Surface Mining and Subsurface Mining
Surface mining and Subsurface mining are the two different types of mining...
surface mining is when soil and rock overlying the mineral deposit are removed. Strip mining, open-pit mining and mountaintop removal mining are all examples of surface mining.
Subsurface mining is extraction of minerals from underground. Subsurface mining is Very dangerous conditions can include collapses, released gases, particulates in the air, low oxygen, and heat.
Types of Mining
Placer
Placer mining when raw materials are put into gravel or sand or on the surface. Water is polluted and also is withdrawn from the streams.
Hardrock
Hardrock Mining is when soild rock is dug into to fine minerals. This causes sinkholes and erosions.
Open Pit
surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. Open pit mining causes water loss in the streams and can also add pollution to the groundwater.
Land drilling vs ocean drilling
Ocean drilling is a mechanical process where a wellbore is drilled below the sea bed. This caused extra poltoluem and causes extra rock layers under the sea bed. Land drilling is used to drill for oil or gas. Land drilling causes pollution in the air and could possibility displace human and animal pollution.
Fracking?
Fracking involves safely tapping shale and other tight-rock formations by drilling a mile or more below the surface before gradually turning horizontal and continuing several thousand feet more. Fracking allows the US to tap for vast oil and natural gas reserves that previously were locked away in shale and other tight-rock formations. fracturing cause loud noises and require bright lights. Industrial equipment, like flare stacks and waste pits, emit smog-forming volatile organic compounds and benzene,
