They quickly called upon John Williams, the assistant foreman. The three employees hurried to escape and notify superintendent Robert Groves, who immediately ordered an evacuation, although he withheld the severity of the situation. Unfortunately, the other three men who were stationed in this vein could not escape in time and the fierce waters of the Susquehanna took their lives. While millions of gallons of water flooded into the mine, thirty-three men managed to catch the last elevators at the May shaft, but forty-five others remained trapped, desperately seeking their own outlet. During the first sixty four hours of the emergency, an estimated 2.7 million gallons of water per minute streamed underground from an enormous whirlpool near the riverbank. Down below, thirty-two men wandered in two separate groups until they managed to escape through the abandoned Eagle air shaft. Pennsylvania Coal Company surveyor, Joe Stella, led the first group of seven. He not only knew the mines well, but also possessed maps which allowed his group to find a direct course to the opening. The second group, led by Myron Thomas, consisted of twenty-five men who wandered for hours before they found their way to safety. Unfortunately, twelve of the original remaining bodies have never been recovered. Thousands of bails of hay and hundreds of railroad ties were also added. Culm, dirt, and rock along with over 50 coal and railroad cars barely stopped the river. Finally they diverted the river around Wintermoot Island by building dams at both ends of the island. Once they pumped the water out between the dams the size of the hole was evident. Tons of clay and rock were poured into the hole and a concrete cap was placed on top of the opening. They then pumped much of the water out of the mine to look for the 12 missing miners. How could this tragedy have happened? The original plan was to keep 50 feet of rock and coal between the workings and the river bottom. The Knox company wanted this to be lowered to 35 feet. Mine inspectors deemed this ok as it would be sufficient to stand up to the river. At this point the seam of coal sloped up towards the river in what is known as an anticline. Company owners kept pushing the miners closer and closer to the river bottom until the rock could no longer support the river. At the point where the river broke through the rock was only 5 to 6 feet thick! This disaster ended deep mining in the Wyoming valley as almost all of the coal company’s mines connected.

All the 21 miners trapped underground were confirmed dead after a coal mine accident took place on Saturday in northwest China's Shaanxi Province. Local authorities confirmed that all the trapped have been found dead. There were 87 miners working underground when a roof collapsed at the Lijiagou coal mine of the Baiji Mining Co., Ltd. in the city of Shenmu at around 4:30 p.m. After the accident, 66 of the miners were lifted from underground to safety and 21 remained trapped. An investigation into the incident is underway.

Silent black & white archival film clip from Benjamin Harrison Hay's Footage of a Pennsylvania Colliery, ca. 1930-1940. Hay's footage shows the mining village of Buck Run, located about 45 miles west of Allentown, PA built for operators, managers and employees of the Buck Run Coal Company which was in operation from 1902 until 1950. The original mine owner James B. Neale was socially progressive and wanted to create a real community for the benefit of his workers. By 1925 the town boasted a school, an infirmary, a community recreation facility, a company store and several churches, in addition to homes with running water, electricity and steam heat. Benjamin Harrison Hay was Neale's general manager, vice president and brother in law who assumed control of the company upon Neale's death in 1943. Buck Run Coal was bought out was bought out by Reading Anthracite Company in 1950 and the social experiment came to an end. Very little of the original company town remains today. This clip shows a steam shovel loading processed coal onto a rail car and workers entering and returning from the mine.

(9 Jun 2017) President Donald Trump hailed the opening Thursday of a new coal mine as proof deregulation is helping bring jobs to the industry, even though plans for the mine's opening were made well before Trump's election. Corsa Coal Corp. will supply coal used in making steel and is expected to generate up to 100 fulltime jobs. The company said it decided in August to open the Acosta mine 60 miles south of Pittsburgh after a steel industry boom drove up prices for metallurgical coal. Under a tent perched hundreds of feet above a freshly dug coal pit, about 200 miners, business leaders, and politicians celebrated amid the surge of enthusiasm for the industry. Mining headgear lay atop red, white, and blue table cloths labeled "Make Coal Great Again." Democratic Gov. Tom Wolf said the mine was part of an effort to bring back jobs and industry to the state. Pennsylvania awarded a $3 million grant for the project. "We have not always capitalized on our standing as one of the world's leaders in these resources, but we're changing that," Wolf said. Trump has made reversing the decades-long decline in coal mining the central tenet of his environmental policy, blaming federal regulations aimed at curbing planet-warming carbon emissions for job losses in the industry. Trump and Environmental Protection Agency Administrator Scott Pruitt have targeted laws that protected waterways from coal waste and required states to slash carbon emissions from power plants. About a dozen protesters chanted in opposition to the mine at the opening. Trump noted the impending opening of the mine last week during his speech announcing the nation's withdrawal from the Paris climate accord. He said then he had hoped to attend the event; he participated via recorded video message, taking partial credit for the opening.

