Formation and development of mining-and-geological processes in relation to changes in engineering-geological and hydrogeological conditions on Yakovlevsky mine

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.

Hydro-geological monitoring on the Jakovlevsky mine as implement of increase safety conducting mine second working in difficult mine-geological conditions

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.

Complex monitoring of underground waters on the Jakovlevsky deposit of rich iron ores and its role in increase of mine works conducting safety in the conditions of not drained water-bearing horizons

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.
