| 摘 要： | 在河北省怀来县后郝窑地区，对地下气体运移变化的影响因素进行了野外模拟实验研究。选择３个试验点，对地下气体的扩散作用，物理化学影响因素及水压效应等进行了模拟实验，主要研究Ｈ２，ＣＯ２气体运移变化机制。实验研究表明，Ｈ２，ＣＯ２气体运移变化机制不尽相同，水压效应对Ｈ２，ＣＯ２等地下气体运移影响相当明显

| Abstract: | Field modeling experiments have been made to study effecting factors for migration changes of underground water gases. Three test sites were chosen in the Houhaoyao area of Huilai county, Hebei Province. The aim of the modeling test is to analyse the diffusion effect of underground gases, the effecting factors of physics and chemics, and the effect of water pressure. The main purpose is to study the mechanism of migration changes of the gases H 2 and CO 2. The results of tests indicate that mechanism of gas migration changes for the gas H 2 is different from that of the gas CO 2. The effect of water pressure on migration of underground gases such as H 2 and CO 2 is rather evident. |
