Abstract

20,445. Lamour, J. Sept, 8, 1911, [Convention date]. Blasting.-A blasting- device comprises a strong closed casing a inserted in the borehole, having in its side a pressure member d with packing e, and containing water, for transmitting the explosion pressure to the pressure member, and an electrically - fired blasting - cartridge g. The cover is secured by a wedge b. A piston may be interposed between the water and the blasting-charge.
