摘要
在淮北煤田各矿井的地面钻孔测温及井下测温资料的统计分析的基础上,利用各矿井近似稳态孔测温曲线对简易测温曲线进行了校正,计算了各测温孔的地温梯度,并对不同水平深度的地温进行了预测,在横向和纵向上揭示了淮北煤田的地温分布特征。
On the basis of the statistical analysis of the surface borehole temperature measurement and temperature measurement data in coal mines of Huaibei coalfield. The temperature curve of the simple temperature measurement is corrected by using the curve of the approximate steady state hole, and the temperature gradient of temperature measuring hole is calculated, the temperature of different levels of depth is also predicted. Finally in the horizontal and vertical, the characteristics of the ground temperature distribution of Huaibei coalfield are revealed.
