以陕北地区某矿主井冻结工程为参照原型,将相似理论和模型试验的研究方法应用于饱和砂层冻结壁解冻过程,进而探求解冻过程中的井筒致灾因素,为饱和砂层冻结施工和解冻阶段施工工艺改进提供试验依据。
Based on the freezing project of main shaft in a mine in northern Shaanxi, the research method of similarity theory and model test is applied to thawing process of frozen sand wall in saturated sand layer, and then to explore the hazard factors of wellbore in thawing process to freeze construction of saturated sand layer And thaw stage of the construction process to provide experimental basis for improvement.
