Zusammenfassung:	PCT No. PCT/US93/09683 Sec. 371 Date Mar. 18, 1996 Sec. 102(e) Date Mar. 18, 1996 PCT Filed Oct. 7, 1993 PCT Pub. No. WO95/09969 PCT Pub. Date Apr. 13, 1995A fluid actuated detonating device is shown being used to activate explosive devices in a borehole. The detonating device has an explosive detonation charge arranged in a housing wherein a rupture disc in the wall of the housing separates the explosive charge from a fluid environment so that when pressure in the fluid environment is raised to a sufficient level the rupture disc fails and communicates a sudden pressure wave to the explosive to detonate the explosive.
