Prediction of Water Inrush Areas Under an Unconsolidated, Confined Aquifer: The Application of Multi-information Superposition Based on GIS and AHP in the Qidong Coal Mine, China

The complex geological and hydrogological conditions under the unconsolidated and confined aquifer in the Qidong coal mine have resulted in serious water-inrush hazards. Multi-information superposition was used to predict water inrush areas. Six controlling factors (the specific yield, the effective thickness and load transfer coefficient of the aquifer, the fractal dimensional value of bedrock faults, the effective thickness of the protective...
