This book provides an information fusion model with information
fusion theory, geographic information system technology and modern
mathematical methods to evaluate the risks of groundwater inrushes
from aquifers underlying coal seams. In this new model, the water
inrush vulnerable index was calculated with variable weights
theory. It overcomes the defect of the traditional vulnerability
index method that assumes constant weights for the factors
controlling the water inrush. Mine water inrush events often
occur during coal mine construction and production; they account
for a large proportion of the nation’s coal mine disasters and
accidents in China. Between 2005 and 2014, 513 water inrush
incidents have occurred with a total loss of 2,753 lives. As mining
depths and mining intensity continue to increase, the
hydrogeological conditions encountered are becoming more complex.
The innovative model presented here was applied to two coal mines
in China with proved better results than the traditional
vulnerability index method.
