Unconfined Compressive Strength (UCS) is a commonly used rockmass strength measurement used by rock mechanics practitioners. This paper examines potential relationships between UCS and Bond Work Index values (crushing, rod mill and ball mill). Data from 11 mines located around the world is analysed for correlations between UCS and various Wi ...

The results of the strength parameters of each sample were correlated with the crushing time and the grain size distribution of the rock types. The results of the strength tests show that granite has the highest mean value of 101.67 MPa for Unconfined Compressive Strength (UCS) test, 6.43 MPa for Point Load test while dolomite has the least ...

Unconfined compressive strength tests apply compression to a rock sample until it fails. The "plane of failure" in a rock typically occurs along a structural weakness rather than breaking along grain boundaries. These joints and shear planes that control the failure of rock in a UCS test play a minimal.

Abstract: The influence of rock strength properties on Jaw Crusher performance was carried out to determine the effect of rock strength on crushing time and grain size distribution of the rocks. Investigation was conducted on four different rock samples namely marble, dolomite, limestone and granite which were representatively selected from fragmented lumps in quarries.

Strength is considered in terms of compressive strength, tensile strength, and shear strength, namely the limit states of compressive stress, tensile stress and shear stress, respectively[2]. According to Reference [3], the effect of dynamic loading is probably the most important practical part of the strength of materials, especially the problem of fatigue.
