Block/Panel caving is an underground mining method in which ore blocks or panels are undercut causing the rocks to cave, and thus allowing broken ore to be extracted at drawpoints. Normally, fine material can be present within the ore column related to a previous exploitation level and may be found over or on the side of the ore column.

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.

Dilution is the mixing of ore and waste. El Teniente is a panel caving mine. The nature of block caving is such that some dilution will occur as the stopes fail towards the draw points. At El teniente, there is more dilution in secondary stopes than primary sections (Susaeta, 2008).

1. Introduction. Block caving is a method that is completely based on the principles of caving. This method is based on the assumption that ore fractures and breaks by itself, due to the presence of internal stresses and forces caused by the weight of the ore body and also the downward movement of the broken rocks. 1 The deposit is divided into large blocks, usually square in shape.

Block caving refers to mass mining methods in which the ore body caves naturally after undercutting and the caved ore is recovered through drawpoints. These include block caving, panel caving and its variations. These methods currently have the lowest operational costs and highest productivity in underground mining [1].
