Open pit mining pros cons
When a desired mineral or rock is near the surface, companies typically opt for open-pit mining due to its lower costs and increased efficiency. Open-pits are typically dug in tiers and with angled walls to cut-down the risk of collapse or falling rocks. These holes can be tens of miles wide and thousands of feet deep. Generally these pits

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 location on a map. The information gained through the holes with provide an idea of the vertical extent of the ore's body.
