Abstract (en)
[origin: US6520089B1] A method for setting and igniting a charge of explosives for geological investigations, comprising the following steps: a hole (14) is drilled in the ground (12) which is to be investigated; an explosion chamber (22) is hollowed out, whereby said explosion chamber has an expanded form in relation to the bore hole (14) at the end of said bore hole (14); an ignition element (34) and an explosive container (36) containing an explosive in a protective blister (54) surrounding the ignition element are lowered down into the explosion chamber (22); the explosive (42) is pressed out of the explosive container (36) into the explosive chamber (22) and the ignition element (34) is ignited In comparison with conventional methods, the inventive method provides for a considerably smaller diameter of bore hole, whereby said bore hole is substantially easier to drill.
