Abstract: Methods used to estimate strength and deformability properties of discontinuous rock can be categorized into: (1) The direct testing method; (2) the empirical correlation method; and (3) the analytical decomposition model ...

Abstract: The paper provides a methodology to estimate the spatial variation of potentiometric surfaces, allowing for possible uncertainties such as instrument errors, human errors, and statistical errors. The spatial variation is ...

Abstract: Results of an investigation which is aimed at improving search patterns used in subsurface exploration are presented. Expressions are developed for probability of detection of elliptical targets from various continuous ...

Abstract: Strainburst is the most common type of rockburst in deep excavations, which sometime result in heavy losses. This research studies the feasibility of a conceptualized destressing method for strainburst control. In this ...

Abstract: In general, roughness profiles of rock joints consist of nonstationary and stationary components. At the simplest level, only one parameter is necessary to quantify nonstationary joint roughness. To capture the nonstationary ...

Abstract: The effect of joint geometry parameters (joint orientation, joint density, and joint size) and joint transmissivity on the hydraulic properties of jointed rock blocks was examined in two dimensions using joint networks ...

Abstract: The fracture tensor is a combined measure of joint geometry parameters. The possible relations between the properties of the fracture tensor and the hydraulic properties of jointed rock including the equivalent continuum ...

Abstract: The effect of joint geometry parameters and the size of jointed rock block on the hydraulic properties of jointed rock, including the equivalent continuum behavior, was investigated through numerical experimentation. The ...

Abstract: To simulate brittle rocks, a mixture of sand, plaster of paris, and water was used as a model material. Thin galvanized sheets were used to create joints in blocks made out of the model material. To investigate the failure ...
