Abstract
To study the dynamics characteristics of triaxial coal mass under impact load, the triaxial separated hopkinson pressure bar (SHPB) experiment system was built, and the dynamic impact tests were carried out under the random combination of axial static load, confining pressure and impact load. The dynamics characteristics at these conditions were studied. The experimental results showed that there was no compaction stage in the dynamic...
