摘要
以小纪汗煤矿小苏计井筒检查孔为研究对象,在安徽理工大学冻土实验室内进行试验,根据冻土的单轴抗压强度试验、单轴蠕变试验及其数据分析得到冻土本构关系曲线以及蠕变曲线规律,这对陕北地区矿井井筒的冻结法的设计和施工具有指导意义。
Taking Xiaosuji shaft inspection hole of Xiaojihan coal mine as the research object, the test carried out in the frozen soil laboratory of anhui university of science and technology, according to uniaxial compressive strength test and uniaxial creep test of frozen soil and data analysis get frozen soil constitutive relation curve and creep curves law, has guiding significance for design and construction of freezing method of the mine shaft in shanbei region.
