GAS GENERATOR FOR DESTRUCTION OR CRACKING OF NATURAL AND ARTIFICIAL OBJECTS, AND METHOD OF DESTRUCTION OR CRACKING OF NATURAL AND ARTIFICIAL OBJECTS Russian patent published in 2013 - IPC E21C37/12 F42D3/04 F42B3/04 

FIELD: blasting operations.

SUBSTANCE: gas generator (3) is used for breaking or cracking of natural and artificial structures, being inserted into the drilled boreholes and ignited to start the combustion reaction in the deflagration or non-detonating mode. The gas generator consists of a first part (11) with the first main cavity (12) and a second part (13) with the second main cavity (14). The first part contains the oxidant and the fuse composition. The second part contains liquid, such as water which serves for distribution of pressure generated by the gases formed in the combustion reaction. The first and second main cavities are separated from each other by bottom of the first part (21), which for example can be mounted according to the size of the first cavity and the volume of oxidant in it. The present gas generating device in particular is well adapted for use in horizontally drilled holes. The first part can consist of a composition that uses as a part of the fuse composition the bearing structure of the polymer material and aluminium or similar material added to it, which reduces the burning time and increases the energetic capacity of the composition. Any special igniting device (27) can be used.

EFFECT: gas generator is easy to use, safe in operation, has a lower noise level, enables to carry out more precise separation of objects.
