Within a stationary, upstanding cylindrical housing, a piston and a base member resting on the ground are separated by an expansible detonation chamber. One or more gas inlets communicate with the chamber through which successive charges of a combustible gas mixture may be fed into the chamber at a rapid rate and thereafter ignited to initiate a corresponding series of gas explosions. Each gas inlet is connected to a main gas flow conduit which is supplied from at least two independent mixers through separate branching conduits. The mixers are supplied in rotation from sources of fuel gas and oxidizing gas so that only one branch conduit is in use at a time. Spark ignition occurs at each mixer in the same rotation. The branch conduits are connected to the main gas flow conduits in geometrical arrangements which prevent preignition even in long rapid fire shot sequences.
In a gas exploder including a housing having an expansible detonation chamber therein, a charging and ignition system comprising:
In a seismic gas exploder system comprising an expansible detonation chamber, separate fuel gas and oxidizing gas supply means, at least one gas inlet communicating with the interior of said detonation chamber and an external gas flow conduit connected to said inlet, the method of repetitively firing said gas exploder comprising the steps of:
