Types of Mining
- Surface Mining
- Strip mining
- Open-pit mining
- Placer mining
- Mountaintop removal
- Dredging
- Underground Mining
- Continuous mining
- Longwall mining
- Blast mining
- Shortwall mining
Modern Mining Methods
- Open-cast mining is used for shallow mineral deposits.
- Bord and pillar mining drawbacks:
- Less extraction percentage compared to longwall mining.
- Constant machinery relocation.
- Longwall mining involves continuous extraction of large blocks.
Mining Impact and Techniques
- Majorly mined minerals: coal, iron, bauxite, copper, and gold.
- Environmental impacts are mitigated through improved practices.
- Data mining techniques: classification, clustering, association, prediction, and regression.
ASIC Mining
- Specialized hardware for efficient Bitcoin mining.
- Highest hash rate and power efficiency for Bitcoin.
Ore Extraction Techniques
- Cut-and-fill stopping allows selective recovery of high-grade ore sections.
- Fill material supports walls for the next slice cutting.
Summary
- Surface mining is more prevalent, accounting for 85% of US minerals.
- Underground mining methods include continuous, longwall, blast, and shortwall mining.
- Open-cast mining targets shallow mineral deposits.
- Modern mines focus on mitigating environmental impacts and employ data mining techniques for effective operations.
