Application of Elongated Cumulative Charge Directed to Fracture of Rocks

摘要

In article the mechanism of destruction of materials under the influence of cumulative "knife" is considered. It is described, how the crack in hills under the influence of cumulative "knife" develops. Stretching pressure arising thus are considered cause also their influence on growth of the main crack from top of a crater of a primary crack. Experimental data of change of the sizes of cracks with growth of duration of action of pressure of products of explosion and with increase in its amplitude are resulted.
