Abstract: This paper considers the processes of activation in ground subsidence movements in flooding mine workings of mines being liquidated in two districts in Donetsk city on the area of more than 60¤@km². A concept is given to build up control network of geomechanical monitoring in conditions of existing old mining operations at shallow depths £¨down to 100¤@m£©, strong damages of objects of urban building. Given are GPS network structure, layouts for location of basic and local profile lines, special control stations for monitoring ground subsidence movements over the territory of mines being flooded. Results of the series of observations made are discussed and their accuracy is analyzed.
