In one exemplary approach, a subterranean geological formation is ruptured along a subterranean borehole interval by arranging several spaced charges along a borehole interval. These charges may be several spaced apart charges of a non-ideal high energy explosive and / or propellant charges. In addition, one or more containers of inert material, such as saline solution or liquid explosives of lower density, may be included in a column of spaced charges, for example, between these charges. Detonation charges can be simultaneous or have independent moments. The charges are preferably designed in such a way as to obtain a unique underground fractured rock structure, containing integrity zones along the borehole interval, containing spaced zones, passing, for example, disk-shaped, radially outwards for a greater distance, passing radially outwardly the distance of integrity zones between these separated zones. |
