The Block Caving Method in Mining is known for its low operating cost and high production capacity. In modern mining, the Block Caving Method in Mining is widely applied to massive ore bodies. At MiningGyan, the Block Caving Method in Mining is explained in a simple and practical way for students and professionals.
Block Caving Method in Mining – Definition and Concept
The Block Caving Method in Mining is an underground mining technique where a large block of ore is undercut and allowed to collapse under its own weight. The Block Caving Method in Mining uses gravity to break and move ore downward. In the Block Caving Method in Mining, no artificial support is used in the caved zone. This makes the Block Caving Method in Mining suitable for massive and low-grade ore bodies.
Basic Terms in Block Caving Method in Mining
| Term | Meaning |
|---|---|
| Undercutting | Removing base support of ore |
| Caving | Natural collapse of ore |
| Drawpoint | Location where ore is collected |
| Ore Flow | Gravity movement of ore |
Block Caving Method in Mining – Working Principle
The Block Caving Method in Mining works on the principle of gravity-assisted caving. The Block Caving Method in Mining begins by undercutting the ore body to initiate collapse. In the Block Caving Method in Mining, broken ore flows downward to drawpoints. This makes the Block Caving Method in Mining highly efficient for continuous large-scale production.
