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.

South Africa's TauTona mine, real life alchemy, and Halicephalobus Mephisto. Footage from the 2012 documentary, "Down to the Earth's Core". We have travelled into space and looked deep into the universe's depths, but the world beneath our feet remains unexplored and unseen. Now, that's about to change. For the first time in one epic unbroken shot, we embark on an impossible mission - using spectacular computer generated imagery to smash through three thousand miles of solid rock, and venture from our world into the underworld and on to the core of the Earth itself. It's a journey fraught with danger. One thousand feet down we find ourselves inside one of the planet's most volatile places - the San Andreas Fault. Caught between two huge rock slabs, we watch as stress builds and then releases. It unleashes an earthquake and blasts us on towards rivers of molten rock, explosive volcanoes, tears in the Earth's crust and giant tornadoes of liquid metal. But for every danger, there are wonders beyond imagination. Four hundred feet below the surface, a three hundred million year old fossilized forest, with every leaf and every piece of bark perfectly preserved. At one thousand feet down we enter a cave of giant crystals, glistening in deadly 122 degree heat. More than two miles underground we find buried treasure - gold and gems. Deeper still there are valuable resources - salt, oil, coal and iron. And over one hundred miles down we see the sparkling beauty of diamonds. As we descend we piece together our planet's extraordinary story. We rewind time to discover how prehistoric forests became modern-day fuel. 1700 feet down a layer of rock reveals the extraordinary story of the dinosaurs' cataclysmic death. We watch stalactites form and gold grow before our eyes. The deeper we travel into the underworld the more we understand our world above the surface. A bigger picture takes shape - a cycle of destruction and creation, driven by the core that sustains our dynamic planet and makes the Earth the only planet with life in a seemingly lifeless universe. Until, finally, three thousand miles down, we reach the core. Inside it lie the secrets of life as we know it - the magnetic force field that protects life on Earth from the sun's deadly rays, the ancient heat source that keeps our planet alive. Down to the Earth's Core brings the latest science together with breathtaking computer generated imagery. The result is an unmissable journey into an extraordinary world - full of dangers, wonders and secrets. And it's all down there, beneath our feet, right now waiting to be discovered.

https://mocomi.com/ presents : How is Coal Formed? Millions of years ago, a large number of plants and ferns grew on Earth. These plants and ferns died in swamps, around riverbanks and got covered with soil and mud and slowly sank into the ground. As the years passed, the Earth’s heat and the weight of the ground changed these dead plants into coal. To extract coal, it needs to be dug out. Coal is usually found in layers, or seams underground. Learn more about where do we get coal and how does it form with the help of this animated learning module for kids.

Students in HU's undergraduate geospatial technology program and in the school's graduate-level project management program are working on a three-year initiative to scan, validate, and electronically archive maps of 15,000 active and abandoned Pennsylvania coal mines. Helping students understand the context—the multitude of ways that mapping tools and technologies can be applied, in any number of fields—is both a great challenge and a great thrill for Professor Albert Sarvis, who views the mine map grant as an experiential windfall for his students. It's another example of the hands-on projects that HU students undertake as part of the academic experience at HU. For more information on HU and its programs, visit online at www.HarrisburgU.edu

Rocklabs automated systems are all designed to meet specific customer needs and requirements. Our overall aim is simplicity of design and technician/operator friendly. Our design and construction of the system enables the system to be operated by existing technician/operator and maintained by existing plant fitters/mechanics. This minimizes the long term running cost and increases the ease of maintenance. Each System's layout will depend on sample details such as the type of sample, throughput quantity, weight and fineness to be processed per day/month/year. In addition, the degree of automation and the facility where the Automated System will be used are also critical to the design layout. All Automated Systems are designed, built and tested in our factory. A full specification is required from the customer to determine the use of different machines and degree of automation required as well as possible integration in the future. To ensure success, Rocklabs requires customer's samples to be tested. FATs (Factory Acceptance Test) are carried out before the System leaves the factory. Automated Systems can allow for multiple samples or batches to be loaded at the same time. Operator handling is minimised. The entire process is controlled by PLC controllers, including lifters, conveyors, pneumatic actuators, crushers, pulverisers, vibratory feeders, including robots where necessary. Over the last decade, Rocklabs Automated Systems have processed millions of samples, reducing laboratory costs and ensuring that high quality samples are ready for analysis.

