DEEP-HOLE CHARGE Russian patent published in 2004 - IPC

Abstract RU 2229682 C2

FIELD: mining art, blasting. SUBSTANCE: the invention consists in the fact that the deep-hole charge has a column of explosive dispersed into parts by inert interlayers, and a stemming the layers for charge dispersion are made in the form of discrete-inlet gaps. The upper part of the gap is made of lump material, and the lower one-of corrugated material. The stemming is also made discrete-inert: the lower part-of corrugated material, the upper one-of lump material. EFFECT: enhanced quality of crushing of the rock mass due to redistribution of explosion energy and gaseous products in the length of the deep-hole charge. 1 dwg
