The methods are suggested for treatment of the results of optical distance and levelling measurements at the underground geodynamic polygons involving in their calculation the tensors of additional stresses and deformations, component of rotation and specific energy of deformability. As an example, consideration is given to changes in time of movements, deformations and specific energy of deformability at one of geodynamic polygons of the Kola peninsular.
Methods of earth's surface and underground light-distance-measurements poligons for geodynamics monitoring in apatite output in Khibin mountains are described.
At development of mineral deposits the systems with open cleaning space are widely used, as a result of which cavities of significant sizes are formed in rock massifs. This creates an immediate danger when working in areas adjacent to the excavated spaces, and threatens buildings, structures, sites located on the day surface. ...