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Since the late 1700s steam engines have become a major source of mechanical power. The first applications were removing water from mines. In 1781 James Watt patented a steam engine that produced continuous rotative motion. The engines could be sited anywhere that water and coal or wood fuel could be obtained. By 1883, engines that could provide 10,000 hp had become feasible. Steam engines could also be applied to vehicles such as traction engines and the railway locomotives which are commonly just called steam engines outside America. The stationary steam engine was a key component of the Industrial Revolution, allowing factories to locate where water power was unavailable. Today steam turbines generate about 90% of the electric power in the United States using a variety of heat sources. Steam engines are external combustion engines, where the working fluid is separate from the combustion products. Non-combustion heat sources such as solar power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In the cycle, water is heated into steam in a boiler until it reaches a high pressure. When expanded through pistons or turbines, mechanical work is done. The reduced-pressure steam is then condensed and pumped back into the boiler. In general usage, the term steam engine can refer to either the integrated steam plants (including boilers etc.) such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Specialized devices such as steam hammers and steam pile drivers are dependent on steam supplied from a separate boiler.

MANUFACURE OF PORTLAND CEMENT:Raw Materials: The raw materials required for cement manufacture are. Lime stone which provides calcium. Clay which provides aluminium and silica.Cement is manufactured by two methods they are. Wet process. Dry process. Now let us discuss wet process and dry process detailed.WET PROCESS:In the wet process, first the clay is purified by washing in a wash mill.The lime stone is crushed into small particles and mixed with purified clay in proper proportions to get raw slurry.DRY PROCESS: In the dry process the raw materials are mixed in proper proportions.The mixture is dried, pulverized (Crushed into fine particles) and made uniform. The resulting powder is called "raw material".The raw slurry or raw meal, obtained by one of wet or dry process called charge. Charge is introduced into a rotary Kiln.The rotary kiln consists of a steel cylinder about 150meters long and 4meter diameter and rotates 30 to 60 turns per hour.At one end of the cylinder a screw conveyer is arranged which slowly allows the charge into the cylinder.The other end of the cylinder, a burneris arranged coal or burning oil is burnt at this end.The charge entering the cylinder slowly moves towards the hot end.At the burning end of the kiln, the temperature is around 1700 to 1900degrees centigrade, at this end some chemical reactions takes place between calcium oxide and aluminium silicates.Mixture of calcium silicates and calcium aluminates is formed.The resultant product consists of gray hard balls called clinker cement.Clinker cement is cooled, ground to fine powder and mixed with 2 to 3 percent of gypsum.

This is the first testing of the mining robot at the Centre for Mining Innovation in the Simulated Stope Test facility in Johannesburg, South Africa. More info at www.csir.co.za This robot is designed to go into a gold mine stope before miner entry and analyze the hanging-wall (Ceiling) for potentially unstable areas. This information is then available to all the miners before they enter the stope. It is used for two outcomes. Mitigating strategies to combat the hanging wall collapse can be assimilated, and all the miners are now aware of where the most dangerous areas of the stope are, and can avoid them. The simulated test stope is a custom built facility that enables the robot to be tested on a number of different scenarios, without having to make the trip underground to the different places. The stope foot wall is 6mx3m, with a hanging wall of 5mx2m. The stope can be tilted from horizontal to beyond 20 degrees. The stope width can be varied, currently it is a 1m. The footwall surface can be varied from stable to unstable loose rock. The hanging-wall can be reconfigured to include a simulated unstable area that can be placed at a number of positions in the hanging wall tiled design. The position of the mining face can be varied between up-dip, down-dip and breast mining. The position and number of wooden pillar supports can be varied. The position and design of the simulated wooden packs around the stope can be varied. The stope is available for commercial use for testing mining equipment and processes.

