Abstract
The formation of karst cavities, the disintegration of inter-chamber pillars, deformation of the earth surface and inrush of oversaline water into the underground voids, which is especially dangerous within the settlements and industrial complexes, are the results of mining operations and poor mine conservation (by filling the waste space with the salt brines) in the areas of the Kalush-Holyn potassium salt deposit. The geological and geophysical control of the ecological and geological situation at the mines is performed by using the high-precision gravity exploration. The efficiency of gravity method is investigated in the paper and the results of high-precision gravimetric monitoring of the geological environment state at the division of the Skhidna-Holyn mine field at the Novo-Holyn mine are given. This mine is located on the territory of the Precarpathian fore deep. The modelling of changes in the density structure of the geological profile of the mine, i. e. prediction of the integrity destruction of the saline rocks and the salt table, was performed by solving the gravity inverse according to the space-time anomalies of the gravity field.
