摘要:
为预测青藏高原多年冻土区露天煤矿边坡地温变化，揭示多年冻土分布规律，指导寒区露天矿安全生产，以木里煤田聚乎更矿区露天矿边坡2011—2014年地温监测数据为基础，通过数据的统计与拟合，依据传热学理论建立研究区多年冻土地温预测模型，并利用邻区露天矿冻土地温监测结果与数值模拟对预测模型精度进行验证。研究结果表明：木里煤田聚乎更矿区露天矿边坡季节活动层厚度普遍在5.75～6.59 m，多年冻土下限在63.85～64.35 m，地温年变化深度在11.65～12.25 m；采矿揭露后，边坡表层原生多年冻土演化为3.85～5.65 m季节活动层；坡面季节活动层厚度较原生季节活动层厚度略薄，随着冻融循环周期的递增，其厚度逐渐接近原生厚度；冻土地温变化曲线与简谐波波形线接近。本文所提出的冻土地温预测模型可用于预测青藏高原多年冻土区边坡地温变化，研究结果可为寒区露天矿边坡稳定性研究提供技术支撑。
Abstract:
In order to predict the ground temperature change of open-pit coal mine slope in the permafrost area of Qinghai-Tibet Plateau,reveal the permafrost distribution rule,and guide the work safety of open-pit mine in cold region,based on the ground temperature monitoring data of open-pit mine slope in Juhugeng mining area of Muli coal field from 2011 to 2014,a prediction model of permafrost ground temperature in the study area was established according to the heat transfer theory through the data statistics and fitting,and the accuracy of prediction model was verified by the monitoring results and numerical simulation of permafrost ground temperature in the adjacent open-pit mine.The results showed that the thickness of seasonal active layer of open-pit mine slope in Juhugeng mining area of Muli coal field was generally 5.75~6.59 m,the lower limit of permafrost was 63.85~64.35 m,and the annual change depth of ground temperature was 11.65~12.25 m.After the mining exposure,the primary permafrost on the slope surface evolved into a seasonal active layer of 3.85~5.65 m.The thickness of seasonal active layer on the slope was slightly thinner than that of the primary seasonal active layer,and with the increase of the freeze-thaw cycle,its thickness gradually approached the primary thickness.The change curve of permafrost ground temperature was close to the simple harmonic waveform line.The proposed prediction model of permafrost ground temperature can be used to predict the ground temperature change of slope in the permafrost area of Tibetan Plateau,and the results can provide technical support for the research on the stability of open-pit mine slope in cold region.
