APPRAISAL ON EXTRACTION OUTPUT OF THE GROUND WATER IN A CERTAIN COAL MINING AREA BY APPLICATION OF THE PREDICTED LINEAR PROGRAMMING

A predicted linear programming model is set up for the appraisal on extraction output of the ground water in the water-source zone of a certain coal mining area,both for the present and the different stages in future.The maximum extractions in different stages can be derived from this model and an optimal programme can be prepared accordingly to form the basis for decision-making in the development of the coal mining district.
