Description	As fracture happens because of an external stress system, rock is divided into smaller fragments with arbitrary shapes, and it also absorbs a certain amount of energy. The exploration of energy-size reduction dates back to the late-19th century. Many theories (such as the new surface hypothesis, the similarity hypothesis, and the third comminution theory) were proposed to solve engineering problems such as crushing, grinding, and blasting. These theories are all related to the distribution function of fragmentation which is commonly used in mining, geology, and mineral processing. A wide range of fragmentation phenomena have been discussed by Hartmann (1969). Fragmentation plays an important role in a variety of mining and geological phenomena. Donnison & Sugden (1984) have found that fragmentation controls the determination of the size- frequency relationship of asteroids and meteorites. A variety of statistical relations has been used to correlate data on the size distribution of fragments, and a simple power-law relationship is often used. Recently, Turcotte (1986a) and Zhao et al. (1990) have described these fragmentational distributions with power-law relationships in terms of the fractal theory. We have also proved this description by obtaining much experimental data on rock failure in the laboratory (Xie & Gao, 1991). Book Name: Fractals in Rock Mechanics
