In many site investigation phases of civil and mining engineering projects, the tensile
strength of the rocks is one of the most significant parameters that must be identified. This …

Mechanical characterization of hydrothermally altered rocks from geothermal reservoirs will
lead to an improved understanding of rock mechanics in a geothermal environment. To …

Imaging the wave velocity field surrounding a borehole while drilling is a promising and
urgently needed approach for extending the exploration range of the borehole point. This …

This paper surveys the field of measurement-while-drilling (MWD) technology for
smalldiameter drilling machines. Using this technology, mechanical data (eg, torque, thrust …

The evaluation of geotechnical parameters of geo-materials are essential part of every
geotechnical project. But sometimes, it is not possible to determine the all required …

The rock uniaxial compressive strength (UCS) is the basic parameter for support designs in
underground engineering. In particular, the rock UCS should be obtained rapidly for …

One of the most important products of the majority of tools, processes and, phenomena in
mining engineering and earth sciences are high-frequency elastic waves, often referred to …

Rocks are natural geo-materials, whose properties are affected by many spatially-varying
factors, such as the properties of their parent materials, weathering processes, and …

Rock tensile strength (TS) is an essential parameter for designing structures in rock-based
projects such as tunnels, dams, and foundations. During the preliminary phase of …

Unconfined compressive strength (UCS) of rocks is one of the most important parameters in
rock engineering, engineering geology, and mining projects. In the laboratory determination …
