摘要
用三轴SHPB(SplitHopkinsonPressreBar)高速冲击试验机对含有4种裂隙类型的石英磁铁矿进行高速冲击试验,用筛分法确定冲击试验后矿岩破碎块度组成,分析裂隙对矿岩破碎的影响,建立高应变率下岩石破碎块度的分布规律.
Using high speed impacting SHPB apparatus, four types of crak quartz magnetitewere tested. Using riddling method rock block degree after high speed impact was defined, an effectof crack to broken rock was analysed, and distribution regulation of block degree of broken rock under high strain rate was established.
