Estimation of Uniaxial Compressive Strength of Coal ...
The uniaxial unconfined compressive strength (UCS) is an important mechanical property of the rock mass having several impliions in planning and de signing both underground and opencast coal mines. UCS is usually determined on core samples obtained fr om exploratory boreholes and tested either in the field or preferably in the laboratory. McNally (1987 and 1990) has the unique .
ASTM D7012
Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique. Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most .

The pointload strength test
· Uniaxial compressive strength has been shown on the same diagram by juxtaposing the two scales using the ratio of uniaxial to pointload strengths given in Fig. 21. The choice of a system for subdividing the pointload scale into 'classes' may now call directly on previous subdivision schemes for uniaxial strength; the report of the Geological Society of London .

compressive strength of talc
· · The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heattreated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength .

Publiions on Uniaxial compressive strength (UCS ...
The uniaxial compressive strength (UCS) of rock is an important parameter required for design and analysis of rock structures, and rock mass classifiion. Uniaxial compression test is the direct method to obtain the UCS values. However, these tests are generally tedious, timeconsuming, expensive, and sometimes impossible to perform due to difficult rock conditions. Therefore, .
