Types of Mining and Fracking
By Josh and Kyle
A form of surface mining when useful minerals are found but the material of interest is structurally unsuitable for tunneling so essentially a big hole/pit is dug into the ground.
Effects- Besides environmental land destruction , hard rock mining exposes rock that has lain unexposed for geological eras. When crushed these rocks expose radioactive elements. If not properly contained the toxic liquids can leak into bedrock.
A form of surface mining where the physical mining is done at the summit or summit ridge of a mountain. Explosives are used to remove up to 400 vertical feet of mountain top.
Effects- Land is deforested prior to mining operations, and there is high potential for human health impacts.
How is it done? Upwards of 400 tanker trucks are used to carry water and supplies to the site. It can take anywhere from 1-8 million gallons of water per a job. The water is then mixed with sand and about 40,000 gallons of chemicals which include uranium, methanol, and mercury. The fracking fluid is then pressured down to about 10,000 feet where the natural gas is tapped into. The problem is that only about 30-50% of the fracking fluid is retrieved. The chemicals are then able to contaminate the ground water which is used for communities.
