Determining the uniaxial compressive strength of intact rock is primary objective a geomechanical project, and reliable estimate in early phases saves time costs for more sophisticated laboratory tests. The problem knowing which correlations between resistance to compression point load index are reliable, those that cover one or several types (depending on type statistical adjustment). In this ...

The geomechanical classification SMR (Slope Mass Rating) enables the preliminary assessment of the susceptibility of rock slopes to failure. The SMR index is obtained from Bieniawski’s basic RMR (Rock Mass Rating) through an “adjustment factor” and an “excavation factor”. Since its appearance in 1985, this classification has been used for appraisals and preliminary studies in many countries. Th...

This paper presents the results of a numerical analysis impact rock mass geomechanical parameters on stability preparatory headings located within Legnica-Glogow Copper District. The shows calculations prepared for driven in two types with different strength and deformation parameters, which allow illustrating their influence safety mining performed underground copper ore mines. Numerical model...

Abstract In the present work, fully coupled dynamic thermo-hydro-mechanical (THM) model was employed to investigate advantage and disadvantages of supercritical CO2 (SCCO2) over water as geofluids. Low-temperature zone found in both SCCO2-enhanced geothermal system (EGS) water-EGS systems, but spatial expansion is higher water-EGS. Although, SCCO2 into rock matrix will help geo-sequestration, s...
