Abstract
A gas generator device (3) is used for breaking or splitting natural and artificial objects when inserted in a drilled hole and ignited to start a burning reaction in a deflagration or non-detonation mode. The gas generator comprises a first part (11) having a first main cavity (12) and a second part (13) having a second main cavity (14). An oxidant and a combustible compound are contained in the first part. A liquid such as water is contained in the second main cavity for distributing the pressure obtained from gases generated in the burning reaction. The first and second main cavities are separated from each other by a bottom plate (21) of the first part that e.g. can be set at a level to adapt the volume of the first space and the amount of oxidant contained therein. The gas generator device is particularly well suited for use in horizontal drilled holes. The first part can comprise a composition using as part of the combustible compound a holding structure of polymer material and added thereto, aluminium or a similar material which reduces the burning time and increases the energy content of the composition. A special ignition unit (27) can be used.
