Complexity of hydrogeological and engineering-geological conditions of the Jakovlevsky deposit and the basic tendencies of their change is characterized at expansion of front of mining works and increases in volumes of extraction of rich iron ores. It is noticed that safety of conducting mining works is defined by formation and development of dangerous mining-and- geological processes. Substantive provisions of forecasting of mining-and-geological processes on Jakovlevsky mine are resulted. Possibility of occurrence of underground waters breaks from undrained water bearing horizons is considered. Ordering of processes of native and native-technogenetics genesis within an allotment of Jakovlevsky mine is executed and the basic directions of actions for increase of safety of exploitation of mine are planned.
In article researched difficult hydro-geological conditions of the Jakovlevsky deposit rich iron ores on which mining going under not-drained high-pressured bottomcoal water-bearing horizon. The purpose spent monitoring is resulted. The comparative analysis of results of three cycles of a hydro-geological monitoring which has shown gradual expansion of front of an over flowing of underground waters from not-drained horizon is made. Negative consequences of such process are specified. The development features of various biological forms of a life in mine which destroy construction materials are noted. Actions for decrease in consequences of an overflowing are planned.
Specificity of hydro-geological conditions of the Jakovlevsky deposit and operating system of a drainage on the mine with the same name is resulted. It is underlined that mine works are conducted under not drained high pressure water-bearing horizons. The complex hydrochemical and hydrodynamic monitoring of underground waters is considered as implement for increase of safety of extraction mine works in difficult mine-geological conditions. The comparative analysis of hydro-geological monitoring three cycle’s results which has shown gradual expansion of underground waters overflowing front from not drained horizon is carried out. Negative consequences of such process are specified. The development features of various biological forms of a life in mine which destroy construction materials are noted. Actions for decrease in consequences of an overflowing are planned.
