UCS (UNIAXIAL COMPRESSIVE STRENGTH) Predicting the strength and brittleness of rocks from a crushability index FRENCH ABRASIVENESS TEST The Abrasivity Coefficient (ABR) is defined as the ratio of the is given in grams per ton and varies between 0 to over 2000, depending on whether the rock is respectively little or highly abrasive.

HoekBrown equations. Hoek and Brown compiled extensive data on a variety of rock types and produced relationships that are simple and can be developed into forms amenable to welllog analysis. A primary feature of this failure criterion is a relation between the maximum and minimum stresses when both are normalized by the uniaxial compressive strength

the appropriate equipment needed to rip a specified rock. The primary rock properties determining the index are the joint alteration, joint roughness, joint orientation, compressive strength, and size of individual rock blocks. The ripability index was adapted for the analysis of soil erosion and described as a

Impact Crusher. Impact crusher is suitable for materials whose compressive strength is under 350Mpa, and particle size is less than 500mm. With end products in cubic shape, the impact crusher is widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and building materials and so on.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

dynamic and static rock properties most critical to the licensing applications are the compression and shear wave velocities, static and dynamic moduli, uniaxial compressive strength (UCS), and density. Since suspension PS logging provides a specific measure of compression (primary or P) and shear

Mechanical properties of rock The mechanical properties of rock such as density, Young's modulus and uniaxial compressive strength (UCS) influence the rock mass blastability and can be determined from laboratory tests. The samples for conducting these tests are usually obtained from the blast muckpiles.
