摘要
煤炭深部资源开采过程中,采用局部保温冻结技术的特殊凿井法逐步得到应用并显示出较大优越性。文章结合特厚冲积层矿井冻结工程,给出局部保温冻结设计的优化计算;提出采用合理的局部保温方案。特厚冲积层上部和下部的冻结壁厚度、冻结壁位移等均能满足施工要求。
During the period of exploring of coal in deep alluvium, application of special sinking method which use partial insulation freezing technology has show the advantages. The paper gave optimal calculation of partial insulation freezing design together with freezing engineering to coal shaft in special deep alluvium. A reasonable partial insulation plan was proposed. Thickness and displacement of frozen wall can fulfill with the demand of construction in the top and bottom of special deep alluvium.
