DETONATOR PELLET Russian patent published in 2014 - IPC C06C7/00 F42B1/04 F42D1/04 

FIELD: chemistry.

SUBSTANCE: invention relates to industrial blasting means, namely detonator pellet, intended for initiation of hole charges in drilling and blasting works at mining enterprises. Detonator pellet for industrial blasting consists of charge of explosive substance in plastic shell, provided with canal and one or two sockets and made from injection moulding mixture of trotyl with pentaerythritol tetranitrate (TEN). Mixture contains 45-55% of TEN with specific surface from 1100 to 2400 cm²/g or 56-100 wt % of powder-like pentolite, made on such TEN, of total charge weight. TEN is produced directly in technological process or is obtained by mixing product with specific surface larger than 2400 cm²/g and smaller than 1100 cm²/g, and powder-like pentolite contains from 45 to 55 wt % or from 88 to 92 wt % of TEN, trotyl constituting the remaining part.

EFFECT: invention ensures obtaining charge of higher quality as to homogeneity, more technological in manufacturing and more reliable in exploitation.
