| Abstract: | With the development of mining of iron deposits in China, groundwater invasion and the impacts of groundwater drainage, such
as regional groundwater table lowering, overlapping cones of depression, subsidence, and water quality deterioration are environmental
problems which endanger mining production and human life. Effective prevention of water invasion or timely determination of
the mechanism of water bursting and rational design of drainage plans are the most urgent mining challenges. The mechanism
of water invasion and the environment impacts on the groundwater system of the Gaoyang Iron Mine, China were dealt with in
this paper. A systematical investigation of the hydrogeological conditions and monitoring of groundwater dynamics of the mine
were completed. Results show that the limestone of the middle Ordovician System constitutes the under floor of the iron deposit.
This limestone is the main source of water invasion into the mine. Groundwater dynamic equilibrium conditions are broken due
to mine drainage. Water invasion and drainage have caused a serious impact on the groundwater environment of the area. |
