¿QUÉ ES EL BLOCK CAVING? 🔥 La TÉCNICA Secreta para EXTRAER Miles de TONELADAS de COBRE y ORO ⛏️

How Does Block Caving Revolutionize Mining?

Introduction to Block Caving

  • The transcript introduces block caving, a method of extracting large volumes of mineral from underground without the need for drilling and blasting.
  • It highlights that gravity plays a crucial role in this process, making it efficient and cost-effective for mining operations.

Understanding Block Caving

  • Block caving is defined as a technique based on the controlled collapse of mineral deposits rather than traditional excavation methods.
  • This method allows for the extraction of low-grade minerals at scale, becoming viable when open-pit mining is no longer feasible.

Phases of Block Caving

  • The process begins with constructing several underground levels before extraction can commence:
  • Undercut Level: Initial fracturing occurs here through drilling and blasting.
  • Production Level: Fragmented material is collected and transported to subsequent levels.
  • Crushing Level: Mineral size is reduced for easier transport.
  • Transport Level: Material is moved to the surface via conveyor belts or haulage systems.

Mechanism of Extraction

  • After preparing these levels, a cut is made at the base of the mineral block, causing it to fracture and fall into designated extraction points.
  • This creates a subsidence phenomenon monitored closely to prevent damage to nearby structures.

Global Applications of Block Caving

  • Notable mines utilizing block caving include:
  • Chuquicamata Underground (Chile): Transitioned from an open-pit operation to extend its lifespan significantly.
  • Oyu Tolgoi (Mongolia): A major copper-gold project expanding through block caving techniques.
  • Grasberg Mine (Indonesia): Implemented block caving after closing its open-pit operations.

Challenges in Block Caving

  • Despite its efficiency, block caving faces challenges such as:
  • Subsidence Risks: Progressive sinking can lead to unexpected collapses affecting infrastructure and worker safety.
  • Mineral Dilution: Mixing of waste material with valuable ore reduces purity during extraction processes.

Advantages of Block Caving

  • Key benefits include:
  • Lower operational costs compared to other underground methods.
  • High production rates capable of extracting up to 100,000 tons per day.
  • Enhanced worker safety due to remote extraction processes.

Future Prospects for Block Caving

  • As surface mineral reserves deplete, block caving will likely become increasingly vital in modern mining practices. Its ability to adapt will be essential in meeting future challenges.
