| 摘 要： | 针对丁集煤矿矿井高温热害严重的问题，采用井下炮眼温度测定方法，测量地温；借助有限元ANSYS的热耦合分析程序，模拟岩巷和煤巷调热圈，修正矿井地温，确定地温梯度．预测该矿深部地温。结果表明，该矿-500m水平以上、以下的地温梯度分别为3．5、4．0℃／hm；采煤层深度为一600m以下的地温在38℃以上，属于二级热害区。该研究可为矿井深部降温提供数据参考。

| Abstract: | This paper seeks to address the serious high temperature in Dingji coal mine, by using the downhole borehole temperature-determining method for measurement of the ground temperature. The paper highlights means of finite element ANSYS thermal coupled analysis program for simulation of the rock and coat tune hot laps, revision of the mine temperature, and determination of the ground temperature gradient to predict the temperature in deep mine. The results show that the mine occurs as the second-class thermal damage zone with the ground temperature gradient of 3.5,4.0℃/hm above and below the level of -500 m and the ground temperature of above 38℃ in depth of -600 m in coal seam. This study provides reference for the deep mine cooling. |
