The jointed structure distribution of rock mass is simulated by Monte Carlo method. Based on fracture mechanics, original extension and the stopping of crack of the jointed rock mass is analysed,the extended angle and the extended length of the jointed rock mass by blasting is calculated, and the figure of the jointed rock mass structure after blasting is drawn. It is very important to research into the characteristics of the rock mass after blasting.
