摘　　要：在收集和汇总淮南矿区测温资料的基础上,绘制了淮南矿区现今地温梯度分布图,分析其现今地温场特征;并从层间流动和穿层流动2方面分析地下水对地温场的影响。研究表明:受高温灰岩水层间流动的控制,地温梯度>3℃/hm的高温区沿陈桥-潘集背斜轴线走向分布,并形成该区地温北高南低,东高西低的特点;在潘二和杨村等矿井内存在深部高温岩溶水或浅层冷水沿张性断裂的流动,导致局部地区地温异常的现象。On the basis of collecting and summarizing the temperature measurement data in Huainan Mining Area,we draw the distribution diagram of geothermal gradient,and analyze the present geothermal field characteristics,and also analyze the influence of groundwater on geothermal field from two aspects of interflow and cross flow. The study shows that the direction of hot space where geothermal gradient is greater than 3 ℃ / hm is along the axis of Chenqiao Panji anticline,and it is mainly controlled by the interflowing of hot limestone water. So the characteristic of ground temperature is higher in north lower in south,higher in east and lower in west;and the phenomenon that deep hot karst water and shallow cold water flows along tensile fractures leads to regional geothermal anomaly in Pan＇er and Yangcun Mine.
