Based on the law of the spatial distribution, using Monte Carlo technology to simulate joint system, and using three-dimensional solid cutting techniques to build a new rock mass fragmentation prediction model of block three-dimensional interception model. Based on consideration in the joint continuity and the mechanical properties of rock mass, the model simulated the spatial distribution of structure planes according to statistical principles, and predicted rock mass fragmentation using structure planes to cut model prototype and ultimately formed a block muster consisting of cutting blocks. Then, according to a new method of the block shape classification, the distribution statistic rule of internal entities rock block, which are cut out by the structure planes, size and shape are studied. The simulation results show that the fragments with equivalent size of more than 1.65 m account for 40 per cent and those more than 1.26 m account for 59.85 per cent of the total fragment volume.
