Karjäärid

Karjäärid are open-pit mines used for extracting minerals. They are characterized by their large scale and the removal of overlying rock and soil to expose the desired ore. The process typically involves drilling, blasting, and then excavating the rock. The extracted material is then transported for processing. Karjäärid can be found in various geological settings and are a primary source of many raw materials essential for industry and construction.

The environmental impact of karjäärid is a significant consideration. They can alter landscapes, affect water tables, and produce dust and noise. Reclamation efforts are often undertaken after mining operations cease to restore the land to a more natural state or for other beneficial uses. The economic importance of karjäärid lies in their contribution to resource extraction, providing jobs and raw materials that fuel economies worldwide. The design and operation of karjäärid require extensive planning and engineering to ensure safety and efficiency.
