In order to study the influence of transmission medium for hydraulic support on the water resource of mining area, the chemical composition and content of organic and inorganic components no less than 0.1% in emulsified oil used for hydraulic support in underground of coal mine were determined. According to the standards for drinking water quality (GB5749-2006), the incoming water and outgoing water stored in goaf were tested. The content of visible matter and boron in the incoming and outgoing water of water treatment plant exceeded the standard limit, organic and other inorganic components did not exceed the standard limit. With specified components verification test, the components of emulsified oil were not detected, because the amount of emulsified oil used for hydraulic supports was very limited compared to the huge amount of mine water or because the components of emulsified oil were adsorbed or biodegraded, the emulsified oil did not pollute the mine water.
