Differences between underground mining and open pit

As can be seen, no one chooses to exploit an open or underground pit, but the conditions of nature that concentrate the metals in one way or another.

2. Mining Methods Copper

Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface. Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this.
