Oyu Tolgoi - Rio Tinto
Block caving is technically complex, but it is also one of the safest and most cost-effective methods of mining ore from deep below the ground as it uses the force of gravity. Put simply, a void is created under the ore body, which then collapses gradually under its own weight.

Characterization and analysis of discontinuous
While block caving presents an economic means to develop lower grade ore deposits, it often leads to significant ground deformations threatening the safety of overlying mine infrastructure. For guidance on relationships between caving depth and surface subsidence, a comprehensive cave mining database was developed and the database clearly shows caving-induced surface deformations tend to be ...

2021-3-19 At the same time, the caving process gradually propagates upward and further into the orebody. Often, overly large fragments can block an extraction draw point. The culprit can be a single boulder or a stringed arch of smaller boulders. These blockages are referred to, by block-caving miners, as ‘hang-ups’,” Forefront said.
