What is OPEN-PIT MINING? What does OPEN-PIT MINING mean? OPEN-PIT MINING meaning - OPEN-PIT MINING definition - OPEN-PIT MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is, where the overburden (surface material covering the valuable deposit) is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for sand, cinder, and gravel). For minerals that occur deep below the surface—where the overburden is thick or the mineral occurs as veins in hard rock—underground mining methods are used to extract the valued material. Open-pit mines that produce building materials and dimension stone are commonly referred to as "quarries." Open-pit mines are typically enlarged until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic. When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid wastes. However, some form of water control is usually required to keep the mine pit from becoming a lake, if the mine is situated in a climate of considerable precipitation or if any layers of the pit forming the mine border productive aquifers.

What is SHAFT MINING? What does SHAFT MINING mean? SHAFT MINING meaning & explanation
What is SHAFT MINING? What does SHAFT MINING mean? SHAFT MINING meaning - SHAFT MINING definition - SHAFT MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation is underground, it is called a winze or a sub-shaft. Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called Raises. A shaft may be either vertical or inclined (between 45 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of the proposed shaft and ground conditions allow then raise boring may be used to excavate the shaft from the bottom up, such shafts are called borehole shafts. Shaft Sinking is one of the most difficult of all development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Historically mine shaft sinking has been among the most dangerous of all mining occupations and the preserve of mining contractors. Today shaft sinking contractors are concentrated in Canada and South Africa. The most visible feature of a mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist used the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground). The headframe will also contain bins for storing ore being transferred to the processing facility. At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for men, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out of the mine. Beneath the Collar the part of the shaft which continues into the ground is called the Shaft Barrel. At locations where the Shaft Barrel meets horizontal workings there is a Shaft Station which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest Shaft Station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a Loading Pocket is excavated on one side of the shaft at this location to allow transfer facilities to be built. Beneath the lowest Shaft Station the shaft continues on for some distance, this area is referred to as the Shaft Bottom. A tunnel called a Ramp typically connects the bottom of the shaft with the rest of the mine, this Ramp often contains the mine's water handling facility, called the Sump, as water will naturally flow to the lowest point in the mine. Shafts may be sunk by conventional drill and blast or mechanised means. The industry is gradually attempting to shift further towards shaft boring but a reliable method to do so has yet to be developed. The shaft lining performs several functions; it is first and foremost a safety feature preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into and lastly a smooth surface to minimise resistance to airflow for ventilation. In North and South America, smaller shafts are designed to be rectangular with timber supports. Larger shafts are round and are concrete lined. Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind Shaft Forms in Lifts of 6m as the shaft advances (gets deeper).

What is TRADITIONAL MINING? What does TRADITIONAL MINING mean? TRADITION MINING meaning - TRADITIONAL MINING definition - TRADITIONAL MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Traditional mining, also known as old-school mining, is a mining method involving the use of simple manual tools, such as shovels, pickaxes, hammers, chisels and pans. It is done in both surface and underground environments. Until the early 1900s, traditional mining was widely used throughout the world. It is still a used mining method in some countries, including Colombia and Peru in South America and Niger in Africa. In traditional surface and underground mining, hammers and chisels with pickaxes and shovels are used. Minecarts are used to move ore and other materials in the process of mining. Pans are used for placer mining operations, such as gold panning. The traditional method of cracking rock was fire-setting, which involved heating the rock with fire to expand it. Once the rock was heated by fire it was quenched with water to break it. Fire-setting was one of the most effective rock breaking methods until 1867 when Alfred Nobel invented dynamite. Traditional mining operations have created some of the largest handmade features on Earth, such as the Big Hole open pit mine in South Africa, which is claimed to be the largest hole on Earth excavated by hand.