Doug Tompkins is a longtime wilderness advocate, mountaineer, organic farmer, activist, and philanthropist. But his first career was in business. He founded The North Face outdoor gear retailer in the 1960s, and then cofounded Esprit clothing, retiring from that in 1990 to concentrate on conservation work. In 1992, Tompkins founded the Foundation for Deep Ecology, a philanthropic effort devoted to root causes of environmental crises; soon after, he started the Conservation Land Trust and, with his wife Kris, Conservacion Patagonica, focused on creating large-scale protected natural areas in Chile and Argentina. Tompkins has also helped produce numerous campaign-related exhibit format books on topics ranging from industrial forestry, factory farming, coal mining, and global energy crises, among others. A consistent principle that informs Tompkins activities is that the "present eco-social crisis demands a response—that individuals who recognize the great unraveling of natural and human communities across the globe have a responsibility to act to stop it." Working to reverse the extinction crisis and build a more sane and sustainable culture requires both defensive and proactive strategies. Tompkins's earliest conservation activism sprang from his love for wilderness and experience as a mountaineer. Climbing trips around the globe provided a disturbing view of how wild nature everywhere was under assault by human activity. His ecological worldview deepened during the 1970s and 1980s through a self-guided immersion in ecological literature including the writings of Norwegian philosopher and mountaineer Arne Naess, father of the deep ecology movement. Tompkins has written, "that the influences of Arne Naess, John Muir, David Ehrenfeld, Paul Shepard, Henry David Thoreau, Aldo Leopold and many others put me so firmly on a 'deep' ecological path." By the late 1980s Tompkins saw that the consumer culture that he'd helped promote was a destructive manifestation of an industrial growth economy toxic to nature. He decided to devote his wealth to endow an environmental foundation with an activist orientation. The foundation has embodied the idea that strategic philanthropy can support innovative, biocentric activists tackling root causes—not merely symptoms—of ecological destruction; vigorous and uncompromising advocacy on behalf of wild nature.

The economic development of one country is dependent upon the ability of the authorities to set up a highly suitable, competitive and reliable electricity sector. Why is natural gas better than coal boilers? Only when there is extreme environmental pressure or substantial reduction in loads that conversion from coal to 100% natural gas is possible. Not until the 20th century until natural gas was used for production of energy, it was dismissed as a useless byproduct of crude oil production until then. But now natural gas accounts for 23 percent of the world's energy consumption and still growing. The International Energy Agency predicts that the demand for natural gas will grow by approximately 44 percent through 2035. Natural gas is the cleanest-burning conventional fuel not to mention it has been one of the most economical energy sources. It is an environmentally friendly and efficient source of energy. It produces lower levels of greenhouse gas emissions than heavier hydrocarbon fuels such as coal and oil. Natural gas fuels electric power generators, heats buildings and is used as a raw material in many consumer products, such as those made of traditional plastics. However, natural gas has never been a cheaper fuel than coal. Coal is one of the longest-used and is considered as the most abundant fossil fuels on Earth. Coal mining has been going on since then 17th century. Coal burning boilers have also been around for a long time, and while they may not always be popular, these machines have some definite advantages in terms of costs and simplicity. Because it is the most abundant it is the cheapest form of fossil fuel to burn. But coal boilers on the other hand have harmful effects on the environment and human health. Its emissions contain sulfur combines with air to create the poison gas sulfur oxide. When this gas releases into the atmosphere, it causes polluting rain. Extracting coal from mines further damages soil and water resources, adding to the disadvantages of using coal burning boilers. While coal prices are expected to remain stable natural gas prices are expected to increase as higher cost natural gas reserves need to be developed to meet growing demand and offset losses from depleting gas wells. On the other hand, natural gas based technologies have a capital cost advantage. Whatever the costs may be, don't you think it is better to use natural gas rather than the coal boilers? Even though natural gas is more costly than coal boilers it is less harmful to the environment and to human health. It is always better to take into considerations the things that are more important than money. It is not wise to be thrifty over something that in a long run would back fire on you and worst your kids. Long term effects of coal boilers are scarier than the costs in terms of money that it will bring us today. Environmental effects and health issues will sure be more costly in the future.
