Abstract：The heterogeneity of karst water system is the key challenge for water prevention and control in metal mineral deposits with karst water in southern China.Taking Makeng iron mine as the subject,the distribution heterogeneity characteristics of hard structural factors including faults,karst,igneous rocks are identified by data mining of all the hydrogeological information available in this paper. In addition,the characteristics of karst water system in natural condition and dewatering conditions are analyzed by drawing the water level contour maps of 7 different periods.It is concluded that the fault and karst,which control the concentrated runoff zone of karst water,can be used as the main target of advanced water detection and dewatering.Karst water system shows strong heterogeneity un-der the influence of igneous local impermeable belt.The ore body of Makeng Iron Mine can be liberated effectively and its production can be increased rapidly by multi-phase prevention and control of the karst water in the mining area,utilizing the local igneous imper-meable belt,which can ensure its sustainable development.
