Difference between open pit and shaft mining?
Open Pit Mining
Shaft Mining
- Open pit mining is a surface mining technique that involves the removal of rock or minerals from an open pit or borrow.
- This method is used when the minerals or rock are found near the surface of the earth.
- Large scale equipment such as bulldozers, excavators, and trucks are used to remove overburden and extract the ore.
- The ore is then transported to a processing plant for further refinement.
- Open pit mining is usually used for mining metallic ores such as copper, gold, and silver.
- This method is cost-effective and can be used to mine large deposits of minerals.
- However, it can have negative environmental impacts such as deforestation, soil erosion, and pollution of water resources.
Shaft Mining
- Shaft mining is a type of underground mining that involves the excavation of vertical tunnels or shafts to access mineral deposits.
- This method is used when the minerals or rock are found at a deeper depth in the earth.
- Shaft mining involves drilling a vertical or inclined shaft from the surface to the depth where the mineral deposit is located.
- A series of tunnels are then excavated from the shaft to access the ore.
- The ore is then transported to the surface using hoists and conveyors.
- Shaft mining is usually used for mining coal and other minerals such as potash, diamonds, and uranium.
- This method is more expensive than open pit mining but is often used when the mineral deposit is too deep for open pit mining.
- Shaft mining can have negative environmental impacts such as soil compaction, groundwater depletion, and air pollution from diesel engines used in the excavation process.
