Raw material of various sizes are brought to the primary crusher by rear-dump haul units, or carried by a wheel front-end loader. Primary crushing reduces excavated rock to a more manageable size. There are different types of primary secondary and tertiary crushers including jaw crushers, gyratory crushers, impact crushers, and autogenous crushers.

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. Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining.
