Abstract. The preliminary experiments on the integrated method of dehydration shown the effectiveness of electro-in conjunction with other methods of influence on the wet raw material mining. In this paper to describe the effect of an external electric potential and the differential pressure on the efficiency of the dewatering of bulk material layer process offered a simplified mathematical model, limited within a narrow channel theory. The analytical expressions, which indicate that the residual moisture layer is linearly dependent on the differential pressure and tension. The mean square error of approximation straight line in relation to the experimental data does not exceed 2.5%. This indicates that the model assumptions made and judgments are legitimate and theoretically obtained a linear dependence of the residual moisture from the vacuum and an electrical p otential difference is performed accurately in the dewatering crushed rock mass. The results are limited by the high saturation assumption since the liquid and require further theoretical and experimental studies for deeper degrees of dehydration.

Keywords: vibration, electro-osmose, dehydration, complex method, mathematical model, electric field.
