The Environmental Impact of Mining (Different Mining

May 27, 2020 Open-Pit Mining Open-pit mining, one of the most common forms, is one of the most damaging. Miners hollow out a section of land, digging down to create a workable area and extract valuable raw materials. This method leaves behind large pits in the earth and can contaminate the groundwater with chemicals used in the mining process.

Digging deeper: Mining methods explained Anglo American

Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
