Block caving method : mining reddit

In Chile a lot of block caving is done without an open pit phase. Most mines are up on the Andes and in this way you just make a semi horizontal tunnel to the base of the ore, normally from the side of the mountain that has the ore, and then you use block caving to make it fall to the tunnel, that normally has a big rail with huge wagons to get the material.

Block caving: A new mining method arises Geoengineer

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.

The method is illustrated in Fig. 7. After the bottom of the block, or panel, is cut up into pillars by drifts and cross drifts, the pillars are robbed, and then the remaining stumps are blasted out with one large blast.
