Moving towards deep underground mineral resources
Underground mining has historically occurred in surface and near-surface (shallow) mineral deposits. While no universal definition of deep underground mining exists, humanity's need for non-renewable natural resources has inevitably pushed the boundaries of possibility in terms of environmental and technological constraints.
Underground Mining
Underground mining is more complex and more expensive than open-pit mining. Where removing the overburden would be too costly or ineffective to reach the ore, the decision is made to go underground. After open-pit mining is complete, valuable ore can be mined through underground mining methods.
A Guide to the Four Main Methods of Mining
Each of the four mining methods are explained below. Underground Mining. Relatively costly and frequently used to get to deeper deposits, underground mining involves digging down into the …