Coal mining in the Netherlands 1100-1974 Coal mining in Limburg, a province of the Netherlands, has taken place since the 16th century. Near the Augustinian Abbey of Rolduc, coal is found very close to the surface. The abbey owned the coal, and beginning in the 16th century hired local miners to extract the coal for sale as fuel. The true extent of the coal reserves in the south-east corner of Limburg first became apparent in 1870, when the wealthy Count Marchant and Ansembourg of Brussels ordered the first boreholes to be drilled near Eygelshoven, and a substantial seam of coal was found at a depth of 154 metres. The demand for coal had grown explosively as a result of increased industrialization and urban expansion, but the national governments regarded any form of interference in the extraction and sale of this fuel as unnecessary. Thus it came about that the first concessions for the extraction of coal in South Limburg were granted without hesitation to foreign firms, although most of the coal consumed in the Netherlands was imported from Germany, and Dutch investors preferred to invest their capital in foreign countries, such as in Russian government loans, American railways, and Hungarian waterworks.

New video up! "IS TESLA DOOMED??" https://www.youtube.com/watch?v=7j0iaVmQKlQ --~-- The coal industry in the US is almost dead, but it wasn’t renewables that killed it. Get new updates straight to your inbox here https://teslanomics.co/join "The biggest contributor to coal and nuclear plant retirements has been the advantaged economics of natural gas-fired generation,” says a recent report by the Department of Energy. It also found that the rise of renewable energy, such as wind and solar, hasn’t yet created any problems for reliability and resilience of the electricity grid. The report also recommends that the department shouldn’t intervene in energy markets, such as using funds to support coal. Between 2012 and 2017, the US shut approximately 50 gigawatts (GW) of coal-fired generation capacity. If planned retirements are taken into consideration, the future for coal looks even bleaker. When President Obama was in office he created the Clean Power Plan which was aimed at lowering the CO2 emissions from the US by capturing some of the carbon emitted and increasing the mix of renewable forms of energy like Wind and Solar. In March of 2017, the Trump administration repealed this hoping it would, as he said “save the coal industry” however the report from the DOE suggests otherwise. Their report predicts into the future we’ll see more and more natural gas and less coal and nuclear. One of the main reasons is because of how much more efficient Natural Gas is compared to Coal and Nuclear. While Coal and Nuclear are similar regarding the heat generated during the process of creating electricity, the heat generated using Natural Gas has continued to decline, giving it a greater overall efficiency. The nail in the coffin for the solar industry could be renewables which combined with Natural Gas, will deliver the final blow the coal industry, laying it to rest once and for all. #hallelujah A big reason for this is because of the cost of renewables. Some forecasts suggest that the levelized average cost of electricity (LCOE) per kWh will drop significantly by 2025 making Solar from PhotoVoltaic panels and onshore wind the cheapest in the world. And we’re already seeing a huge spike in Solar investments here in the US in recent years, now accepting for almost 10% of the overall grid. So I want to say thank you to Rick Perry, for ordering this study and helping us move closer towards a brighter future where not only is our energy better for the environment, but cheaper and more sustainable as well. In fact, he will probably come around once he realizes how many more jobs the renewable energy industry is creating. His own department put out a report in showing that the Solar industry alone employed more than double the number of coal employees across the US. Like any high-level figures though, this metric didn't tell the true story as there was a job disparity across the states. Coal was by far the bigger employer in some areas still. But the point here is that there is indeed a big market for energy workers in the US and just because the Coal industry is vanishing, it doesn’t mean the jobs will vanish as well, they’ll likely just change slightly. // Sources https://www.nytimes.com/interactive/2017/04/25/climate/todays-energy-jobs-are-in-solar-not-coal.html https://qz.com/1061246/a-new-department-of-energy-report-explains-why-coal-is-dying-in-the-us/ // New here?

