| 摘 要： | 通过监测淮南顾北煤矿深厚钙质黏土地层井筒冻结压力的发展规律,发现不同深度处的冻结压力在井壁混凝土浇筑后的最初15 d内增长速度较快,且具有明显的方向性;获得外层混凝土井壁浇筑后井帮温度的变化规律,冻结壁融化深度等是直接关系到冻结压力发展的重要因素;结合类似工程监测数据,获得了井筒平均冻结压力随深度变化的线性关系式.

| Abstract: | With the monitoring and measurement on the freezing pressure development law of the mine shaft in deep thick calcareous clay strata in Gubei Mine of Huainan,it was found that within the initial 15 days after the mine shaft concrete lined,the freezing pressure in different depths increased fast with obvious direction tendency.The temperature variation law of the mine shaft inner linear obtained after the mine shaft outer concrete linear made and the melt depth of the freezing wall of the mine shaft were the ... |