EPB TBM by CREG rep by Thai Robotics
Earth Pressure Balance Earth pressure balance, or EPB, is a mechanized tunneling method in which the excavated material is used to support the tunnel face whilst it is being plasticised using foam/slurry & other additives to make it transportable and impermeable. The excavated material is transported into the tunnel boring machine (TBM) via a screw conveyor arrangement which allows the pressure at the face of the TBM to remain balanced without the use of slurry. EPB Tunnel Boring Machines are mainly designed for soft soils containing water under pressure. The EPB TBM can handle loose sedimentary deposits with large boulders and high water table. The excavated material is transported by a screw conveyor from the excavation chamber to the belt conveyor. The combination of the output of the screw conveyor and the advance rate of the TBM ensures that the support pressure in the excavation chamber can be exactly controlled. Continuously monitoring of the state of balance in the excavation chamber by means of earth pressure sensors, allows the operator to control and synchronize all tunneling parameters. It allows high advance rates and reduces the risk of changes at the surface. To improve the ground conditions for EPB tunnelling several conditioning materials can be injected through the cutter head and the bulk head. By changing the ground conditions tunnelling in soils containing gravel, sand or water or in unstable geology is also possible The cutter head of the machine will be designed specially for the ground conditions of the project. Depending on the requirements the head will be equipped with disc cutters or rippers, or a combination of both. All cutter heads will have an optimized opening ratio.

What is PRIMARY SECTOR OF THE ECONOMY? What does PRIMARY SECTOR OF THE ECONOMY mean? PRIMARY SECTOR OF THE ECONOMY meaning - PRIMARY SECTOR OF THE ECONOMY definition - PRIMARY SECTOR OF THE ECONOMY 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 The primary sector of the economy is the sector of an economy making direct use of natural resources or exploit natural resources. This includes agriculture, forestry, fishing and mining The manufacturing industries that aggregate, pack, package, purify or process the raw materials close to the primary producers are normally considered part of this sector, especially if the raw material is unsuitable for sale or difficult to transport long distances. Primary industry is a larger sector in developing countries; for instance, animal husbandry is more common in Africa than in Japan. Mining in 19th-century South Wales provides a case study of how an economy can come to rely on one form of activity. Canada is unusual among developed countries in the importance of its primary sector, with the logging and petroleum industries being two of Canada's most important. However, in recent years, the number of terminal exchanges have heavily reduced Canada's primary industry, making Canadians rely more on quaternary industry. In developed countries primary industry has become more technologically advanced, for instance the mechanization of farming as opposed to hand picking and planting. In more developed economies additional capital is invested in primary means of production. As an example, in the United States corn belt, combine harvesters pick the corn, and spray systems distribute large amounts of insecticides, herbicides and fungicides, producing a higher yield than is possible using less capital-intensive techniques. These technological advances and investment allow the primary sector to require less workforce and, this way, developed countries tend to have a smaller percentage of their workforce involved in primary activities, instead having a higher percentage involved in the secondary and tertiary sectors. Developed countries are allowed to maintain and develop their primary industries even further due to the excess wealth. For instance, European Union agricultural subsidies provide buffers for the fluctuating inflation rates and prices of agricultural produce. This allows developed countries to be able to export their agricultural products at extraordinarily low prices. This makes them extremely competitive against those of poor or underdeveloped countries that maintain free market policies and low or non-existent tariffs to counter them. Such differences also come about due to more efficient production in developed economies, given farm machinery, better information available to farmers, and often larger scale.

What is a petroculture? Conjectures on energy and global culture
How can you use energy as a critical component of cultural and literary analysis? Does making a link between a specific energy system and a previously defined literary or cultural period, movement, or aesthetic form open up new ways of analyzing texts and cultural forms? While the energy humanities have insisted (correctly) that we imagine modernity as deeply shaped by fossil fuels, the outcome of this energy periodization is different than we might hope or imagine. This talk will outline the critical possibilities and limits that come with the introduction of energy into social and cultural analysis.

