The unconfined compressive strength UCS of rocks is a crucial factor in geotechnical engineering assuming a central role in various civil engineering undertakings including tunnel construction mining operations and the design of foundations The precision in forecasting UCS holds paramount importance in upholding the security and steadfastness of
Uniaxial compressive strength UCS is an important mechanical parameter for rock classification rock mass engineering design and rock mass stability analysis and it can also be used to assess rock material strength in Rock Mass Rating RMR 1 Conventionally the UCS of rocks can be determined by the uniaxial compressive tests as suggested by the
Basalt physical properties such as compressive strength and density are directly linked to their chemistry and constitution; as weathering progresses basalts gradually become weaker and
Basalt is among the most used rocks as aggregate ballast ornamental stone and for other construction purposes Therefore the uniaxial compressive strength UCS and elasticity modulus Ei of intact rock are required to be known for several purposes For this reason the purpose of the present study is to develop various non linear prediction Model s for
Thomson et al 2013 used the RAT data for inferring the compressive strength of Gusev fragments based on a laboratory calibration method that used the relationship between the weathering and

[1] Each Mars Exploration Rover carries a Rock Abrasion Tool RAT whose intended use was to abrade the outer surfaces of rocks to expose more pristine material Motor currents drawn by the RAT motors are related to the strength and hardness of rock surfaces undergoing abrasion and these data can be used to infer more about a target rock s physical
Abstract To predict uniaxial compressive strength using the indirect techniques of the Schmidt hammer rebound number N and Point Load Index PLI it is required to have valid empirical equations based on rock types This study is an attempt to address this issue by developing a model that is valid for various rock types Three models linear power and
