MINING

Mining means extracting stones and minerals, such as coal, from under the ground.

Miners dig into the soil to reach these natural resources. 

There are two types of mining:

Open mining. When minerals are near the surface of the earth, miners dig quarries. These are large, open holes on the land.

Underground mining. When minerals are deep under the earth, miners dig underground mines. These are deep tunnels below the surface. They have lifts to go up and down the mine.
