摘　　要：鞍千铁矿因前期靠帮爆破时没有采用预裂爆破,形成的边坡大都不平整和稳定,给日常生产留下了安全隐患。为了保证采场固定边坡的稳固性,在现场进行预裂爆破试验,从爆破参数、装药结构、起爆方式、起爆网路等方面加以考虑,对靠帮边坡进行处理并取得了良好的效果,为以后靠帮预裂爆破提供指导。Because the pre-split blasting had not been used in early pit slope blasting in Anqian iron mine,the slopes were not smooth and stable,and it brought hidden trouble to the daily production.In order to ensure the stability of the permanent slope,the pre-splitting blasting test was carried out on the spot.The blasting parameters,charge structure,priming way,blasting network and so on were considered to deal with pit slope and good effect was achieved.It provided the guiding basis for the future pre-split blasting against slope.
