The Dynamic Effect Analysis of Transient Unloading due to Blasting Excavation in Deep and Hard Rock Roadway

Abstract:

The dynamic effect analysis of transient unloading is one of main points to the mechanism of rock fragmentation by blasting. The paper introduces the details of rhe effect of instantaneous unloading to rock fragmentation by blasting. Use the dynamic finite element method to calculate the process of transient unloading of excavation; get some conclusions about transient unloading.
