  1. Coal mining has changed in many areas since the early days of commercial mining and certainly from the old boom town days of the late 1800’s. New technology and new philosophies make underground mining faster and easier than ever before. But there is a limit to how much coal is available for people to use for energy. The modern market for coal reflects these facts, and the processes used today make coal accessible and appropriate for the needs of modern society. Corrosion Resistant Metals Corrosion resistant metals will play a huge role in the future of the mining industry. Corrosion refers to the process by which metals are oxidized based on chemical reactions. Metals that resist corrosion are valuable for mining, and inside the depths of the mines, metals corrode easily over time due to all the elements that comprise the coal mines. These metals will allow workers to continue extracting coal for longer periods of time without having to replace their tools so often. Recently in Weir Minerals Africa, slurry valves were replaced with corrosion resistant valves and have benefited from less leakage and rapid wear. Proximity Detection Proximity detection technology allows mining companies to keep track of the resources and the people they work with at all times. When a person or object is in the path of a machine, an alert will go off inside the machine. This can save lives in addition to keeping the machine focused on the real targets of the operation. Proximity detection will save time and money, and has helped everyone stay safer inside the mines so far. Ceramic Mineral Processing Technology Ceramic mineral processing uses some of the newest technology to create dense ceramic components for machine parts. Companies like Ceramic Technology Inc. provide ceramic fabrications and mineral process equipment which now line mine processing machinery, reducing noise. This means the companies save time and money with improved, cleaner, and safer operations. And won’t have to use pressure machines like previous generations did. Coal mining has evolved tremendously over the years. The days of dangerous mining are now almost completely gone as miners are safer and better protected than ever with the new technology open to them. The work is now more efficient and the evolution of the mining industry has forever changed the way people participate in and view the collection of coal and other resources.
  2. It's lunch time. You drive your car and go to grocery store for preparing something delicious. You pick chicken and a pre-made salad. Have you noticed that such actions affect environment? How could it be possible? Let me explain. When you go by car, it releases carbon dioxide to the atmosphere. Air gets polluted. The store that you went into, require light which is powered by coal and as you know that coal mining destroy our ecosystem. What about that salad? Its ingredients grown on farm using harmful pesticides and then washed into local streams poisoning the fish and aquatic plants. Water gets polluted. Even chicken transported by trucks that emits poisonous gas. A smallest action of human creates an environmental change. Think of a bigger picture. Humans are completely dependent on mother nature for survival. But, what you give back? Harmful chemicals that pollutes water, carbon monoxide and sulphur dioxide such undesirable gases causing air pollution. We really need to think on this and stop some where. Have you ever wonder which is one of the main reason in determining the nature? Industrial pollution is the main cause. Earlier industries were limited and so they were less harmful to en vironment. But, with growing population several industries evolved on a large scale with massive production. This has depleted certain natural resources damaging the environment permanently. Best example is deforestation which is clearing of forest for sake of production. “ Grow More Trees” is our motto. Do you think we took this seriously? Just to increase production level, what are we doing? Cutting down the trees and cripple the system. Greed can lead to catastrophic accidents and eventually society has to suffer. Mainly primary industries has caused a massive damage to earth especially mining of coal. This has become one of the biggest issue today. Coal, one of the fossil fuel, is mined with an aim of producing electricity. Imagine a day without electricity. I remember a day when the light goes off just for an hour and I was like yelling and calling at electricity office. We really could not live without it. Not even an hour. Now, you might have come to know how coal is important and so its mining as well. But Wait! All good things come with something not acceptable. Have you ever think of how much damage is caused to surface of earth while mining coal? Let me list down all the drastic consequences that comes along with mining of it. 1. Emission of harmful gases deteriorates ambient air quality With an aim to extract coal from underground mines, mining operation is done. Such operation includes drilling, hauling, collection and transportation and this results into emission of harmful gases like methane, sulfur-dioxide, oxides of nitrogen and carbon monoxide . Just like other fossil fuels, combustion of coal produces CO2 affecting the green house effect. This even increase in global warming. This even has major impact like global warming. Don't you think such release of gases will pollute the air? Off-course Yes. Much more air quality deterioration is caused due to opencast mining in which mining operation is carried without any tunnel or shafts. Imagine how much destructive it will be? Such emission leads to serious health hazards with a rapid increase of respiratory disease such as chronic bronchitis and asthma. Really, we need to think on this otherwise the day is no far where we are left alone by nature. Within last few year production of coal is sky-rocketing. You can figure it out how the production of coal has been incresed in china in last few years. 2. Adverse impact to hydrological regime Process of mining, burning the coal and waste storage of coal pollutes the water. How? A flowing water comes into contact of coal mining activities that has exposed rocks. Such rocks contains pyrite, a sulphur bearing mineral. This mineral reacts with water forming sulphuric acid. Such runoff results into a metal rich water that is Acid mine drainage (AMD). How dreadful it would be to those aquatic plants and animals? And what about us? We too are affected as we drink that contaminated water. Other reasons that pollutes the water are erosion of mine benches , overloaded and reject dumps, failing dams and even during discharging of million litres of water itself. “Water is life” But, we have made it such that becomes dangerous to your life. How mean we are? 3. Enormous Land Disturbance Caused due to mining operation Mining operation goes through large scale excavation, creation of negligent land, removal of top soil, dumping of solid waste and cutting of roads. Usually, mine collapse in underground mining and land above it start to sink result into an interruption. News about such catastrophe is frequently heard. But, opencast mining is more destructive than underground mining. It scraps away earth and rock to get coal buried near the surface. It destroy landscapes, forest, wildlife, contaminates ground water and result into air and noise pollution. Such environmental affects are so profound that recovery of it is next to impossible. So, why we become so careless and constantly dig though it affects our environment. 4. Mining causes noise and vibration Do you like someone screaming? No Why? Because it is too unpleasant to our ears. Think of a blast or something weird sound at a high volume. How terrible it might be for our ears. Think of people living around the areas where mining activities takes place. Why? Because such mining operation produces lot of noise and vibration as well. Hundreds of tones of explosives blast in the mining area and this creates a massive noise pollution. Hearing loss of human ears is one of the major consequence of noise. Imagine how dreadful it might be? Beast in forest are more sensitive to such noise and so they are more affected than humans. Want to improve environmental sustainability in industries? There has been established many institutional bodies that offers diploma in Environmental Management. Many of them even offer excellent trainig and one of my friend has experienced best training of workplace environmental at Brisbane in Australia. Being a part of this wonderful nature, each and every individual is responsible for such destruction. Why we have become so greedy that we don't care of its frighting consequences. There is still time to save our nature otherwise it will be too late to sum up everything.
