| This paper , taking the Jinshan gangue thermal power plant (being constructed project)life water supply and request as a background, appraised the Qinghemen area ore pit water resources with emphasis, on the base of analyzing this area hydrogeological conditions. It calculated the Qinghemen area ore pit water volume with the numerical methods; Using the gray cluster method appraised the Qinghemen area ore pit water quality characteristic, and has been compared with the synthesis exponential method; Discussed the ore pit water quantity and water quality influencing factor with the traditional geology analysis method and the principal components analytic method; In view of the Qinghemen area ore pit water characteristic, designed the water treatment technical process and established the counter-seepage, EDI and the ionic exchange union desalinization water disposal system. After water equilibrium and the technology economic analysis, Qinghemen area ore pit water resource volume meets the Jinshan thermal power plant life water supply and request, and the processed ore pit water can satisfy the thermal power plant water quality request. Through the benefit analysis, the Jinshan gangue thermal power plant use ore pit water for the life water supply is feasible in the technology and reasonable in the economy. |
