Coal Mining
Transcript: What do we use coal for? Environmental Impact 60% of our coal comes from surface mines. Kentucky, West Virginia, Pennsylvania produce almost half the coal production in the United States. Coal Mining 43 Total Reserves % of Total U.S 37 29 Where can we find coal? Local Coal Mines How much coal is being produced? 5 The first industrial use of coal was in 1788. They heated the coal and drawling out the iron used to make nails. How can we get it? 63 The first coal company was the Leghigh Mining Company in 1820. All the coal that we use today was formed millions of years ago. Coal is sometimes called Burned Sunshine. It is made up of plants that originally got their life from the sun. We get coal through mining. Surface Mining: Coal is at the top of the surface of the earth, usually 200 feet or less. There is no need to dig a shaft. 49 155 Ashley Ruggles Block 1 Mr. Moyer 71 24 Surface Illinois Michigan and Illinois coal are persevered in large basins. 120 Whats it like being a coal miner? All Others What is the history of coal? The united states produces 1 billion ton of coal every year but we use .9 billion and export the rest. Gas masks filters out harmful gas, ankle straps hold the miner's pant legs so they don't get caught in machinery, safety glasses, steel-toed shoes, and a hard hat. Large fans move fresh air through the mine. Miners check the air every 20 minutes to make sure fresh air is moving through the mine to take away harmful chemicals and gases. Underground Mining: Deeply barred coal underground that needs a coal shaft to extract the coal. 54 474 Whats it like being a coal miner? 1.) To make a profit Why do we mine? Electricity: Coal runs the electricity through your house. Electric stove uses about have a ton of coal a year. An electric heater uses two tons a year. Coal isn't the only thing used to make electricity,;oil, natural gas, nuclear power, and hydraulic power are other ways coal is used. Heat: Coal provides heat and power to make paper, glass, and the process the food we eat. Appalachian Fields: from Pennsylvania to Alabama 1914 employment reaches over 180,000 workers. Montana Underground 15 86 Process of Turning Coal into Electricity Coal miners have died a lot in the past from collapses roof of the underground mines. Steel: The iron and steel industries use a special kind of coal in the steel-making process, "metallurgical" coal is made into coke, the main fuel in a blast furnace. The furnace makes pig iron, that, along with scrap metal, in the steel making process. Exports: Exported to other countries like Japan, Italy, Netherlands and Canada. It is formed right out of where plants grow. 1.) Coal is mined and taken to a power plant. By burning coal the ash and sulfur get into the air and pollute the air. High contents of coal being burned is usually where you would find highly acid drainage and the local water table is lower. West Virginia 2.) Coal is burned in a broiler which causes the water in the broiler pipes to become steam.

What is coal? What are the Risk Factors of Being a Coal Miner? Total U.S How do we get it? 2.) Inexpensive and efficient way to generate energy 32 1900 total fatality of coal mining is 13,000 men, woman, and children. 27 Wyoming Far western fields: extend from New Mexico northward through the rocky mountains to Montana and the Great Plains of North Dakota. The Far Western Fields contain up to 100 ft in thickness with large basins, generally low rank, being either lignite or subituminous coal. The coal here is in very high demand because it has less sulfur than Eastern coal. 319 Works Cited 25.3 16.5 14.6 7.8 6.1 29.7 100.0 What is the history of coal? What is the history of coal? Miners usually work 8 hour shifts, sometimes at night. When underground, miners take serious precaution. The miners take training classes so they can work safely in the mines. They wear several items to protect him/her self. Miners wear a self-rescuer, strapped to a miner's belt. What do we use coal for? 69 3.) Most abundant Back in the Carboniferous Age, or coal forming period, there giant ferns and when they died, water and mud washed over them. layers and layers of dead plants were buried under prehistoric forest and seas, the weight of the water and mud compressed these plants, leaving a rich layer of carbon. Miners don't think about the roof collapsing but the long term effect. Coal Worker's Pneumoconiois also know as "black Lung". Black Lung is when the dust from the coal gets into their lungs when they breath it in and can cause cancer. This does not happen right away but can develop over time. There are local mines in Stark County
