The author proposes original grounds for the classification of the full range of soil masses as a supplement to the classification of soils provided in GOST 25100—2011. The author proposes four classes of soil masses, each class having several types and sub-types of soils. The classification will improve the accuracy of engineering and geological surveys and computer models of the geological environment developed for the purpose of design of buildings and structures. The author offers a classification of soils to identify the geological environment comprising one or more types of soil which are genetically and structurally distinct. Any soil mass type differs by its origin, and, as a consequence, its internal geological structure, stress-strain state and inherent geological processes. Any genetically isolated type of soils a specific program of research, both in terms of methods and in terms of density testing in the point of sampling. The behavior of rock masses together with the engineering structure is pre-determined by the properties of the rock, its relative position (geological structure), a network of cracks and other weakening factors, and the natural state of stress. The fracture network is of paramount importance. Cracks are characterized by direction, length, width, surface roughness of walls, and a distance between parallel cracks.

Application of mathematical methods of optimization of the process of filtration as part of recovery of used engine oils is considered in the article. The method of the full factorial experiment which contemplates generation of the mathematical model of the filtering process is applied with account for numerous factors and missing data. The mathematical model provides the information about the influence of various factors to identify the quantitative values of response functions in the pre-set mode of the process to serve as the basis for optimization.Permeability of polymeric membranes, liquid flow velocity and temperature have been chosen as filtration optimization criteria. As a result of the mathematical processing of the experimental data, factors have been calculated and verified in terms of their importance, and the process description has been provided in the form of a regression equation. Dependences obtained by the authors are recommended for use in the calculation of the process of permeability. For example, they may be used to substantiate the periodicity of maintenance of filtration units.
