Zhang used Hertzian contact theory to calculate critical crushing strengths of quartz sands and found that porosity and grain radius combine to determine strength (Fig. 8). Fig. 8 – Critical or crushing pressure as a function of the grain size-grain radius product (after Zhang [13] ).

This new theory worked from rock breakage principles to design blasts and became the prominent blast design of the early 1900s. Shear theory, while now understood to be wrong in many cases, was one of the early theories about how a bench broke and designing the “line of resistance,” which, today, is called the burden.

8.4 THEORY OF STRENGTH Several theories of strength have been applied to soils and rocks but the most widely used is the Mohr-Coloumb theory. This is based upon a combination of the Mohr theory of strength and the Coulomb equation. Referring to Fig. 8.10 the stresses on the failure plane of a material are related by means of a general expression.

It is suggested that the plucking mechanism, a necessary complement to abrasion and crushing in eroding a rock bed, will be co-extensive with these processes. Plucking alone is necessary to erode unlithified sediments. The theory also explains the forms of glaciated U-shaped valleys, cirques, valley steps, over deepened basins and fjords.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand 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.

2 WEAR THEORY Abrasive wear is among the most common wear forms encountered when cutting coal using coal shearers. As the shearer cuts the coal, the pick comes in direct contact with the coal rock, which causes abrasive wear. Thus, it is evident that the stone in the coal rock damages the pick. Depending on the friction forms and the contact stress

Yet, such processes as rock crushing or cracks system evolution are of great importance in drilling (see review by Mishnaevsky Jr 1995b). For example, the energy consumption in drilling is determined by the rock crushing to a large extent; about 80 % of the loading energy is spent just for it.
