Water-richness evaluation method of water-filled aquifer based on the principle of information fusion with GIS:Water-richness index method

In order to identify the distribution of the water-richness in water-filled mine aquifer,the aquifers overlying the No.4 coal seam in Pingshuo No.1 underground Coal Mine was studied.After establishing the main controlling factors,the GIS was used to establish the thematic map layers on the basis of making the best of geological data and collecting the information of each main factors,and to stack the multi-source of geological information.Then,the "weight" coefficients of each main factors impacting the water-richness of aquifer were established using the non-linear(such as artificial neural networks,etc.)or linear(e.g.AHP Method,etc.)information fusion methods.According to the use of GIS,the evaluation model of the water-richness distribution was established.Then,the water-richness index was calculated.Finally,the distribution of the aquifer water-richness overlying the No.4 coal seam was put forward and the water-richness evaluation was accomplished.
