which type of mining extracted shallow ore deposits

7 Different Types of Mining Processes – NewsMag

2020-3-12  Underground mining can be used for minerals in more shallow seams, but is more often used for deeper deposits. In order to access the minerals underneath, blasting is done. Blasting is an key part of surface mining, as it helps to prepare the terrain for mining. The rocks are broken up using explosives, and then cleared away using machinery.
