Abstract: The thermal spring is located in Shuinogou dstrit o: Noth-Eatre Urumqi. The parameters obtained by water quality analysis demonstrates that its H₂S, F, PO₄, H₃BO₃, HCO₃+Na+Ca+Mg, Cl+Na+Ca+Mg con-tents exceed all the norme of medical mineral spring water promulgated by WHO. The analysis of various components' content shows that the thermal spring's heat resource is originated from deep layer magmatic column (room), belonging to the high temperature deep layer circulating hot water whose temperature reaches 187.3℃. At same time, the research is taken about cal-culting method of underground heat rsere’s structure, extent，depth and volume, and the volume calculated of its heat reserve is 8 km².
