The analysis of rocks movement angles is executed. It is shown, that these angles does not correspond to actual angles, which from the results of measurements are received. This discrepancy is the reason of insufficiently proved constructions protection for buildings, which are located over mining. The values of scope corners and corners of moving of earthly surface are analysed for the terms of mines of Western Donbass. It is rotined that normative angular parameters which are utillized for the prognosis of influence of mountain developments on an earthly surface differ from the actual values of corners which are certain from data of model surveyor supervisions on the observant stations. The indicated disparity is reason of insufficient validity of the applied measures of defence of the earned additionally buildings.
