Describing the rock crushing process from fractal point as follows: rock mass broken into subset blocks with finite number and similar shape .Some of these subset blocks has been broken into more subset blocks with similar shape .And each time for repeating this process has produced smaller blocks .According to the probability and similar ratio of rock broken and the volume for different grain size, it can be drawn: Fund: This article is funded by the National Natural Science Foundation of China(rock damage evolution under Hydraulic fracturing and forming mechanism of micro-cracks No. 50974028) 3 0 bD k k R y R −   =     (1) Where: yk--accumulation volume ratio which fragmentation less than or equal to Rk; Db--fractal dimension of broken blocks [1].
The fractal dimension calculation of rock mass damage and fragmentation So far the sieving method is used to calculate the fractal dimension of rock mass damage fragmentation, but a great number of labor power and material resources will be spent.
