Abstract:

Vietnam's open-pit mines have been exploited deeper and deeper. At the end of exploitation, the bottom of the mine is 300÷400 m lower than the sea level. Mining in the deep layers will face a series of difficulties such as seasonal exploitation, high pit bank, large amount of water mud, limited field size, increasing intensity of exploitation on each layer and the whole shore, conditions. The microclimate changes in an unfavorable direction at the bottom of the mine, etc. On the basis of the analysis of the characteristics of the deep layers, experience in exploiting at home and abroad, the article proposes a number of mining technology solutions. Appropriate exploitation at deep open mines such as: Exploiting convex banks, using transport equipment operating on high slope, water mud treatment technology and deep digging seasonally for safe exploitation to ensure mine output, efficiency and maximum resource recovery.
