| Abstract: | Block caving is a productive method of mining without drilling and blasting,whose output of ore is determined by the caving process of orebody.Therefore a method to predict the caving of orebody using the priniciple of crack growing rate was developed.With the method the orebody caving rate of Tongkuangyu copper mine in China has been predicted. |
