Despite of classic geodetic measurements, which are used in mine surveying at the beginning, more new technology are applied to measure deformation of structures and surface in mining areas. In the article new technologies are described for utilitarian aims based on strain sensors, laser, scanners and drones. The application of new technologies are especially useful when direct access to measured object is impossible using classic methods and in situation where continuous or quasi-continuous measurement is necessary. In Central Mining Institute the research has been conducted to understand the phenomenon of surface deformation induced by underground mining comparing predicted and measured values before and after extraction. In the last 20 years the mining technology has changed and dynamics of structure and surface deformation induced by mining. The second reason of technology development is necessity to instantly inform users of land and structures about changes using for instance the Internet.
