Substantiation of borehole parameters for special hydrogeological research inside impermeable strata

The geologically, hydrogeologically and geotechnically complex Yakovlevo deposit holds the richest iron ore reserves of round 9 Bt within the Kursk Magnetic Anomaly, and is scientifically and commercially valuable for Russia which supplies the domestic and international markets with the tenth of the total iron ore produced in the world. The relevance of the research is defined by the global trend of worsening and complication of mineral mining conditions due to depletion of readily mineable shallow reserves suitable for the extraction by the open pit method. Among other things, the mining industry faces a complexity connected with extraction of ore reserves under undrained aquifers and other water-bearing bodies. The issues connected with estimation of hydrogeological conditions for the special hydrogeomechanical research inside impermeable rock strata to make them safer and more efficient are discussed. The research being planned can enhance reliability of forecasts of water influxes in mines and assessment of hydrogeomechanical processes. In terms of the simplified test problems, the authors give recommendations on modeling hydrostatic pressure distribution in the impermeable strata above underground openings before permeation testing.
