⭐⭐⭐⭐⭐
score is between 0 and 5
Block caving mining method is a mass mining technique used for extracting large underground ore bodies through undercutting the rock mass to cause it to collapse and be drawn off into a collection area.
Key Features
- Mass mining technique
- Undercutting of rock mass
- Collapse of ore body
- Collection area for extracted material
Pros
- Efficient extraction of large underground ore bodies
- Cost-effective method for mining low-grade deposits
- Minimizes environmental impact compared to other mining methods
Cons
- Requires careful planning and monitoring to prevent cave-ins
- Long-term stability concerns for surrounding rock mass
- Potential for ground surface subsidence above mined area
