孔内正反向传爆的作用机理周同龄李玉寿（中国矿业大学徐州市２２１００８）１有限柱状药包正反向传爆的应力场１．１单自由面应力场分布自由面对爆破的影响是显著的，单自由面时正反向起爆方式下，有限柱状药包形成的应力场与爆轰波速Ｄ和介质弹性纵波速Ｃ之比有关。就一...
It is analysisd that the stress field of columnar charges in the paper,which is formed at one or two free face.Also,it is imquired that the action mechamism of transmiting explosive wave with positive or negative direction in holes.
