MATHEMATICAL MODEL AND EXAMPLE OF GROUNDWATER SUPPLY-DRAINAGE CONBINATION IN MINING AREA

On considering the fact that ground water disasters coexist with the shortage of supply resource in most mine areas in the north of China,the authors of this paper have put forward a new concept of supply-drainage combination,An efficient method of calculating drowdown-to-dewatering response matrix and a lexicographic linear nonlinear programing algorithm have been worked out.A linear nonlinear multi-objectives supply-drainage optimizing modle has been built on the basis of the above mentioned work and tried in the case study in Jiaozhuo,Henan province.
