| 摘 要： | 为了准确了解孟巴矿的地热灾害情况，根据调热圈理论采用三线法对孟巴矿进行了稳态测温。提出了利用线性拟合计算地温梯度的方法，得出孟巴矿-260m至-430m水平的地温梯度为4.167℃/100m，详细分析了孟巴矿地温正异常产生的原因。结果表明孟巴矿地温正异常主要影响因素为：岩石的导热率、地质构造、 含水层、采空区浮煤窒息氧化。

| Abstract: | In order to accurately know geothermal disasters situations of Barapukuria Mine, according to the hot circle theory, using the three line method measured the Barapukuria Mine steady-state temperature . Puting forward the method by using linear fitting calculate geothermal gradient, and get Barapukuria Mine -260 m to 430 m-the geothermal gradient is 4.167 ℃/ 100 m, and analyzed the reasons of abnormal temperature in details . The results show that the main factors affect the abnormal geothermal of Barapukuria Mine are the thermal conductivity of rock, geological structure, aquifer and float coal choking oxidation in the goaf. |
