This paper presents the results of precise measurements temperature and pore pressure in “reservoir–well” system during development iron ore deposits Kursk Magnetic Anomaly (KMA) via blasting. For observation period from October 2021 to June 2024, variations compressibility, permeability upper Albian-Cenomanian confined aquifer, which is used for district water supply, were determined. The general trend a decrease was traced (from 12 °C 11.4 °C). It accompanied by an increase hydrostatic head 3.7 m 7.4 m).
