from collapse.

Oil Drilling | Oil & Gas Animations
 
08:22
- Like our Facebook: https://www.facebook.com/oilvips - Geologists and geophysicists have agreed on the existence of a "prospect", a potential field. In order to find out if hydrocarbons are indeed trapped in the reservoir rock, we must drill to hit them. Bearing in mind the knowledge acquired about the substratum and the topography of the land, the best position for the installation of the drilling equipment is determined. Generally it is vertically above the point of maximum thickness of the geological layer suspected of containing hydrocarbons. The drillers then make a hole in conditions that are sometimes difficult. Of small diameter (from 20 to 50 cm) this hole will generally go down to a depth of between 2000 and 4000 meters. Exceptionally, certain wells exceed 6000 m. One of them has even exceeded 11 000 m! Certain fields can be buried at a depth equivalent to the height of 12 Eiffel Towers ... The derrick is the visible part of the drilling rig. It is a metal tower several tens of meters high. It is used to vertically introduce the drill strings down the hole. These drill strings are made up of metallic tubes screwed end to end. They transmit a rotating movement (rotary drilling) to the drilling tool (the drill bit) and help circulate a liquid called "mud" (because of its appearance) down to the bottom of the well. The drilling rig works like an enormous electric hand-drill of which the derrick would be the body, the drill strings the drive and the drilling tool the drill bit. The most usual tool is an assembly of three cones -- from which comes the name "tri cone" -- in very hard steel, which crushes the rock. Sometimes when the rock being drilled is very resistant, a single- block tool encrusted with diamonds is used. This wears down the rock by abrasion. Through the drill pipes, at the extremity of which the drill bit rotates, a special mud is injected, which the mud engineer prepares and controls. This mud cools the drill bit and consolidates the sides of the borehole. Moreover it avoids a gushing of oil, gas or water from the layer being drilled, by equilibrating the pressure. Finally, the mud cleans the bottom of the well. As it makes its way along the pipes, it carries the rock fragments (cuttings) to the surface. The geologist examines these cuttings to discover the characteristics of the rocks being drilled and to detect eventual shows of hydrocarbons. The cuttings, fragments of rock crushed by the drill bit, are brought back up to the surface by the mud. To obtain information on the characteristics of the rock being drilled, a core sample is taken. The drill bit is replaced by a hollow tool called a core sampler, which extracts a cylindrical sample of several meters of rock. This core supplies data on the nature of the rock, the inclination of the layers, the structure, permeability, porosity, fluid content and the fossils present. After having drilled a few hundred of meters, the explorers and drillers undertake measurements down the hole called loggings, by lowering electronic tools into the well to measure the physical parameters of the rock being drilled. These measures validate, or invalidate, or make more precise the hypotheses put forward earlier about the rocks and the fluids that they contain. The log engineer is responsible for the analysis of the results of the various loggings. The sides of the well are then reinforced by steel tubes screwed end to end. These tubes (called casings) are cemented into the ground. They isolate the various layers encountered. When hydrocarbons are found, and if the pressure is sufficient to allow them come to the surface naturally, the drillers do a flow check. The oil is allowed to come to the surface during several hours or several days through a calibrated hole. The quantity recovered is measured, as are the changes in pressure at the bottom of the well. In this way, a little more knowledge is gained about the probable productivity of the field. If the field seems promising, the exploration team ends the first discovery well and goes on to drill a second, even several others, several hundred or thousand meters further away. In this way, the exploration team is able to refine its knowledge about the characteristics of the field. The decision to stop drilling is made only when all these appraisal wells have provided sufficient information either to give up the exploration or to envisage future production. --------------------------------------------------------------------------------------- Like our Facebook: https://www.facebook.com/oilvips Twitter: https://twitter.com/oilvips And Don't forget to subscribe to our channel

When they saw that Sweden’s City of Kiruna couldn’t coexist with the iron mine that lies beneath, city planners had a daring idea. Moving the city 3 kilometers east would save the mining industry and give citizens a chance to reimagine their city. When an executive at IT services company CGI saw a way to collect extensive infrastructure data to support smart, sustainable growth, his team collaborated with the city on a proof of concept. By “seeing” city infrastructure data with Microsoft HoloLens—from pipe material types to subsurface composition data like soil type, Kiruna planners have a leg up on the future.

KEENE 140 DRYWASHER Gold in Wickenburge Arizona . GOLD RUNNERSS
 
02:10
KEENE DRYWASHER Gold in Wickenburge Arizona . GOLD RUNNERSS the dirt was wet or els our results would have been amazing 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 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

Evolution of Risk Management...in Underground Engineering - 2006 Buchanan Lecture by C.Baker
 
