BOSTON (CBS) - For first responders, knowing the characteristics of different kinds of explosives can lead them to the bomber, which is why there was a special training session held Tuesday. With the five year anniversary of the Boston Marathon Bombings just a few days away, the importance of...
This study aims to characterize the alteration in mineral grindability due to applying different types of explosives in the blasting operation. For this purpose, several experimental blastings have been carried out on some granite blocks using three kinds of explosives; ANFO, Emulite and Pentolite. ...

If explosives are used, vibrations will cause the roof of the mine 【3】 (collapse). Rescue workers are therefore drilling a hole on the north side of the mine. They intend to bring the men up in 【4】 special capsule. 【5】 there had not been a hard layer of rock beneath the soil...
7. The explosives used in the experiment were respectively detonated at the center point. The liner and explosive were bonded by a certain ratio of shellac paint. The bonded shaped charge structure is shown in Fig. 8. Figure 7 Explosive of jet forming experiment. Full size image Figure 8 ...
polymer bonded explosivesmechanical propertiesmolecular dynamicsThe mechanical properties of PBXs composed of the well-known insensitive explosive TATB (1,3,5-Triamino-2,4,6-trinitrobenzene) crystal and four kinds of typical fluorine-polymers, i.e. poly (vinylidene difluoride) (PVDF), polychloro...
The study of high-energy and low-vulnerability propellants is important for the power performance and safety of solid propellant rocket motors. The modified split Hopkinson pressure bar (SHPB) tests are performed on two kinds of propellant with different crosslinking density to study the dynamic mech...
