What Are the 5 Methods of Mining?

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.
