【 摘 要 】

The article discusses issues related to the assessment of the quality of forecasts of continuous deformations of mining areas performed with using modern computer software. One of the elements influencing the quality of forecast is the way of discretization of the extraction field. Such division into discrete elements is necessary, among others, due to the need of integration of the influence function over the extracted area, which usually has a shape that differs from regular geometric figures, for example a rectangle. So, in the framework of this work, the influence of the size and location of elementary fields on the error rates of selected deformation indices has been analyzed. The analysis was carried out using own software called DEFk-Win, that bases on the W.Budryk-S.Knothe prediction model.
