Types of Mining and Fracking
by: Taylor Hess and Lydia Fisher
Surface Mining
- This is different from subsurface because we are getting the minerals from the surface of the ground instead of digging underground.
- 3 Types of surface mining are open pit mining, strip, and mountain top removal
pit mining is extraction of minerals by removing an open pit or borrow
strip mining is going surface deep into a rock to access coal
mountain top removal mining is extacting caol from the summit of the mountain
- Picture Below
- A con to the environment is that it often alters the land and rips it of it natural resources and nutrients.
Subsurface Mining
- This is different from surface mining because we are digging underground instead of getting the minerals from the surface.
- 3 Types of subsurface mining are slope, drift, and shaft mining
Slope mining is a shaft digging down into rock to access coal
Drift Mining is a horizantal passgae underground that might intersect with the ground but might not
Shaft mining is when a large verticle tunnel digs down to access oils
- Picture Below
- One effect on the environment is that they create hazardous mine drainage
Fracking
- The price is very high
- There is an increased number of health hazards
- It harms the environment
- It risk humans safety
