Underground Support Principles and Rock Mechanical Challenges in Deep Mining

Ground support aims to create a stable underground space that is excavated in rock mass conditions. The speech will cover the following contents: disturbance and potential instabilities caused by an excavation, static ground support principles, challenges of rock mechanics in deep mining, dynamic ground support and the performances of the conventional rock bolts and the relatively new dynamic yield rock bolts.
