The Main Types of Mining and their Differences
Unlike underground mining, surface mining does not require deep shafts. Instead, it involves removing the overburden, the material covering the coal seam/ore body. This overburden can consist of soil, rocks, or any type of ecosystem. Surface mining is cost-effective for extracting lower-grade metal ores and industrial minerals near the Earth's ...
