| 摘 要： | 从热源、成热环境两方面对三河尖井田地温异常形成机理进行研究后认为，井田内煤系基底处于相对抬高的构造位置，使大地热流增大；不同热导率岩层的叠层式组合，使煤系聚集的热量不易散失；地下水运动微弱，所起的降温作用很小等因素是导致井田地温异常的主要原因。

| Abstract: | The formation mechanism of geothermal anomaly in Sanhejian mine field is studied from both aspects:heat source and teat forming environment,it is considered that the following factors are the main causes resulting the geothermal anomaly in mine field:the base of coal measures in mine field is located in relatively raised tectonic setting,resulting the increase of geothermal flux;the strata with different thermal conductivity are superimposed,and the heat concentrated in coal measures is not easy to escape,resulting the increase of geotemperature,the movement of groundwater is weak,it has a little influence of the drop in temperature,etc. |
