Olympic Dam is made up ofundergroundand surface operations and operates a fully integrated processing facility from ore to metal. Theunderground mineis made up of more than 450 kilometres ofundergroundroads and tunnels. Ore minedundergroundis hauled by an automated train system to crushing, storage and ore hoisting facilities.

Iron,copper, nickel, and goldmines; Deposits where both the ore and rock are breakable; It is widely believed that surfaceminingis more productive than mostunderground miningmethods, with the exception of block caving, which has a comparable rate of productivity.

Underground miningis used when thecopper oreis not near the earth's surface.Minersdig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this.Miningthen follows the vein of ore and theunderground minedevelops.

Step 1. Ore is taken out of the ground. Holes are drilled in the ground (if it’s an open-pitmine) or in the rock-face (if it’s anunderground mine), and explosives are placed in them to blast it open.The resulting explosions leave huge quantities ofcopper-bearing rock – also known as ore.

Mining. Although largecopperdeposits are mined by open-cut methods in many of the major producing countries, most of thecopperore produced in Australia comes fromunderground mines. The traditional method used at mostminesinvolves the ore being broken and brought to the surface for crushing.
