| 摘 要： | 龙凤井田7个地温孔的地温特征表明，井田地温及地温梯度主要受地下水因素影响，若地下水流通性差，地温高及地温梯度大，反之，则地温低及地温梯度较小；煤层底板温度值与埋深、底板标高呈二元一次线性回归关系，即与埋藏深度呈正相关关系，与底板标高呈负相关关系。根据煤层地温等值线图，划分出正常温度（无地温热害）范围（≤31℃）、一级高温范围（31℃～37℃）和二级高温范围（〉37℃）。先期开采地段处于无地温热害范围，一级和二级高温范围均位于井田的东部和南部。

| Abstract: | Geotemperature characters of 7 boreholes in the Longfeng minefield showing that minefield geotemperature and gradient are mainly influenced by groundwater, if the groundwater has poor fluidity, then high geotemperature, large gradient and vice versa. Coal floor temperature and buried depth, floor elevation presented binary linear regression relation, that is to say positive correlation with buried depth and negative correlation with floor elevation. Based on coal seam geotemperature isopleths, plotted out normal temperature （no geotemperature heat damage ≤31℃）, first level high temperature （31℃-37℃） and second level high temperature （〉 37℃）. The primary mining sector stands in no geotemperature heat damage area, the first and second levels high temperature areas are located in eastern and southern parts of the minefield. |
