Abstract: The paper analyzes the data for approximate steady state temperature measurements of 2 boreholes and simple temperature measurements of 44 boreholes in Shunhexi orefield of Yongcheng City, and establishes data model through data fitting combined with the geological information of orefield to reflect the relationship between temperature increment at the bottom of approximate steady state boreholes and static well time. The bottom temperature of simple temperature measurement borehole is corrected according to the data model, and the linear relationship between buried depth and temperature is found through data fitting. On this basis, the horizontal and vertical distribution law of geothermal temperature in the study area is analyzed for reference of further mining development.
