Analysis of Groundwater Inrush Conditions and Critical Inspection Parameters at the Baixiangshan Iron Mine, China

The Baixiangshan Iron Mine is a large, complex deposit. The mine is endangered by several groundwater inrush factors: multiple aquifers, high water pressure, transmissive faults, and minor hidden faults, joints, and fissures. Through a systematic hydrogeological investigation, locations where the major roadway intersected with faults in the aquifers were identified. Critical inspection parameters to predict the potential of groundwater inrush were then calculated for the intersections between the major roadways and the transmissive faults. Finally, control measures are proposed that incorporate the high groundwater pressure and the high dip angle faults. The results of this research can be applied during development of the Baixiangshan Iron Mine.
