油页岩原位高温开采，需要在矿区周边建立地下冷冻墙以阻止地下水的流入，防止油气的泄漏。油页岩的高温开采区与地下冷冻墙的冷冻区之间的缓冲距离影响油岩页的开采效果及地下冷冻墙的制冷效果，也影响整个工程的施工成本及运行费用。采用理论计算、数值模拟分析的方法，以最低成本为目标，对合理的缓冲距离进行了详细计算与分析，确定出了合理的缓冲距离，为油页岩高温开采地下冷冻墙的设计提供了理论指导。

For oil shale situ high-temperature mining, underground frozen wall should be constructed to prevent underground water flowing into the mining area and the leakage of oil and gas.The buffer zone between the high-temperature mining area and the freezing zone of underground frozen wall not only affects oil shale mining and frozen wall cooling effects but also af-fects the entire project construction and operating costs.By theoretical calculation method and numerical simulation, with the lowest cost as the goal, the detailed calculation and analysis are made and the rational buffer distance is determined, which could be the theoretical guidance to underground frozen wall design for oil shale in situ high-temperature mining.
