Seismic emission system for use in an underground formation, using at least one seismic source movable successively in a plurality of prepared activation locations and method for implementing same. The method comprise computer-implemented steps of modeling at least one physical property of a mixture of at least two chemical species by determining at least one conceptual segment for each of the chemical species. Either or both the end plate or the front plate contain termination means for connection to a structure, such as for example bolts, threads latches or other locking mechanism.
