DEVELOPMENT OF A COMPLEX METHOD FOR FINDING WATER ZONES OF A ROCK MASSIF TAKING INTO ACCOUNT THE STRUCTURAL-TECTONIC AND CURRENT GEODYNAMIC FEATURES OF A SUBSOIL AREA

Abstract

The article presents material on the development of a comprehensive methodology for determining the aquifers of a rock massif, taking into account its modern geodynamic activity and structural and tectonic features. The relevance of research bases on the occurrence of disasters of a natural and manmade nature, such as: flooding of underground mine workings, collapse of quarry walls, breakthrough of quicksand, etc., which are associated with the flooded state of the rock mass.
The problem solved in the research is to increase the efficiency of carrying out measures to drain mineral
deposits by determining the locations of dewatering
wells.
The object of research is a rock mass, which is in a watered state. The subject of the study is the dependence of the formation of water cut in a rock mass on modern geodynamic movements.
The research includes a set of the following methods: hydrogeomechanical analysis, the purpose of which is to determine the spatial orientation of tectonic faults and their kinematic type; the method of exploration geophysics (median gradient method - MGM), which allows us to identify and map zones of reduced resistivity i.e. tectonic disturbances; and the method of spectral seismic profiling (SSP), the purpose of which is to determine the depth of the zone of fracturing of the rock mass.
The obtained research results we presented in the form of a structural-geoelectric model, reflecting areas with high water permeability of the rock mass, which allows the most accurate location of waterreducing wells.
The study of the dependence of the formation of permeability zones of a rock mass on modern geodynamics will significantly improve the quality of drainage of mineral deposits located in difficult hydrogeological conditions and, as a result, minimize the risk of disasters, improve the quality of raw materials and the efficiency of mining operations, and significantly reduce the cost of building of drainage systems.
