Blasting Impact Simulation Test and Fragmentation Distribution Characteristics in an Open-Pit Mine
Based on the split Hopkinson pressure bar (SHPB) test system, dynamic impact tests of coal specimens under different impact pressures were carried out to study the relationship between the impact load and the size of crushed lump coal. Based on the theory of stress wave attenuation, the relationship...
