ELONGATED CUMULATIVE CHARGE FOR CONTOUR INITIATION

摘要

This utility model relates to mining. Elongated cumulative charge for contour initiation comprises of two sensible charges of explosive substance, striker element and filling. To decrease labor consumption of formation of the charge, charges that are sensible are formed through filling with explosive substance two flexible shells with diameters of those equal to (0.55-0.6) of the diameter of the well.
