摘要
对淮南矿业集团某矿井筒冻结壁温度场发展与融化过程进行了监测,根据实测数据,分析研究了冻结壁融化过程,得出了不同土质条件下冻结壁融化时间和融化速率,并基于对数函数拟合出了冻结壁温度场变化与时间的关系。
The frozen mine shaft wall temperature field changes and thawing process are monitored for a certain mine affiliated to Huainan Coal Mining Group.The frozen shaft wall thawing process is analyzed and studied based upon the data obtained on-site.On the basis of these,frozen shaft wall thawing time and thawing rate are produced for scenarios under different soil conditions.Also on the basis of logarithmic function,the relations between the frozen shaft wall temperature field changes and time are created.
