HYDRODYNAMIC FIELD DRIVING EFFECT AND MATHEMATICAL MODEL CONSTRUCTION OF WATER QUALITY FORMATION AND EVOLUTION IN COAL MINE

The change of regional hydrodynamic field caused by coal mining process affects the multi-field process of the formation and evolution of mine water quality, which may lead to the pollution of the water environment in the coal mining area.Research on the driving mechanism of the hydrodynamic field and the method of quantitative calculation of key p
