    This paper presents statistical and geostatistical characteristics of the variability of the total sulphur and ash content in part of seam 308 of “Ziemowit” colliery. Statistical analysis of both parameters showed big variability, significant deviations of empirical distributions from the theoretical normal distribution and occurrence of numerous outliers. Geostatistical analysis showed the occurrence of zonal anisotropy in parameters variability and heterogeneity of the seam. Gaussian model was used as a theoretical model of averaged semivariograms . Significant participation of the non-random component and big range of semivariograms confirmed the legitimacy of using geostatiscs for the estimation of sulphur and ash content. Significant decrease of interpolation errors during the transfer from points to blocks interpolation was discovered.

    Ocena niepewności wyników statycznej symulacji sieci gazowych
    (2009) Łaciak, Mariusz
    Modelling and simulating gas-pipe network is a significant part of difficulties during planning as well as operating process. Most of computational methods referred to gas-pipe network, exhibit some errors in calculations. This paper presents reason-effect analysis of errors occurring in statistical simulation. Paper describes most of the parameters related to exploration gas-pipe network that can lead to an error in calculation using statistical simulation.

    First chapter of following paper compiles location and brie characteristic of study area as well as general classification of landslides. In next step selected scarp protection methods were described. Furthermore, statistical data regarding landslides in study area were collected and listed. Final part of this paper is mostly focused on detailed description of selected landslides alongside with protection measures undertaken in the area of Biecz.
