The Sublevel Caving Method in Mining is a highly productive underground mining technique used for large ore bodies. The Sublevel Caving Method in Mining is known for its ability to handle weak ore and host rock conditions efficiently. In modern mining, the Sublevel Caving Method in Mining is widely used for bulk extraction. At MiningGyan, the Sublevel Caving Method in Mining is explained in a simple and practical way for better understanding.
Sublevel Caving Method in Mining – Definition and Concept
The Sublevel Caving Method in Mining is an underground mining method where ore is extracted from multiple sublevels and the overlying rock is allowed to cave. The Sublevel Caving Method in Mining works by breaking ore in slices and letting gravity assist the flow. In the Sublevel Caving Method in Mining, no permanent support is left in the mined-out area. This makes the Sublevel Caving Method in Mining suitable for large and weak ore bodies.

Basic Terms in Sublevel Caving Method in Mining
| Term | Meaning |
|---|---|
| Sublevel | Horizontal working level in ore body |
| Caving | Controlled collapse of rock |
| Drawpoint | Point where ore is collected |
| Ore Flow | Movement of broken ore by gravity |
Sublevel Caving Method in Mining – Working Principle
The Sublevel Caving Method in Mining works on the principle of gravity flow and controlled caving. The Sublevel Caving Method in Mining involves drilling and blasting ore from sublevels. In the Sublevel Caving Method in Mining, broken ore flows downward to drawpoints. This makes the Sublevel Caving Method in Mining efficient for continuous production.
