, 2020 ABSTRACT—Intact rock specimens are routinely tested in the laboratory for uniaxial compressive strength (UCS) which is an important design parameter in rock engineering. However, laboratory measurement is always expensive and time consuming and is generally not available as part of the small projects.

IOP Conference Series: Earth and Environmental Science, 2018 To achieve the set objectives, an analysis of uniaxial compressive strength and blasting geometry was used in five different rock types. Blasting is categorized successfully if the blasted material size distribution is ≤45 cm above 85%. With twenty-two times of blasting in five rock types, analyzed fragmentation distributions

Journal of Applied Mathematics and Physics, 2014 Occasionally, in complex inherent characteristics of certain rocks, especially anisotropic rocks it may be difficult to measure the uniaxial compressive strength UCS. However, the use of empirical relationships to evaluate the UCS of rock can be more practical and economical.

Relationship between Texture and Uniaxial Compressive Strength of Rocks [PDF]
, 2017 Uniaxial compressive strength (UCS) is one of the most important parameters of rocks that is routinely used in rock engineering designs. This parameter is influenced greatly by textural properties of rocks; hence it is possible to estimate it from ...

Application of Geostatistical Modelling to Study the Exploration Adequacy of Uniaxial Compressive Strength of Intact Rock alongthe Behesht-Abad Tunnel Route [PDF]
International Journal of Mining and Geo-Engineering, 2014 Uniaxial compressive strength (UCS) is one of the most significant factors on the stability of underground excavation projects. Most of the time, this factor can be obtained by exploratory boreholes evaluation.
