Based on the ground temperature date from Zhangyoufang mine and combining geology and thermodynamic theory, the mine belonged to the context of normal temperature normal temperature zone. At the deep of 546 meters, the following may be the first level heat injury(>31℃), and in the 799 meters the following may be the second level heat damage. During exploration the average geothermal gradient was 2.07 degrees Celsius per one hundred meters. Geothermal anomalies in some simple thermometer hole correction and its characteristics of ground temperature distributionarea were determined by the area coal, geological structure, activities of groundwater and many other factors.
