| 摘 要： | 涡北煤矿存在地热异常现象,测温孔地温梯度高达3.33℃/hm。为揭示矿区地温场特征,根据测温孔资料和矿山生产地质资料对主采煤层82煤底板温度与埋藏深度之间关系及地温梯度等值线分布特征进行研究。结果表明:F26,F22断层对地温分布控制作用明显,该区地温异常的原因是深循环地下水上升引起局部地温增高。

| Abstract: | Abnormal geotherm exists in Guobei Coal Mine and the highest gradient of temperature in borehole is 3.33 ℃/hm.In order to reveal characteristics of ground temperature field,based on geo-temperature measured in boreholes and geological data,relationship between temperature in the floor of major mining coal-bed 82 and the coal bed occurence depth,and the distribution of geothermal gradient contour were studied.The results show that the fualts F26 and F22 play an important roal in control of geotherm distribution.The reason of abnormal geotherm is that in the area deep cyclar groundwater elevation results in local high geothem. |
