Cave mining refers to all mining operations where the orebody has caved naturally after undercutting and the caved material is recovered through drawpoints. Caving is the lowest cost underground mining method for large near-vertical orebodies provided that the drawpoint size and the handling facilities are tailored to suit the caved material.
