Analysis of block stability for semi - level caving method with lateral loading (original) (raw)

2013, Mining and Metallurgy Engineering Bor

In the current conditions for global underground mining, with the new ore deposits lying deeper and deeper, with reduced ore grades, the bulk mining is a necessity. Only high production level provides chances for positive economic results of underground mining. The high productive mining methods enable significant reducing of costs per ton of excavated ore. Different variants of block methods belong to this group of bulk mining methods. One of them, named the semi-level caving, is present in this paper, with analysis of its block and drawbells stability.
