Effective numerical technique for solving the direct problem ofd electrical prospecting for homogenous media with inclusions of arbitrary shape and constant or changenable electrical characteristics is suggested. It is based on a simultaneous application of fundamental solution of Laplace's equation for halfplane and principal ideas of the boundary integral equation method and the methods of simple layer potential and collocation, as well as finite-difference correlations inlocal inhomogenous regions with changeable characteristics. Numerical solutions for some mathematical models illustrating the high accurancy and potential abilities of the technique suggested have been considered.
