Abstract

The results of application of spatial applied statistics methods - geostatistical tools used for modeling, estimating, forecasting and simulating data, i.e. values of parameters describing various regionalized phenomena, analyzed in geological-mining, environmental, geodetic and energy issues, were presented.The following methods were used: linear geostatistics (ordinary kriging, simple kriging, lognomal kriging), quick interpolation techniques (linear model kriging, inverse distances) and non-linear geostatistics (kriging with external drift, bundle indicator kriging, conditional turning bands simulation). The subject of spatial analyses were various problems. It is possible to mention the development of spatial models of polymetallic Cu ore deposits variability, occurring in the Lubin-Sieroszowice region (SW Poland), anisotropy of variation in deposit parameters, uncertainty estimation, risk assessment, determination of the probability zones of exceeding the assumed thresholds for deposit parameters, the filtering of the components of theoretical variograms models of Cu ore deposits parameters, as well as variability of porphyry copper deposits parameters in Peru (Rio Blanco). Geostatistical methods were also used in environmental studies. The subject of interest was the integration of environmental data (concerning soils and groundwater, heavy metals content), estimation of the contamination of soil layers (surface, subsurface) with heavy metals and the determination of anomalous heavy metal content zones, shown for some regions of the southern part of Poland , environmental risk assessment, variability of technological parameters of ash-slags (near Torun, Poland). Quite different a new application was development of spatial and spatio-temporal (2D, 3D) hydrogeochemical models of variation of underground waters quality parameters for a water intake area, and also of a treated water and in water supply system. An interesting experience was the adaptation of geostatistics to analyses related to agriculture and enzymology, to assess the state of spatial distribution of selected enzymes in the surface layer of land, shown against the background of geological-engineering conditions in the Warmian-Masurian region, NE part of Poland. The application of geo-statistical methods to modeling, estimating and forecasting displacements on the basis of data from the geodetic monitoring, also allowed to create spatial models (3D) for a large hydrotechnical object, extremely useful and important, due to its state of safety (SW part of Poland). An extremely innovative area was an attempt to adapt geo-statistical methods to solve issues related to energy, and also located on border of energy and economics. We should mention here the modeling, estimation and forecasting of electrical loads in the 220, 400 kV transmission network and 110 kV grid, as well as modeling and estimating marginal costs of electricity transmission to transmission network nodes at different time points (season, day) for a whole territory of Poland. Areas of application of methods of applied (spatial) statistics are still increasing, practically unlimited. Reaching for such tools also determines the constantly increasing amount of data. This requires the use of effective tools for their processing and geostatistics are undoubtedly one of them.
