摘　　要：基于对淮北宿临矿区的地温场研究,分析了研究区现今地温场的分布特点,并据此揭示了研究区构造对现今地温场的控制作用.研究表明,宿临矿区地温场分布明显受构造控制,徐宿推覆构造上、下盘地温场差异明显,上盘地温梯度值明显低于下盘;背斜隆起区地温梯度高于向斜凹陷区域,童亭背斜为一整体地温梯度相对偏高的构造单元;研究区断裂对地温场分布有着重要影响,在大断裂交汇处、断裂密集处地温梯度也相对偏高.Based on the study of present geothemal field in Sulin mine area of Huaibei coalfield, the distribution characteristics of present geothemal field in the investigative region were analyzed, and the structural control on it was revealed as well. The results show that the distribution of present geothemal in Sulin mine area is obviously controlled by structures. Firstly, Xusu nappe markedly influences the geothemal field, whose gradients in hanging wall are clearly lower than in footwall. Secondly, gradients in anticlines are always higher than in syncline depres- sion, and Tongting anticline is whole relatively higher than other structure units. Furthermore, geothemal field influences by the distribution of the faults, the unconventionally high-temperature regions appeares in the intersections of dominative faults and the dense faults parts.
