【摘要】 为获得符合坝工要求的填筑材料,需要对石料开采进行试验研究.通过综合试验确定了爆破参数,并分析爆破参数的变化对开采料块度级配的影响,进而改变参数进行试验,且把获得的石料进行筛分,通过分析计算得到适合于工程需要块度模型,指导石料开采施工.更多还原

【Abstract】 In order to gain the material fitting the requirement in damming,it is necessary to study the rock material exploitation. The means is the explosive test. And the explosive parameter is established in the test. How the explosive parameter affects the exploitation grading is analyzed. The variant explosive parameter is tested further. The grading model is gained in screening out the explosive work rock,which guides the construction of the explosive work rock.更多还原