01:53:11
The Spencer J. Buchanan Lecture Series on the GeoChannel is presented by the Geo-Institute of ASCE. For more information about the Geo-Institute: http://www.asce.org/geotechnical-engineering/geo-institute/ The 14th Spencer J. Buchanan Lecture in the Department of Civil Engineering at Texas A&M University was given by Clyde N. Baker, Jr., PE, SE on Nov. 17, 2006. "Evolution of Risk Management as a Project Management Tool in Underground Engineering" Abstract: Cost effective foundation design may entail use of mixed foundation systems which can require more accurate and reliable load deformation prediction capability. In the writer's experience, the Menard in-situ pressuremeter test has been very useful in enabling better load deformation prediction with different foundation support systems. Case histories are presented to illustrate five different design concepts: 1) Complex existing foundation conditions required dewatering effots to permit belled caisson construction below the old caissons. 2) Use of piles or drilled shafts as settlement reducers rather than as required structural elements for building support. 3) Use of deeper basement excavation stress release effects in ways to maximize site building capacity. 4) Use of variable length piles under a mat to minimize differential settlement. 5) Re-use of existing deep foundations on one bearing stratum in combination with new foundations on deeper stratum. About Clyde N. Baker, Jr.: Mr. Baker received his BS and MS degrees in Civil Engineering from the Massachusetts Institute of Technology and joined the staff of STS Consultants, Ltd. (formerly Soil Testing Services) in the fall of 1954. Over the past 50 years, he has served as geotechnical engineer for many high rise built in Chicago. He has also served as geotechnical engineer or consultant on seven of the sixteen tallest buildings in the world including the three tallest in Chicago (Sear s, Hancock, and Amoco) and the current two buildings in the world, the Petronas Towers in Kuala Lumpur, Malaysia and 101 Financial Center inTaipei, Taiwan. As a result of his experience, Mr. Baker has developed an international reputation in the design and construction of deep foundations. He has been a leader in using in-situ testing techniques correlated with past building performance to develop more efficient foundation designs. In the Chicago soil profile this has facilitated economical use of belled caissons on hard pan for major structures in the 60 to 70 story height range (such as Water Tower Place, 900 North Michigan, and AT&T) which normally would have required extending caissons to rock at significant cost premium. Mr. Baker has shared his knowledge and experience with his peers through numerous Conference and University lectures, technical articles, papers and publications. He is the recipient of the Deep Foundation’s Institute Distinguished Service Award, the ADSC Outstanding Service Award, ASCE’s Thomas A. Middlebrooks and Martin S. Kapp awards and of three Meritorious Publication Awards from SEAOI including the "History of Chicago Building Foundations 1948 to 1998". He is the author of "The Drilled Shaft Inspectors' Manual" sponsored jointly by the Deep Foundation Institute and the International Association of Foundation Drilling (ADSC).

Digital Geology  - Innovation in Subsurface Learning
 
02:26
Digital Geology is an innovative approach in Subsurface Learning in which geological outcrops are brought into the office environment and augmented reality techniques are used with real geological exhibits (rock slabs, cores, fossils) to provide the experience of hands-on reservoir characterization work combined with digital overlays. Five geological exhibits, representing different scales of geological analysis and investigation (ranging from “basin” scale to “grain” scale) have been constructed and integrated through interactive exercises in the existing learning programs in Shell. Digital Geology is an efficient way to upgrade the quality of existing geological field trips, by having a virtual reconnaissance trips upfront, thus reducing the length of the real field trip and the associated HSSE-exposure. The Digital Geology concept is new in the industry and shows Shell’s commitment to innovation in learning.
Scientists discover vast underground ecosystem of 'deep life' microbes

RESTRICTIONS: Broadcast: NO USE JAPAN, NO USE TAIWAN Digital: NO USE JAPAN, NO USE TAIWAN Deep life studies have revealed a rich subterranean ecosystem within the Earth almost twice the size of the world's oceans. The Guardian reports that Deep Carbon Observatory scientists made boreholes over 5 kilometers deep, and drilled 2.5 kilometers below the seabed to find an underground biosphere containing 'deep life' microbes that may have persisted for thousands or millions of years. These previously unknown lifeforms thrived despite extreme temperature and pressure. They reportedly fed on energy from rocks, and existed in a slow-motion, zombie-like state. The results suggest that 70% of the Earth's bacteria and archaea exist underground, amounting to between 15 and 23 million tonnes of carbon. Among them are barbed Altiarchaealis that live in sulphuric springs and Geogemma barossii, a single-celled organism found in hydrothermal vents on the seafloor, whose cells grow and replicate at 250 degrees Fahrenheit. Researchers have been trying to determine the boundary where life cannot exist, but the deeper they dig, the more life they find. Though there is a temperature maximum set at 251 degrees Fahrenheit, scientists think further exploration using more sophisticated instruments might break that record. RUNDOWN SHOWS: 1.

Subsidence - Video Learning - WizScience.com
 
02:09
"Subsidence" is the motion of a surface as it shifts downward relative to a datum such as sea-level. The opposite of subsidence is uplift, which results in an increase in elevation. Ground subsidence is of concern to geologists, geotechnical engineers and surveyors. Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface causes the creation of voids . If the roof of these voids becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface. This type of subsidence can result in sinkholes which can be many hundreds of meters deep. Several types of sub-surface mining, and specifically methods which intentionally cause the extracted void to collapse will result in surface subsidence. Mining-induced subsidence is relatively predictable in its magnitude, manifestation and extent, except where a sudden pillar or near-surface underground tunnel collapse occurs . Mining-induced subsidence is nearly always very localized to the surface above the mined area, plus a margin around the outside. The vertical magnitude of the subsidence itself typically does not cause problems, except in the case of drainage –rather, it is the associated surface compressive and tensile strains, curvature, tilts and horizontal displacement that are the cause of the worst damage to the natural environment, buildings and infrastructure. Where mining activity is planned, mining-induced subsidence can be successfully managed if there is co-operation from all of the stakeholders. This is accomplished through a combination of careful mine planning, the taking of preventive measures, and the carrying out of repairs post-mining.

