Modeling and application of civil explosives in different types of soil

Abstract. Civil or mining explosives have wide application in rock excavation and mining, but in the case of soils, their application is limited to some special blasting operations such as ground improvement. The three main applications of explosives in ground improvement are: soil compaction, mass excavation, and in situ pile creation. The suitability of explosives for each of these applications strongly depends upon the explosive properties and soil properties. The paper presents results of research of the soil compaction by civil explosives and modeling of that process using AUTODYN software. Explosive compaction has been performed in different type of soil. The calculated results from AUTODYN and the results obtained from in situ explosive compaction are compared and presented.
