A microexplosion technique for modeling large-scale ejection explosions

Based on the theory of approximate similarity of soil-ejection underground explosions, a technique for laboratory modeling of this phenomenon by microexplosions has been developed. This paper describes the experimental setup and reports some results obtained from experiments on selection of a soil simulator and from experiments on elucidation of the atmospheric-pressure role with varied scales of the phenomenon. The results are interpreted by comparing them with full-scale explosions and theoretical data.
