Measuring of intensity of earthquake is conducted more than from 120 mass explosions on careers. Recommendations are developed in relation to the decline of seismic effect. Certainly physical bases of probabilistic prognosis of seismisity and intensity of air waves from the quarries explosions. Dependence of size is set seismically active charge and a seismic effect is initiated to them from relative distance, correlation of speeds of initiator impulse of longitudinal wave in an array, orientations of group of charges taking into account direction of initiation, spread of speed detonation of group of charges, that allows to use them for the management by the seismic effect of explosions at approaching of the guarded objects. Optimum parameters are got for the fibre-optical sensors of diaphragm type with a spherical pickoff found out cross-correlation connections of intensity of light stream and size of the external influencing (pressure, speed of flow, change of deformation, amplitude of oscillation and others like that). By the developed fibre-optical system, measurings of many parameters of physical processes, which are in statics, dynamic development and swaying state, which confirmed the high sensitiveness (1-2 mkm) of the system, are conducted. The fibre-optical station of supervision is developed after gеоdynamics processes, which passed the test on the open-pit of Krivbass. Product Description popup.authors popup.nrat_date 2020-04-02 Close
