Techniques in Underground Mining - ILO Encyclopaedia

The Underground Mine. The underground mine is a factory located in the bedrock inside the earth in which miners work to recover minerals hidden in the rock mass. They drill, charge and blast to access and recover the ore, i.e., rock containing a mix of minerals of which at least one can be processed into a product that can be sold at a profit.

Mine Ventilation Systems
