“…Результаты инженерно-геологических и гидрогеологических исследований Лебединского и Михайловского месторождений КМА показали потенциальную возможность экономически эффективной [2,3] и безопасной отработки запасов Яковлевского месторождения (1952-1954 гг.). По мере доразведки месторождения и получения новой геологогидрогеологической информации об участке работ менялись представления о его генезисе, геологическом строении и гидрогеологических условиях.…”

“…Для оценки гидравлической связи между НВГ и РВГ в 1991 г. проведено краткосрочное отключение насос ного оборудования скважин на 10 дней. В период отключения уровни в НВГ и РВГ восстановились на 120 и 5 м соответственно [2]. Специалистами института ВИОГЕМ была решена обратная задача на трехслойной геофильтрационной модели по определению коэффициента фильтрации разделяющего водоносные горизонты слоя (прослоев сланцеватых и углистых глин в основании НВГ), который составил 1•10 -6 м/сут.…”

History of origination and evolution of mankind reflects an increasing demand and unexampled value of iron ore. Russia is the world's fifth producer of round 120 Mt of iron ore annually and the world's top holder of 59 Bt of iron ore resources. The weight of Yakovlevo deposit in this regard is proved by approximately 9 Bt of high-grade iron ore. The present-day challenge of the national mineral sector is to ensure safe, incremental and sustainable production of iron ore under increasing demand of the day. Meeting such goal eventually assumes proper design solutions connected with complex geology, hydrogeology and geotechnology. One of the problems in this regard is safe mineral extraction under undrained high-pressure aquifers, which includes stability of underground openings and reliable prediction of water inflow. This study uses specific geological and hydrogeological data of Yakovlevo deposit, as well as the previous design solutions to analyze adjustability of water inflow map at the stage of mine operation toward further forecasting of hydrogeological conditions of mining. The drainage and monitoring guidelines should be preceded by checking the output fidelity using a hydrodynamics method and the numerical geoflow modeling. However, it is alre ady possible to state that the promising methods of hydrogeomechanical monitoring of the impermeable strata at Yakovlevo deposit are the high-frequent measurements of groundwater pressure and chemistry using loggers, and the regular measurement of deformations and permeabilities at check points. The recommendations on hydrogeological monitoring development in mineral mining are formulated.

The authors suggest using the water catchment model with concentrated parameters for prediction of seasonal variation in water inflow to mines. The efficiency of the slope runoff model application was previously shown on the base of three test subjects operating apatite-nepheline ore deposits in the Khibiny massif. The article provides a simple methodology for water inflow prediction which doesn’t require any specific software. The example is provided of using this methodology for monthly water inflow prediction based on an underground mine in Kuzbass.