Micromechanical study of multiphase flow based on the lattice Boltzmann method
 
03:05
Eduard Puig i Montellà (1), Bruno Chareyre (1), Simon Salager (1), Chao Yuan (1), and Antonio Gens (2), (1) University Grenoble Alpes (UGA), (2) Technical University of Catalonia (UPC) Hydrostatic properties of unsaturated granular materials at the pore scale are evaluated using lattice Boltzmann method (LBM) simulations. Numerical simulations are presented by using the multi­component multiphase Shan­Chen LB model implemented in the open source software Palabos. Practical situations involving multiphase flow include infiltrated rainwater into soil by displacing air and industrial processes such as riser reactors, fluidized beds, dryers, etc. Drainage simulations are conducted in elementary microstructures (static assemblies of 2 or 3). The meniscus shape, the volume of the liquid bridge and the capillary pressure have been analyzed and proven to match theoretical solutions for configurations of 2 and 3 spheres.

Gold prospecting Arizona bedrock
 
02:37
Just had a grate time out there prospecting for gold and took some home .. Love it #gold fever pls subscribe to GOLD RUNNERSS ..thank you guys 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 how to

Multi-contaminant interactions at aquifer-river interfaces
 
47:04
Presented by Stefan Krause - Professor and Chair or Ecohydrology and Biogeochemistry at the University of Birmingham, UK - at the 2018 Emerging Contaminants in the Aquatic Environment Conference. Hyporheic zones at the interfaces between aquifers and rivers are characterized by the spatially and temporally dynamic mixing of groundwater and surface water resources. The mixing of these diverse water sources creates streambed hotspots where different types of legacy and emerging contaminants meet, potentially react or compete for reaction partners. This demands the development of integrated management strategies for groundwater and surface water resources. This talk investigates the organizational principles of drivers and controls of multiple contaminant interactions in hyporheic zones, including examples of different diffuse and point source legacy pollutants as well as emerging contaminants such as engineered nanoparticles and microplastics. The environmental impacts of multiple pollutants on ecosystem functioning (whole stream metabolism, biofilm primary production) are furthermore analyzed in relation to other stressors, such as increasing water temperatures, flood or drought conditions.

Bio-Geo-Alchemy: Biogeotechnical Carbonate Precipitation - 2016 Buchanan Lecture by E. Kavazanjian
 
02:43:57
"Bio-Geo-Alchemy: Biogeotechnical Carbonate Precipitation for Hazard Mitigation and Ground Improvement" Presented October 14, 2016 by Edward Kavazanjian, Jr., Ph.D., P.E., D.GE, NAE Begins at 1:14:28 Also presented: 2015 Terzaghi Lecture, "The Evolution of Specialty Geotechnical Construction Techniques" by Donald Bruce, Ph.D., C.Eng, L. G., L.E.G.,. D.GE, M.ASCE Begins at 7:00 Program: https://ceprofs.civil.tamu.edu/briaud/Buchanan%20Web/Twenty-Fourth%20Buchanan%20Lecture%20Booklet.pdf While the ancient alchemists strove to change lead into gold, modern day bio-geo-alchemists strive to turn sand into sandstone. The bio-geo-alchemy technology that has gained the most attention over the past 15 years is bio-mediated calcium carbonate precipitation hydrolysis of urea (ureolysis), wherein microbes are used to induce precipitation of calcium carbonate (preferably calcite) in granular soils, turning cohesionless sand into a sandstone-like material. More recent research has looked at using other microbially-mediated processes (e.g., reduction of nitrogen, or denitrification) and bio-inspired ureolysis using an agriculturally-derived enzyme to precipitate carbonate in soil. Successes in laboratory testing and limited field trials suggest that these techniques can non-disruptively mitigate the potential for earthquake-induced liquefaction under and around existing facilities, control fugitive dust, and replace Portland cement as a binder in a variety of infrastructure construction applications. Induced carbonate precipitation is just one of many technologies currently being explored in the emerging field of biogeotechnical engineering, including development of root-inspired earth reinforcement and foundation systems, in situ creation of barriers to contaminant transport, soil and groundwater contaminant transformation or sequestration, enhanced soil penetration systems, and motile subsurface investigation probes.

What is Irrigation ? And necessity Of Irrigation
 
05:40
The hub of a center-pivot irrigation system Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection,[1] suppressing weed growth in grain fields[2] and preventing soil consolidation.[3] In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dry land farming. Irrigation systems are also used for cooling livestock, dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the removal of surface and sub-surface water from a given area.
