| Abstract: | Based on the stress analysis of filling body,it was pointed out that reducing the destructive function of blasting on the filling body is one of the technical keys in ore pillar extraction.In view of the various destructive ways of blasting,correspondent countermeasures which included the decision on correct blasting scheme,the selection of rational blasting parameters and the adoption of practically feasible protection measures were recommended.When put into practice,they achieved good effects so as to provide a technical guarantee for the overall application of high bench large diameter deep hole mining method in Anqing Copper Mine. |
