... Crustal stress, and especially its orientation, is one of the key parameters in geotechnical mechanics and engineering. Because of the complexity of traditional crustal stress testing methods, especially in deep holes, the determination of crustal stress orientation is difficult, which...

... failure mechanism. Analysis of low rock mass quality zones combined with the jointing orientation may provide an improvement in the assessment of instabilities. The aim of this paper is to develop a rock mass model of an open pit mine under active operation, based on extensive field mapping. Through...

These are the spatial localization of the stope (mining horizon, mining lenses, and central location within the orebody), the mining method, and the orientation of the major structures relative to stope orientation, the global stope drilling pattern and the stand-up...

... The orientations of discontinuity sets and major geological structures greatly influence the stability of an excavation. Excavations should therefore, where possible, be orientated such that major discontinuity sets and structures are considered, allowing the likelihood of rockfalls...

.... The deformation occurred in a manner exactly opposite to what could be expected in terms of the local stress orientation. A conceptual model is developed that involves a process of transpressional simple shear (consistent with the stress model), which causes closure of the tunnel in a direction nearly normal...

... environment in terms of the joint set orientations and characteristics, as well as the likely key block shapes and sizes. A probabilistic analysis was used to compare a range of mining layouts, panel spans and support designs for the defined geotechnical environment. Within the application, a database...
