Abstract
The paper presents the results of express research using the natural pulses of the Earth’s electromagnetic field in the Solotvyno salt anticline structure in the Transcarpathia to assess the current stress-strain state of rock mass, to determine local heterogeneities and development of dangerous geological processes forecast. Measurements were made at 410 monitoring points located on 14 profiles. The obtained results were recounted in the complex signal, the values of which vary from 49.25 to 2297.68. In order to assess the variability of the complex signal, its gradients were calculated. Within the mine field of the mine № 9 and along the structure’s north wing the maximum value of the integrated signal and its gradients were established, indicating the maximum mass stress state of these areas. In the region of the southwest periclinal of the structure in the Zaton area the minimum values and gradients were established. Completed research complex allowed to predict the development of deformations of the salt rock mass along the peripheral zones of the mine fields and beyond the forecast subsidence area, including the southern slopes of Mount Mahura with the risk of landslide deformations activation.
