SEISMIC MONITORING OF PROPERTIES AND STRUCTURES OF THE UPPER CROSS-SECTION THE ZONE OF A DOLINE BY THE REFRACTION SHOOTING TECHNIQUE

 In the territory of the municipal formation Berezniki (Perm Krai), in close proximity to the town boundary, there are several sites of accelerated ground subsidence connected with mine flooding at the Upper Kama deposit of potash and magnesium salts. Intended to delineate zones of hazardous processes affecting stability of buildings and structures, the integrated monitoring system is put into operation. The research package includes shallow seismic investigations aimed to estimate spatial distribution of structural and physical parameters in the cross-section. The article discusses the seismic monitoring results interpreted under the classical refraction theory and meant for studying changes in the upper cross-section. The analysis also involves data obtained by the common-depth-point method which is standard for high-resolution shallow seismography used in the studies of reflection boundaries within a cross-section interval of mineral deposit. The comparison of the elastic characteristics collected at different stages of monitoring for a period of 3 years identifies the prevailing trends of influence of the doline and specifies the statistically significant changes in the values of the refraction velocities.
