Computer Simulation To Predict Ore Loss And Dilution In Caving Mining Methods

The main feature of caving methods is to draw ore from the overlying waste rock. Research on the movements of ore and waste plays a very important part in reducing ore loss and dilution and raising the economic benefits. This paper gives the basic theory of computer simulation of ore-draw, exposses the physical significance of mathematical model, puts forword a new formula of similarity characteristic value, brings forth a method of adjusting similarity, introduces the major functions of the simulation program and describes the ore draw control and stope parameter selection through computer simulation.
