A New Rock Bolt Design Criterion and Knowlwdge-based Expert System for Stratified Roof
Since its development in the 1920s, bolting has become the most dominant support method in underground construction. However, because of the geological environment, the design process for roof bolt systems is an art rather than a science. To quantify the selection of bolting systems a MSBT (minimum …

Numerical Modeling Methodology for Weak Rock Masses in Nevada gold mines
… are found in highly fractured and faulted host rock with RMR ranging from 10 to 50. Various ground control design issues in weak rock masses are faced by most underground mines operating in Nevada. Numerical models complement field observations, instrumentation techniques, and testing, by …

Assessment of geotechnical considerations for ground control and stability at Nkana Synclinorium copper mine Mopani Plc, Zambia.
… (1973) classification and Hoek, 1994) for rock mass classification. Scanline mapping of geological structures was done to identify joints, bedding planes, schistosity and folds. The mapping was carried out along the crosscuts or tunnel walls at a 1.50m grade line elevation with geological …

High Spatial Resolution Measurement of Tendon Reinforcement in Underground Construction Works
Distributed optical fiber strain sensing is investigated as a technology to enhance the assessment of tendon reinforcement elements that are commonly used in mines and tunnelling projects. Central to this research effort is the application of a particular high spatial resolution Rayleigh optical …
