In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing

Rotating cutting drilling is a common method for drilling in softer materials such as sand, clay and soft rock. A drag bit is used instead of a normal drill bit. This bit has 2-4 wings with carbide tips that cut up the material by pressure and rotation. Rotating crushing drilling. Rotating crushing

5.2 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 underground rock
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation.It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction.The result of rock blasting is often known as a rock
Jan 08, 2012 However, as new fine particles are created by crushing and attrition and since moisture content is reduced by evaporation, this suppressive effect diminishes in later stages. The type of rock processed is also important. Soft rock
In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Furthermore, if a rock mass is cut by directional joint sets,the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock
It has been found that a rock core will split along a diameter when loaded on its side in a compression machine. This is the basis of the Brazilian test which is an indirect method of measuring tensile strength. A rock
