【摘要】 利用一级轻气炮对岩石试件进行冲击损伤实验,采用软回收装置回收样品,并用筛分法确定冲击试验后矿岩破碎块度组成,分析不同动荷载下岩石的不同块度分布,建立动荷载下岩石破碎块度的分布规律,对爆破设计有一定的指导作用。更多还原

【Abstract】 The impact damage experiments for rocks are carried out by the one-stage light-gas gun. The samples are recovered by soft recovering devices and thescreening method is used to determine the rock crushing fragment composition after the impact experiment. The different fragment distribution of rock under different loads is analyzed and the distribution rules of the rock crushing fragment under dynamic load are established, which gives a reference to the blast design.更多还原