  3. Check out these amazing photos of coal mining and its devastating effects on the landscape in Germany. And people say windmills look ugly!     The photographer is Bernhard Lang. The photo gallery shows aerial photographs of the largest opencast coal mining pit of Germany.   Photographed May 2014.
  4. In these days Japanese government took the worst decision concerning energy: Prime Minister Shinzo Abe is pushing Japan’s coal industry to expand sales at home and abroad. Japan is still fixing the disasters of Fukushima and what is the best thing to do after a nuclear disaster? Expand coal industry! What kind of government would do the contrary of what U.N. told to do for the wellness of planet? A new energy plan approved by Japan’s cabinet on April 11 designates coal an important long-term electricity source. Japan is one of the richest states in the world and this decision is a step backward in the long path to green politics. According to IEA (International Energy Agency) Japan renewable energy share should reach 28.2% of total generation in 2035. With this conservative policy this number has become an impossible projection. The most shocking fact is that this energy plan has been approved a few days after U.N. shouted that fossil fuels are the cause of climate change and that their use must stop right now. This is the clear demonstration that money and profit are more important than environment and people. What's worse than oil? Coal, which represents 48% of total energy consumption, is the main responsible for global warming. The only reason to make investments in coal industry is to produce a large amount of electricity at a low cost. Now the question is: when will governments start to understand that future is important as much as the present?
  5. One might see it as a good development that the federally-owned Tennessee Valley Authority (TVA) is planning to shut down eight coal-burning generating stations across Alabama and Kentucky. While, indeed, this will be a blow to the profiteering coal industry (reducing coal production by 3,300 megawatts in those states), it could be little more than a false triumph in terms of health and the environment. That's because the TVA is planning on replacing those stations with nuclear plants and natural gas facilities. The Obama administration has cracked down on carbon and mercury output, particularly when it is triggered by coal-fired power plants. And TVA board members were obligated to respond by phasing out some of these coal facilities, though not without Republican opposition. Senate GOP leader Mitch McConnell, R-Ky., met with the president of the TVA in an attempt to stop the coal plant shutdowns, albeit unsuccessfully. Mary Anne Hitt, director of the Sierra Club's Beyond Coal Campaign, praised the shutdowns, remarking, "This is a great move for public health, clean air and water, and our climate. It will also help protect families across the southeast from rising energy bills as the cost of coal-generated electricity continues to increase. I grew up in the Smoky Mountains of east Tennessee and went to college at the University of Tennessee in Knoxville, so I know firsthand how much that region has struggled with coal pollution. Residents, businesses, and industries have spoken loud and clear: they want the TVA to provide affordable, reliable, and clean power." Unfortunately, the TVA seems to have no plans for implementing renewable energy, and that is why many environmentalists' reactions to the victory have now soured. According to TVA spokesman Duncan Mansfield, coal usage is "dropping fast as a drilling boom in the U.S. pushes down the price of natural gas, the fuel that competes with coal for power generation." He failed to mention the destructive practices associated with natural gas facilities, particularly fracking and chemical dumping. Currently, TVA executives are looking to build a new 800-megawatt natural-gas-fired plant in either Alabama or Kentucky. But perhaps just as disconcerting to activists is the fact that the TVA is now constructing a new nuclear power plant in Oak Ridge, Tenn., after having signed a contract with the Babcock & Wilcox Company. That company owned the reactor that was destroyed by a nuclear meltdown in the infamous Three Mile Island disaster. The new plant is only the first step in the TVA's campaign to step up its atomic output, in addition to natural gas. Hitt, from the Sierra Club, stressed the importance of replacing these dangerous, unreliable fossil and nuclear fuels with cleaner, safer energy. "TVA's next steps are critical," she said. "The utility must consider the workers and communities and make sure their livelihoods are protected. But we urge the TVA to focus on replacing these retiring coal plants with clean and affordable energy technologies that will help create jobs and affordable electricity for decades to come. Wind and solar power are cleaner and cheaper than fossil fuels like natural gas, and there are dozens of examples of for-profit and public power utilities that are making huge investments in clean energy. "We urge the TVA not to choose to rely on natural gas. It's time to leapfrog over dirty fossil fuels that will continue to exacerbate environmental and public health issues. This is the TVA's choice. They can get their fiscal house in order by developing and deploying groundbreaking energy efficiency programs that deliver real results, and by seizing this moment and leading on clean energy."
