Application of hybrid fuzzy weights of evidence model in mineral resource assessment for coal in Chengde area, Hebei, China

The hybrid fuzzy weights of evidence model method and GeoDAS GIS were applied to delineate targets for exploration of coal mineral deposits in Chengde region, China. Based on the comprehensive analysis of relative evidential layers of coal deposits using fuzzy logic method, the five targeting areas were delineated using fuzzy weights of evidence method and were suggested for further exploration. The result not only can be a great referenced value for mineral resources prediction and evaluation but also provides an effective way to combine the knowledge-driven model with data-driven model.
