2022-5-20 The two major categories of modern mining include surface mining and underground mining. In surface mining, the ground is blasted so that ores near Earth’s surface can be removed and carried to refineries to extract the minerals. Surface mining can be destructive to the surrounding landscape, leaving huge open pits behind.
