摘要
以首钢硼铁矿中深孔爆破为例,论述了大块产生的部位和原因,并提出了一些防治措施,对露天矿山中深孔爆破控制大块的产生具有一定的借鉴意义。
Taking the medium-length hole blasting in paigeite mine of Shougang Mining Corporation for example,this paper discusses the locations and reasons for producing the large blocks,and put forward some controlling measures,for the open-pit mines have a certain reference significance.