“The Shuttle Car Operator” is 1960s-era color film taking the viewer deep inside a bituminous coal mine to learn more about the coal-mining industry. The camera takes us into cramped spaces as drills make their way through the earth (mark 01:15) and coal hauled away on trolleys called shuttle cars. But the job of a shuttle car operator is one of the most dangerous in the coal mining industry, we’re told at mark 02:10, with one out of every seven transportation injuries involving shuttle car operators. To ensure safety the film discusses the importance of proper car maintenance and proper training of employees. Numerous scenes of shuttle cars in the bowels of the earth follow as the narrator continuously reminds the viewer of the importance of being vigilent and on the lookout for any physical hazards that may impede movement. Starting at mark 04:45 the film reminds of the viewer of those men who “paid with their lives” as crews are shown at work including checking ventilation shafts and removing hazards — though “failure to think about safety” leads to a (staged) fatality at mark 07:55. Other accidents follow, the result of workers too engaged in conversation and oblivious to changes in their underground environment, or those inadequately trained. If an operator is trained and alert, we’re told at mark 15:50, such tragedy can be averted. First introduced in the 1930s, shuttle cars are batch haulage vehicles in the underground mining industry. Shuttle cars are designed to work as a system with continuous miners, efficiently removing cut material from the working face and maximizing the productivity of the entire section. Heavy-duty, high-power drive trains enable our shuttle cars to haul heavy loads in the most difficult conditions. Traction motors power the permanent four-wheel drive system. The cast pivot axles are virtually indestructible, while the heavy-duty conveyors and abrasion-resistant conveyor decking improve reliability and durability.

What is COAL SEAM FIRE? What does COAL SEAM FIRE mean? COAL SEAM FIRE meaning - COAL SEAM FIRE definition - COAL SEAM FIRE 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 A coal seam fire or mine fire is the underground smouldering of a coal deposit, often in a coal mine. Such fires have economic, social and ecological impacts. They are often started by lightning, grass, or forest fires, and are particularly insidious because they continue to smoulder underground after surface fires have been extinguished, sometimes for many years, before flaring up and restarting forest and brush fires nearby. They propagate in a creeping fashion along mine shafts and cracks in geologic structures. Coal fires are a serious health and safety hazard, affecting the environment by releasing toxic fumes, reigniting grass, brush, or forest fires, and causing subsidence of surface infrastructure such as roads, pipelines, electric lines, bridge supports, buildings and homes. Whether started by humans or by natural causes, coal seam fires continue to burn for decades or even centuries until either the fuel source is exhausted, a permanent groundwater table is encountered, the depth of the burn becomes greater than the ground’s capacity to subside and vent, or humans intervene. Because they burn underground, coal seam fires are extremely difficult and costly to extinguish, and are unlikely to be suppressed by rainfall. There are strong similarities between coal fires and peat fires. Across the world, thousands of underground coal fires are burning at any given moment. The problem is most acute in industrializing, coal-rich nations such as China. Global coal fire emissions are estimated to cause 40 tons of mercury to enter the atmosphere annually, and to represent three percent of the world's annual CO2 emissions. Coal seam fires can be divided into near-surface fires, in which seams extend to the surface and the oxygen required for their ignition comes from the atmosphere, and fires in deep underground mines, where the oxygen comes from the ventilation. Mine fires may begin as a result of an industrial accident, generally involving a gas explosion. Historically, some mine fires were started when bootleg mining was stopped by authorities, usually by blowing the mine up. Many recent mine fires have started from people burning trash in a landfill that was in proximity to abandoned coal mines, including the much-publicized Centralia, Pennsylvania, fire, which has been burning since 1962. Of the hundreds of mine fires in the United States burning today, most are found in the state of Pennsylvania. Some fires along coal seams are natural occurrences. Some coals may self-ignite at temperatures as low as 40 °C (104 °F) for brown coal in the right conditions of moisture and grain size. The fire usually begins a few decimeters inside the coal at a depth in which the permeability of the coal allows the inflow of air but in which the ventilation does not remove the heat which is generated. Two basic factors determine whether spontaneous combustion occurs or not, the ambient temperature and the grain size: The higher the ambient temperature, the more quickly the oxidation reactions proceed. The grain size and structure determine its surface area. Kinetics will be limited by availability of reactant, which in this case is carbon exposed to oxygen. Wildfires (lightning-caused or others) can ignite the coal closer to the surface or entrance, and the smouldering fire can spread through the seam, creating subsidence that may open further seams to oxygen and spawn future wildfires when the fire breaks to the surface. Prehistoric clinker outcrops in the American West are the result of prehistoric coal fires that left a residue that resists erosion better than the matrix, leaving buttes and mesa. It is estimated that Australia's Burning Mountain, the oldest known coal fire, has burned for 6,000 years. Globally, thousands of inextinguishable mine fires are burning, especially in China where poverty, lack of government regulations and runaway development combine to create an environmental disaster. Modern strip mining exposes smoldering coal seams to the air, revitalizing the flames.

(5 Jun 2018) Dozens of activists opposed to the development of coal-fired power plants took to the streets of Nairobi on Tuesday. A Chinese company is tipped to help finance and construct the proposed plant in the historic port town of Lamu, whose old town is a listed UNESCO World Heritage site.
