In order to determine the dependence of the water saturation of crushed rock on the time of impregnation and the mass of the pieces, experimental work was carried out with samples of basalt, tuff and coal. Approximate processing of experimental results using exponential functions is performed. It is shown that the chosen class of functions describes empirical data with good accuracy. It was found that the limiting water saturation depends on the mass of the samples, which indicates the fractal nature of the porous structure of the rocks. The minimum masses of samples for which the porous structure can be considered homogeneous are determined. The obtained dependences make it possible to carry out preliminary estimates of the water saturation as a function of the impregnation time and the mass of the samples. The performed complex of studies allows to determine the water saturation time of the rock under study taking into account the mass of the pieces and the characteristics of the porosity of these materials. The obtained data serve as the initial information when preparing products from the material under study, as well as the technology of their dehydration. The obtained analytical dependencies make it possible to predict the water saturation of the crushed rock mass in preparation for use or further processing.
