Abstract
This paper presents the results of gravimetric studies carried out at a potash deposit to obtain the information on negative engineering–geological processes in rocks caused by subsoil development. The developed high-precision monitoring gravimetric observation method makes it possible to determine field variations over time. The created physicogeological gravimetric monitoring model is a homogeneous geological medium with an isolated area with a variable rock density. The dynamic gravity anomaly processing and interpreting based on the synthesis of qualitative and quantitative methods for obtaining the geological information from the gravimetric data have been adapted for the gravimetric monitoring purposes. The interpretation resulted in a distribution area and a probable depth interval of rock decompaction, as well as rock density variations, which characterize the decompaction rate. Examples are given in relation to testing the developed technology for dividing the decompressed zones into natural and man-made zones at the Verkhnekamskoe potash deposit in order to improve its operation safety. The monitoring gravimetric observation results can be used to predict the dangerous geological process areas and to control the subsidence of the earth’s surface.
期刊介绍:
Russian Journal of Pacific Geology publishes the results of research on the Earth crust and mantle composition and provides articles on the geological structure and patterns of distribution of mineral deposits in the Pacific Ocean, marginal seas and continental margins. It discusses the topics of stratigraphy, sedimentology, magmatic activity, and seismicity. The journal deals with the problems of lithosphere plates tectonics, and offers the results of neotectonic, geomorphological, geodesic, environmental and mining studies in the Pacific region. The journal accepts theoretical, methodical and philosophical articles covering general issues of geology, geophysics, geochemistry, geoecology and mining. The journal also publishes critical notes and comments, and reviews.
