Abstract
An image of deformations on the areas over mining exploitation is highly disturbed. A series of natural and technological factors causes disturbances that can have accidental, systematic and outlying character. Before analyzing state of deformations the results should be filtered in order to eliminate the outliers. A main problem is to identify if a given value is an accidental disturbance or an outlier. The work presents statistical tests used for recognition of the outliers. The considerations are illustrated by practical computations for the horizontal strains obtained thanks to geodesic measurements on the area affected by underground mining activity.
