Advantages And Disadvantages Of Strip Mining

When asked to think of coal mining, what comes to mind? A mountain with a hole cut into the side of it with a set of railroad tracks disappearing into it? Maybe an old mine car or two full of some rocks or coal, with a pickaxe and shovel leaning against it. A few guys with hard hats covered in a black powder coming walking out of the mine pushing a car or two full of coal. The technology has advanced but the process is basically still the same as well as the outcome. Coal is retrieved from underground and taken to factories to be burnt to create electricity or to fuel the steel mills.

The process to mine the coal is quite complex. First, surveyors are called on site to document the layout of the land so that in can be restored to

The process of transferring the cost of metal ores and other minerals removed from the earth to an

Some important things made from metals include cars, bridges, appliances, power generation, infrastructure, and obviously many more. Everything electrical needs copper, (which is mined), to function. A major concern for the mine is that it will pollute and destroy the nearby natural

Mineralogy- An important part of Geology is the study of Minerals, their physical properties, structure, and chemistry. It helps us understand how they react with one another depending on the circumstances including weathering, fire, how deep, with living or non-living organisms. Minerology is broad and interesting field of study.

To recover diamonds, the industry is using modern mining methods and a more clinical approach to sustainability of mining and therefore the impact on the environment is being minimized while the benefits to the communities and countries where they are found are being maximized. These benefits are

Surface mining began to replace traditional underground mining around WWII (Bozzi 116). Rather than digging into the mountain to extract the coal, strip mining involves removing the overlying soil and rock that covers the coal deposits (Lutz 1). It seemed appealing at first because the previous known dangers of black-lung disease and cave-ins were now limited with the surface mining method (Bozzi 116). However, surface mining came with it’s own problems, a lot of them being more serious and irreversible than underground mining (Allen 182). This method of surface mining was the spark that created the trend of mountaintop removal (Bozzi 117). Mountaintop removal is the complete destruction of the mountain peak in order to reach coal

Open pit mining is used when a resource is spread out in a rock formation. An enormous hole is dug, and the source is then removed. Open Pit mining is generally used for mining for gold, diamonds, coal, copper and other resources. This method consumes a large amount of habitat that becomes lost. Once mining is completed the pit will generally fill up with water.

Coal mining, in particular, strip mining has become the latest casualty of the growing green movement in the United States. What is strip mining? Encyclopædia Britannica Online defines strip mining as the removal of vegetation, soil, and rock above a layer of coal, followed by the removal of the coal itself (“strip”). Most Americans don’t realize the impact this material of biological origin that can be used as a source of energy (“fossil”), or fossil fuel, has on their everyday lives or the nation’s economy. According to the U.S. Energy Information Administration, the mining industry directly employs some fifty thousand Americans with nearly half that number working in the more specific field of strip mining, or mountain top removal

In order to get ore, the first step is to use explosions to blast the mountains since ore is found in the sedimentary rocks. The ore that has been crushed is put in piles in massive heaps that is then sprinkled with a dilute cyanide solution that penetrates through the pile and bonds with the flecks of gold. The cyanide solution with gold will drain into a staging reservoir. Afterwards the gold cyanide solution will be mixed with carbon making the gold particles bond. Then it will passed towards

Huntley and Avondale Collieries are existing underground mines in the Illawarra coal fields of New South Wales. Both mines are on care and maintenance at present but with an improved financial outlook, the existing infrastructure and the location of the mines in relation existing coal mining infrastructure, an opportunity to reopen the mines is available. A financial model for the reopening of the mines based on provided economic conditions, historical

Surface mining is the coal mining process that accounts for around 60% of the United States’ coal. It tends to be very efficient, with a single worker recovering up to 30 to 40 tons of coal in a day. To begin surface mining coal, a drill must

In our days, mining for resources is inevitable. The resources we need are valuable in everyday life. Such resources mined up are coal, copper, gold, silver, and sand. However, mining poses environmental risks that can degrade the quality of soil and water, which can end up effecting us humans if not taken care of and many of the damages are irreversible once they have occurred.

According to the Mining Intelligence Database, the mining sector employs over one million people and spends over R78 billion in wages and salaries (The Role of Mining in the South African Economy, 2015), and importantly, it is one of the few sector that employs unskilled and semi-skilled people.

Surface mining process include the excavation of overburden including the profitable topsoil and regular vegetation has spread to meet the mineral ores (singh, et al. 2010). These activities are connected with destructive impact to neighborhood. Proper planning needs to be done in mining since it is a short term environmental activity with long term hazards. There are several measures which can be implemented to prevent the harmful effects of mining. Mining exercise are completed in different stages, each