What is ENVELOPE? What does ENVELOPE mean? ENVELOPE meaning, definition & explanation
What is ENVELOPE? What does ENVELOPE mean? ENVELOPE meaning - ENVELOPE pronunciation - ENVELOPE definition - ENVELOPE explanation - How to pronounce ENVELOPE? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. An envelope is a common packaging item, usually made of thin flat material. It is designed to contain a flat object, such as a letter or card. Traditional envelopes are made from sheets of paper cut to one of three shapes: a rhombus, a short-arm cross, or a kite. These shapes allow for the creation of the envelope structure by folding the sheet sides around a central rectangular area. In this manner, a rectangle-faced enclosure is formed with an arrangement of four flaps on the reverse side. When the folding sequence is such that the last flap to be closed is on a short side it is referred to in commercial envelope manufacture as a pocket - a format frequently employed in the packaging of small quantities of seeds. Although in principle the flaps can be held in place by securing the topmost flap at a single point (for example with a wax seal), generally they are pasted or gummed together at the overlaps. They are most commonly used for enclosing and sending mail (letters) through a prepaid-postage postal system. Window envelopes have a hole cut in the front side that allows the paper within to be seen. They are generally arranged so that the receiving address printed on the letter is visible, saving the sender from having to duplicate the address on the envelope itself. The window is normally covered with a transparent or translucent film to protect the letter inside, as was first designed by Americus F. Callahan in 1901 and patented the following year. In some cases, shortages of materials or the need to economize resulted in envelopes that had no film covering the window. One innovative process, invented in Europe about 1905, involved using hot oil to saturate the area of the envelope where the address would appear. The treated area became sufficiently translucent for the address to be readable. As of 2009 there is no international standard for window envelopes, but some countries, including Germany and the United Kingdom, have national standards. An aerogram is related to a lettersheet, both being designed to have writing on the inside to minimize the weight. Any handmade envelope is effectively a lettersheet because prior to the folding stage it offers the opportunity for writing a message on that area of the sheet that after folding becomes the inside of the face of the envelope. The "envelope" used to launch the Penny Post component of the British postal reforms of 1840 by Sir Rowland Hill and the invention of the postage stamp, was a lozenge-shaped lettersheet known as a Mulready. If desired, a separate letter could be enclosed with postage remaining at one penny provided the combined weight did not exceed half an ounce (about 13 grams). This was a legacy of the previous system of calculating postage, which partly depended on the number of sheets of paper used. During the U.S. Civil War those in the Confederate States Army occasionally used envelopes made from wallpaper, due to financial hardship. A "return envelope" is a pre-addressed, smaller envelope included as the contents of a larger envelope and can be used for courtesy reply mail, metered reply mail, or freepost (business reply mail). Some envelopes are designed to be reused as the return envelope, saving the expense of including a return envelope in the contents of the original envelope. The direct mail industry makes extensive use of return envelopes as a response mechanism. Up until 1840, all envelopes were handmade, each being individually cut to the appropriate shape out of an individual rectangular sheet. In that year George Wilson in the United Kingdom patented the method of tessellating (tiling) a number of envelope patterns across and down a large sheet, thereby reducing the overall amount of waste produced per envelope when they were cut out. In 1845 Edwin Hill and Warren de la Rue obtained a patent for a steam-driven machine that not only cut out the envelope shapes but creased and folded them as well. (Mechanised gumming had yet to be devised.) The convenience of the sheets ready cut to shape popularized the use of machine-made envelopes, and the economic significance of the factories that had produced handmade envelopes gradually diminished. As envelopes are made of paper, they are intrinsically amenable to embellishment with additional graphics and text over and above the necessary postal markings. This is a feature that the direct mail industry has long taken advantage of—and more recently the Mail Art movement. Custom printed envelopes has also become an increasingly popular marketing method for small business. Most of the over 400 billion envelopes of all sizes made worldwide are machine-made.

Historical Materialism  | Historical Materialism Explained
Historical materialism is a methodological approach of Marxist historiography that focuses on human societies and their development over time, claiming that they follow a number of deterministic laws. This was first articulated by Karl Marx (1818–1883) as the materialist conception of history. It is principally a theory of history according to which the material conditions of a society's way of producing and reproducing the means of human existence or, in Marxist terms, the union of its productive capacity and social relations of production, fundamentally determine its organization and development. …………………………………………………………………………………..

Data Science Storytime - Ep. #4, Building A Cyborg Company
Subscribe in iTunes: https://itunes.apple.com/us/podcast/data-science-storytime/id1178167741?mt=2 Kyle and Kevin are back, this time discussing the concept of a ‘cyborg company’. What exactly is a cyborg company and how is it relevant? Kyle explains that like the part-man part-machine cyborg, the modern company has machine parts and human parts, each with its own distinct strengths and weaknesses. Can you identify your company’s machine parts? Why should you even bother trying? Human judgement oriented companies are doomed to fail. Purely machine driven companies also have major shortcomings. They aren’t creative and won’t value life. Listen in on Kyle and Kevin’s take on how to go about building a ‘cyborg company’ that combines the best of both worlds.
