Paper: How does a caved rock mass behave under confined ...

Abstract: Caving methods rely on gravity to break and transport large amounts of ore and waste. The application of massive underground mining is becoming ever more prevalent, specifically caving mines at deeper levels, mainly due to the depletion of mining reserves. It is thus relevant to study mechanisms that occur at deeper levels.
