摘　　要：在预算台阶爆破爆炸能利用率的基础上,建立CEFM数模预测高台阶爆破的爆破块度和爆堆形状,预测结果能与实际情况较好地吻合。On the basis of the estimated utilization of explosion energy in bench blasting, CEFM mathematical model was built up to predict the blast fragmentation and muck-pile shape of high-bench blasting, and the results of prediction were able to coincide well with the actual situation.

关 键 词：高台阶爆破 数模 爆炸能利用率 爆破块度 爆堆形状
