Abstract: The authors study the ground surface displacement in the area of Zhezkazgan copper ore field now subjected to extraction of ore reserves from rib pillars. The high-precision leveling procedure using digital leveling instrumentation and invar leveling staffs is proposed for the application in arrangement of a geodynamic test site at the settlements of Zhezkazgan and Lermontovo. The steel control survey points are firmly connected with rock mass by means of grouting. The observation results made it possible to detect and evaluate the ground surface displacements.
