Sobolevskyi R. Quality management of nonmetallic building materials based on geostatistical modeling

The dissertation is devoted to solving the actual scientific and practical problem of quality management of nonmetallic building materials based on geostatistical modeling for grounding the optimal technological solutions that become apparent at the ascertainment of natural and technological parameters relationships which are assessed by integral quality coefficients realized at geostatistical modeling of the effectiveness of technological solutions. For the estimation of prospects of development of deposits, or separate sections, we proposed the new cluster-geometric technique of determining the blockiness. The technique of fractal analysis of regularities in the fracturing formation for various deposits or their sections was developed. A map of spatial variability in fractal dimensionality of fracturing in the labradorite deposits of Ukraine was produced, the use of which will make it possible to increase efficiency of discovering new labradorite deposits, which will meet certain quality requirements. The patterns of change in fractal dimensionality at the different structural levels were established and the methods for their prediction were developed, which will make it possible, by the results of exploring fractal dimensionality at one of the structural level, to predict their values for others to optimize the process of control over geological exploration and extraction operations. As a result of the performed experimental studies, the influence of fractal dimensionality of fracturing in the blast-hole drilling zone on the productivity of the process was proved. We created objective function of optimal process to control technological processes, based on geostructural and technological indices that were evaluated by generalizing index of fractal dimensionality. The objective function of optimal process of drilling the fractured array, which includes indices of fractal dimensionality of the drilling zone, was proposed. For the first time the regularities of change of primary kaolin samples whiteness depending on the results of determination of colour coordinates, the fractal dimension of the sample surface, the size of scanned samples grains and fractal dimension of grains in the massif are established. For the first time the relationship between the geochemical and geostruсtural parameters of nonmetallic building materials deposits is established and the influence of their spatial variability on the effectiveness of selective extraction of nonmetallic building materials is assessed. Based on the first developed technological coefficient of the contact form, the influence of fractal dimension of conditioned areas contours on the productivity of excavation is established when using selective extraction of nonmetallic building materials. Cluster and fractal technique of determining the volumes, operational noncontact evaluation of spatial variability of quality indicators technique and the method of cluster and crigging averaging of raw materials quality are developed.
