Abstract
A method for setting and igniting a charge of explosives for geological investigations, comprising the following steps: a hole ( ) is drilled in the ground ( ) which is to be investigated; an explosion chamber ( ) is hollowed out, whereby said explosion chamber has an expanded form in relation to the bore hole ( ) at the end of said bore hole ( ); an ignition element ( ) and an explosive container ( ) containing an explosive in a protective blister ( ) surrounding the ignition element are lowered down into the explosion chamber ( ); the explosive ( ) is pressed out of the explosive container ( ) into the explosive chamber ( ) and the ignition element ( ) 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.
