摘要
平凉安家庄煤矿主副风井拟采用冻结法施工,为了给白垩系地层冻结设计提供参数依据,对安家庄井筒检查孔所取土样进行了人工冻结的单轴抗压强度、三轴剪切强度及土壤热物理性能试验研究,得到了其应力-应变的关系及导热比热及结冰温度等参数,试验结果为平凉地区类似矿井冻结设计、施工提供了基础。
Pingliang Anjiazhuang mine primary and secondary air shaft using freeze construction method, in order to provide the western cretaceous freeze parameters for mine design, for Anjiazhuang soil samples were artificially frozen uniaxial compressive strength, triaxial experimental study on physical strength properties and soil heat, get the stress- strain relationship, thermal conductivity and specific heat of freezing temperature and other parameters, test results similar to mine construction Pingliang area provides the design basis.
