Open-pit mining - Wikipedia

To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting each hole lo ion on a map. The information gained through the holes with provide an idea of the vertical extent of the ore& 39;s body.

Copper Mining and Production Processes Explained

Mining. The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.
