... Abstract This paper discusses the purposes of, and the processes involved in, the several types of technical audit and/or review of aspects of rock engineering projects carried out in an international consulting practice. The reviews discussed relate to the investigation, design...

... Abstract The naturally existing fractures in a rock mass induce heterogeneity and anisotropy for its engineering properties, resulting in difficulties for investigation on hydrogeological characteristics of fractured rock masses. Aiming to gain more insight into the difference of permeability...

.... Hence, to examine and analyze the characteristic and reasons of some typical cases, it is important to better understand the structure induced deformation in tunnel and to provide valuable references for enhancing the connection between design, construction and investigation. Reservoir...

... factor that has to be taken into account in geotechnical investigations. These information make the basis for realistic design of underground and surface projects such as tunnel, mines etc. Roughness has various features depending on the type of specimens, size and observation scale. In some cases...

... tunneling, and a proper geomechanical characterization is imperative. However, investigating the overall-properties is currently a challenging task, originating from difficulties in sample acquisition, sample preparation and laboratory testing. In order to gain insight into the overall mechanical...

... Abstract Instability in production blast holes causes poor fragmentation, lower ore recovery, delay in production and higher costs in crushing and grinding. In this investigation, three large ore bodies named Alliansen, Fabian and Vi-Riwere selected. Avideo camera was used for mapping...
