【摘要】 我国西部地区冻结法凿井是国内外共同关注的重大技术难题,仍处于探索阶段。针对内蒙某矿井冻结法凿井关键技术难题,采用理论计算、冻结岩石室内试验和现场实测等方法进行了研究。获得了我国西部地区白垩系地层冻结壁厚度、冻结温度场参数和人工冻土力学特性等参数确定方法。基本掌握了白垩系地层冻结壁形成特性,为我国西部地区冻结法凿井提供科学指导。更多还原

【Abstract】 In western China,freezing sinking is a major technical problems of common concern at home and abroad and it is still in the exploratory stage.In this paper,we used theoretical calculations,freezing rock indoor test and field measurement to solved the key technical problems of freezing sinking for a mine in Inner Mongolia.The paper received the determination method of freezing wall thickness、freezing temperature field parameters and the parameter of artificial freezing soil mechanical properties.Finally,we grasped the formation characteristics of the freezing wall in cretaceous formation and provided scientific guidance for the freezing sinking in western China.更多还原
