Zusammenfassung:	The invention relates to a wellhead system for mining underwater resources. The wellhead system comprises a sleeve, a sleeve head and a suction pile, wherein the sleeve is used for mining the underwater sources; the sleeve head is arranged at the top end of the sleeve; the suction pile is arranged on the periphery of the sleeve in a covering mode; and a sleeve catcher is arranged at the upper end,covering the inner side of the periphery of the sleeve, of the suction pile, a locking structure matched with the sleeve catcher is arranged on the periphery of the sleeve, and the locking structureand a slope surface of the inner circumference of the upper end of the sleeve catcher realize structural matching through a slope surface of the periphery of the lower end of the locking structure toenable the locking structure to be matched with the sleeve catcher to form a ''double hanging'' structure for reducing water flow resistance when the sleeve moves downwards. According to the wellhead system for mining the under
