High and variable values of velocity gradient are usual for seismic cross section in ore deposit regions. Refraction traveltime - turnes interpretation is very hard by using traditional methods. This paper illustrates possibility of new refraction interpretation technique using local approximation of real velocity fields by homogeneous functions of two coordinates. This 2-D inversion method is simple inversion method for two reversal traveltime curves. Final cross section for complex traveltime curves system is constructed by superposition of total velocity fields corresponding to different pairs of reversal traveltime curves. This is full automatic technique not interactive.
