Geoecological problems which can be solved by electroexploration methods and justified<br>necessary complexation of techniques and consequence of their application are determined with the physicalmathematical<br>investigation and natural experiments on various object. Geoelectrical system include dipol<br>and differential electrical profilation, electromagnetic sounding method and study of the electrical field of<br>spreading currents. These geoelectrical techniques for the solution of geoecological problems on Ural, on Far<br>East, and in Kazakhstan was applied.
