Compressive Strength Of Granite Rock

The strength standard of rock under compression and tension, where s is the principal stress, the rock compressive strength 3 is the secondary principal stress, C is the uniaxial compressive strength UCS, M is the material related parameters, but the test results of cylindrical rock samples compressed under CP = 23 show that there are many forces.

Comparison of UCS to Bond Work Indices

Comparison of UCS to Bond Work Indices Alex Doll, Alex G Doll Consulting Ltd, Edmonton, Canada Derek Barratt, DJB Consultants Inc, North Vancouver, Canada Ken Wood, Fluor Mining & Minerals, Vancouver, Canada Abstract Unconfined Compressive Strength (UCS) is a commonly used rockmass strength measurement used by rock mechanics practitioners.

Unconfined Compressive Strength Test of Rock

2016-9-15 · This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. Unconfined Compressive Strength …

Correlation between Uniaxial Compressive Strength and ...

2008-6-6 · Rock engineers widely use the uniaxial compressive strength (UCS) of rocks in designing surface and underground structures. The procedure for measuring this rock strength has been standardized by both the International Society for Rock Mechanics [1] and American Society for Testing and Materials [2]. The method is time consuming and expensive.

Gyratory Crusher Design

2021-9-2 · Rock crushability index is a useful relationship, analogous to the Bond work index, for determining crushing energy for various crusher feed and products. If it is known what size feed is to be fed to a crusher, one can either predict the crushing energy for a particular crusher product size, or the crusher product size, P80, can be predicted ...

2020-10-13 · The uniaxial unconfined compressive strength (UCS) is an important mechanical property of the rock mass having several implications 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.

2016-4-13 · rock strength. Grain size specifically has a significant influence on rock strength (Akram and Bakar, 2007). Generally, rock strength ranges at Mogalakwena Mine would be classified as high to very high, and fall within a rather narrow range. The relationship between grain size and UCS for various rock types is depicted in Figure 3.

Influence of some rock strength properties on jaw crusher ...

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.

Uniaxial Compressive Strength

Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.
