Sneak Peek #7 - OPEN-PIT MINING
OPEN-PIT MINING is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This method is characterized by a high degree of minerals extraction from the depths.
Open-pit mining is divided into several periods:
• Preparatory period: the territory preparing (deforestation, stumping, rivers diversion, field drainage, highways transfer, construction of warehouses and structures);
• Mining and construction period: the construction of capital and split trenches, drainage works, the installation of the main mining, transport and technological equipment;
• Field exploitation period is the longest one. Systematic excavation and movement of rocks are provided with a mountain transport and auxiliary equipment complex. The mechanization ensures the continuity of transport communications from bottoms to offloading points;
• The final period is a disturbed land restoration and returning it for beneficial use.
