By results of geodynamic zoning positions of relief altitudes and specific peculiarities are mapped (in particular, linear structures, areas of mega-fissility, local anticlinal and synclinal structures, neotectonic active anticlinal dislocations and active faults); sign and amplitude are identified for common tectonic movements and other indices, which are prone to layers deformation and displacement in process of deposit exploitation. In process of the facility exploitation aerial and space image survey should be repeated at least twice a year. The above indices are specified at the map; their quantity, location, parameters and changes in orientation of deformation vectors are compared with the same data obtained before exploitation. When by result of next aerial and space image survey geomorphologic indices are exceeded in comparison with the same indices obtained before exploitation at least per 10% geodynamic test site is created. At that laying of survey marks and observation over their displacement is started in the areas of dynamic influence of active faults and in the areas of high modern relative deformations. When deformation values for survey marks reach hazardous values for buildings and structures in the affected area, engineering measures are taken to reinforce structure of buildings or structures or to stop operation of the underground facility.EFFECT: optimisation in reliability of control results.4 cl, 3 dwg
