  Every living organisms living in aquatic ecosystems need dissolved oxygen to survive. Dissolved oxygen is the product of photosynthesis and diffusion and that is the only way water gets oxygen in it. Turbidity has a major impact on dissolved oxygen. Turbidity is how clear the water is and how much sediment suspended in the water. When the water is too turbid like when an algae bloom happens that happen because of high amounts of nitrates. This blocks the sunlight and does allow plants to grow stop dissolved oxygen made from photosynthesis. The acidity in the water is called pH and aquatic organisms live in water with a pH from 5.5 to 9.5. The water neutralizes this acid and this is called alkalinity. E coli can damage a water stream when in high amounts making it not safe to swim.  Conductivity is waters ability to conduct water. This and rapid and extreme water temperature causes stress to aquatic organisms. These are all important terms of the health of a water source.

      Mountain top removal is ruining our mountain state. The effects of mountain top removal are ugly and permanent. The first step they do for MMR is deforestation in which all of the vegetation on the whole mountain so they can begin to blast the over burden up. It is then moved into nearby valleys and streams where they fill in with dirt and this pollutes our streams and their aquatic ecosystems with dissolved minerals and toxic sediments. The loose soil makes flooding a major risk because there is nothing to hold the water back. Then they blast deep into the ground to gather the coal from the coal seams by using a dragline. Blasting near a town or house will cause damage too home and cover everything around the mine with black nasty coal dust. If we keep letting coal companies remove our mountains then we will eventually have no mountains in the mountain state anymore. 

 

 

Mountain top removal

      Many people think mountaintop removal is such a horrible thing and just destroys the Appalachian Mountains. The thing is that it is very important to the state of West Virginia for many different reasons. Surface mining is much more efficient then underground mining. The job is much quicker and doesn’t cost as much money as an underground mine would. Since all the work is above ground and most of the jobs include haling the dirt and coal away, MTR is much safer than underground mining. The great need for truck drivers to haul coal and dirt away increases the amount of jobs that are needed and are available for the community. This is very important because we all know how dangerous coal mining has been in history. Another benefit for mountain top removal is that it creates flat land in mountainous areas that are prime for building on. This helps the economy out when we can build new business and communities on top of reclaim surfaces mining sites. This way the mountain has two advantages. Mountain top removal isn’t as bad as people think it is and can actually be very beneficial to everyone after it has been reclaimed.

lbj's coal formation blog

      Coal is formed when plant life is decayed in swamps 300 million years ago. When these plants died in the swamp they got buried underground with no oxygen and acidic/ anaerobic conditions prevent complete decay. When this happens it forms peat which is like a moss that has a low heat value but will eventually turn into coal over millions of years.

Brian Johnson's coal camp blog post

      Thurmond was built in 1885 used to be a coal town on the edge of the New River in Fayette County West Virginia. There is only 5 white people that live in the town today but back in the 1920’s it used to be booming coal town. Thurmond is owned by the National Park Service for the New River Gorge National River. When Thurmond had 285 people in 1920 it was mostly used from switching trains that came from the mines into trains that hauled coal through the mountains for many of miles. Thurmond was once the site of a Hollywood movie too. The 1987 movie Matewan was filmed right on Main Street since it is one of the last coal towns that looks almost exactly as it did almost 100 years ago. Although there are only 5 residents still living there and the coal town long shut down, long trains filled full with coal continuously pass threw Thurmond everyday.

Brian Johnson's surfaace mining blog

      There are three types of surface mining and the first one is strip mining. Strip mining is where they mine from the surface of the mountain down. The first step is deforestation where all trees and everything else is bulldozed down. Then they blow up the dirt and rock (over burden) and move it to valleys until they reach the coal seam in the earth. The advantages for strip mining are that it is easy, safer, and less expensive to extract from the ground. One big disadvantage is that it pollutes local steams and ecosystems. When it rains the water drains threw the loose dirt and extracts the minerals and washes them into streams causing many of problems.

 

 

 

 

 

 

      Contour mining is another method of surface mining in which they cut along the contour lines in the mountain. This type of mining is used when the slope of the mountain is really steep. Each time they take the overburden off they have to move it to a previously mined location. The disadvantages are landslides and erosion and the overburden to coal ratio. It is time to call it quits on the mining site when you have spend more on moving the overburden than you get from the coal. But some people do think that contour mining is good for West Virginia because of our big steep mountains.

 

 

      The last method of surface mining is the most controversial, mountaintop removal. Mountaintop removal is pretty self explanatory.  They literally take off the top off a mountain sometimes up to 400 feet to get to the coal seams underneath. The only good thing about it is that it is the most effective method of mining but has the most disadvantages.  No matter what the coal companies say the mountain will never be the same as it used to be. For one the mountain is chopped off and it causes extreme pollution to the area and put toxics into the watershed killing them.

Brian Johnson's underground coal notes

There are five different methods of underground coal mining. The first type is the most common type of mining in West Virginia and it is shaft mining. You have probably seen these types of mines before because the only way to get down into the mine is to take an elevator straight down usually past 1,000 feet.  The advantages to shaft mining are that we can get a lot of coal out of the mines with huge machines that do all of the work but the bad thing is that a massive mine explosion could happen if the company isn’t carful.

 

Drift mining- Drift mining is another method of coal mining where the opening of the mine is in the side of the mountain instead of drilling down into the ground when the coal seam meets the surface. The coal miners mine horizontally into the coal seam in the mountain.  Drift mining is one of the easiest ways to mine but it is always not the safest because of the danger of collapsing roofs.

 

 

 

 

Room and pillar mining is an underground mining method where they cut out sections of the coal and leave “pillars” in many “rooms” of coal in parts so the coal will support the roof. The bad thing about these types of mines is the nearly half of the coal that is used for the pillars is left behind and there is a constant danger of the roofs collapsing on top of the miners. In room and pillar mining they can use fewer men to extract coal they can use continuous machines that constantly cut coal out of the mounting without the use of multiple miners.  It is a huge machine that has rotating steel drum tungsten carbide teeth that move 5 tons of coal per minute. Continuous miners are used in drift mining and room and pillar mining and have been around since the 1940’s. Click here to see a continuous miner.

The last method of underground mining is the long wall technique.  This method is highly effective because there are hydraulics machines that hold the roof up while they mine the coal and then after they are all done they retreat and let the roof collapse on itself. It is high effective but dangers of roof collapses are still high.
