Abstract: This paper studies the impact of mining activities in coal mines on the hydrodynamic environment in runoff areas of karst water drawing from hydrochemistry and hydrogen oxygen isotopes. The conclusions showed that the hydrodynamic characteristics of a strong runoff karst water area had been significantly changed after mining activities. The water velocity became slow and the hydraulic gradient increased; hydraulic connections between karst groundwater and the others were compacted and complicated. The mineral dissolution and hydrodynamic environment varied with different disturbance intensities. The hydrodynamic environments of karst groundwater in various runoff karst groundwater areas were different with different developmental stages of coal mine.
Key words: groundwater water flow system; water chemical composition; hydrogen and oxygen isotopes; difference of mineral dissolution; coal mining area
