Scientific basis for the creation of a drainage system for flooded deposits, taking into account the structural and tectonic structure and modern geodynamic activity of the subsurface use area

The article discusses the scientific framework for the development of drainage approach to watered fields by creating point borehole water intakes that can intercept water flows in rock mass in places of the maximum water yield with no regard to the total area subjected to drainage. The methods and techniques used by the author for the predictive assessment of water transmissivity in rock mass are based on the knowledge of the mechanism and distribution of hydrodynamic flows in rock mass enclosing a mineral deposit. The technologies used and the modern equipment of geodetic and geophysical studies allow sufficiently accurate determination of the modern geodynamic activity and stress–strain behavior of rock mass, which enable structural-and-tectonic modeling and design of drainage systems for watered fields. The article also provides brief information on methodology of the research, parameters of rock mass and hydrogeological characteristics, examples of work implemented and the results obtained. Unfortunately, not all companies are willing to modify the existing drainage systems, even though there are no visible results of the dehumidification or water suppression methods used. The field drainage methods described in the article and implemented in mines in Russia and Kazakhstan have proved their effectiveness. The developed approach to the hydrodynamics analysis allows using the presented method not only in drainage of mineral deposits, but also in water supply of subsurface use objects in different industries.
