Conclusions
1. The value of the γ potential occurring as a result of sorption of ions of the mineralized solution by the filtering medium in the form of a fractured rock mass is tens of mV and depends more on the structure of the rock and less on the concentration and composition of the solution.
2. In the case of plane-radial flow of the solution the distribution of the potentials and seepage field strength in the injection zone depends on the pressure distribution along the length of the flow from the injection borehole (for grouts — with consideration of sedimentation of the solid particles and filtering the liquid phase) as well as on the permeability of the medium.
3. The seepage zone represents a space-charged body whose potential in the external medium depends on the effective seepage radius.
