摘要
在露天矿溜井降段和新水平开拓的段沟掘进过程中,探索使用一种深孔挤压爆破结合多排孔毫秒微差起爆一次成沟工艺,并取得了成功。
In the process of excavation of chute descending and dropping-level ditch explored in new level in open pit,the technique of one-time trenching using squeeze blasting and split second blasting was exploringly employed,and the result showed that it was a success.
