A series of uniaxial compression tests were performed on gypsum specimens with preexisting fractures to study the failure mechanism and rock bridges in fractured masses. The coalescence two parallel offset was investigated by monitoring process fracture initiation propagation a video camera. showed that inclined can coalesce shear and/or tensile under load. path mainly depend relative position fractures. For instance, when are coplanar or slightly offset, is generated failure; they...
Large diameter boreholes drilled to a depth of 1000–2000 m are currently investigated in Australia as potential solution for waste emplacement and long-term containment long-lived intermediate-level radioactive (ILW). Different potentially suitable types host rocks considered, including granite, shale salt. This study is aimed at assessing the risk borehole instability large deep shale. The investigation conducted with numerical simulations using CSIRO-developed modelling tools FRACOD...
The authors investigate the failure modes surrounding over-stressed tunnels in rock. Three lines of investigation are employed: three-dimensional (3D) models bored under 3D stress, two-dimensional (2D) numerical simulations 1000 m and 2000 deep using FRACOD, both intact rock masses with one or two joint sets, finally, observations TBM (tunnel boring machine) hard medium massive rocks. reason for 'stress-induced' to initiate, when assumed maximum tangential stress is approximately (0.4–0.5)σc...
In this paper, the Mohr-Coulomb shear strength criterion is modified by mobilising cohesion and internal friction angle with normal stress, in order to capture nonlinearity critical state concept for intact rocks reported literature. The mathematical expression same as classical form, but terms of depend on stress now, leading a nonlinear relationship between stress. It covers both tension compression regions different expressions angle. strengths from two join continuously at transition...
Based on the movement characteristics of overlying strata with gangue backfilling, compression test is designed. The deformation characterristics obtained based different Talbot index. has a logarithmic growth trend, including sharp stage, linear rheological and resistance to changes in stages. more advantageous gradation index control surface subsidence. On basis similarity simulation roof failure evolution supporting force are analyzed. In early stage beam structure damage directly occurs...
HYDROCK method aims to store thermal energy in the rock mass using hydraulically propagated fracture planes. The hydraulic fractures can interact with pre-existing natural resulting a complex network, which influence storage performance. This study investigates interactions between and mechanics approach. new functionality of modelling code FRACOD that enables crossing driven by is presented. A series two-dimensional numerical models prepared simulate interaction at different approach angles...
Water inrush in underground mines is a major safety threat for mining personnel, and it can also cause damage to equipment result severe production losses. be attributed the coalescence of rock fractures formation water channel mass due interaction fractures, hydraulic flow, stress field. Hence, predicting fracturing process key investigating mechanisms safe mining. A new coupling method designed FRACOD investigate disaster (known as “Luotuoshan accident”) which occurred China 2010 32 people...
