中文摘要：
地温梯度是度量煤矿热害的一个重要指标，是预测煤矿热害、指导煤矿进行降温工作的基础数据。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4．0732℃／100m。
英文摘要：
A geothermal gradient is an important index to measure a mine thermal disaster is a basic data to predict the mine thermal disaster and to guide the mine temperature reduction work. In order to accurately understand the geothermal disaster conditions in Barapukuria Mine of Bangladesh, according to the adjustment circle theory, a three - wire method was applied to the steady - state temperature measurement in Barapukuria Mine. The method with the linear fitting to calculate the geothermal gradient was provided and the geothermal gradient obtained at -260m level to -430m level in the mine was 4. 0732℃/100m.
