THE OPTIMAL DESIGN ON WATER DRAINAGE IN NANDING COAL MINE

On the basis of the careful analysis of hydrogeological conditions of Nanding Coal Mine area, the writer has established a conceptual model of hydrogeology and its quasi- 3-D mathematical model for the multiple-aquifer system. The hydrogeological parameters of the model have been identified by the optimal theory. Then,the ground-water flow system management model has been developed. The optimal solution of the management model has been obtained by means of unit response matrix.
