THE EFFECT OF DYNAMIC PROPERTIES OF ROCK ON BLASTING UNDFR HIGH STRAIN RATE
高应变率下的岩石动载特性对爆破效果的影响

The advanced triaxial Split Hopkinsos Pressure Bar has been used to study the dynamic behavior of three kind of magnetites, one granite, ont limestone(coarse grained) and one sandstone at high strain rate. On the basis of test, the effect of dynamic properties of rock on blasting is further discussed under high strain rate.
