摘　　要：矿井热害是目前淮南煤田煤矿地质工作的主要研究内容之一。文中在汇总和分析井田内32个地面钻孔井温测井数据和2个井下巷道岩温测试数据的基础上,绘制了地温-深度关系图、地温梯度-深度关系图以及井田现今地温梯度分布图,并探讨了该区现今地温场特征及其影响因素。研究表明：朱集井田现今地温梯度介于1.7~3.8℃/hm,平均2.83℃/hm,地温整体较高,在垂向上表现为传导型增温特点,在平面上表现为南高北低、东高西低的特点;地质构造对区内现今地温场起着主要控制作用,岩性特征和地下水活动对地温场的分布也有一定的影响。Mine heat hazard is one of the main research content of the coal mine geology work in Huainan Coalfield. On the basis of collecting and analyzing 32 logging temperature data of surface boreholes and 2 temperature test data of surrounding rock of underground roadway in Zhuji Coalfield,the present geothermal field distribution characteristics of the area is discussed,which include the relation curves of geo-temperature and its gradients with depth,and the distribution of present geothermal gradients,and its influential factors are analyzed. The results indicate that present geo-temperature gradients of this area are between 1. 7 ℃ / hm and 3. 8 ℃ / hm,the average geo-temperature gradient is about 2. 83 ℃ / hm,which slightly higher than the adjacent mines. It show the transmitting characteristics of warming in depths,and on the plane show the characteristics of geo-temperature lowering from south to north,east to west. The geothermal field in the area is mainly affected by the geological structure,and the lithology and groundwater movement can also have affect on it.
