地气动态提取技术的研制及在寻找隐伏矿上的初步试验

地气探测技术是８０年代中期发展起来的寻找隐伏矿的化探新方法。这种方法有可能为当前和今后解决寻找厚层运积物覆盖区的隐伏矿所面临的难题提供一种强有力的手段。但由于其效率低、成本高、操作不方便限制了它的使用。为此，我们开发研制了一种快速动态提取地气技术。通过在某一隐伏矿上的试验，取得了令人满意的效果，并从理论上探讨了地气的迁移机制。为今后开展利用这一技术寻找厚层运积物覆盖区隐伏矿的工作创造了良好的开端。

DYNAMIC COLLECTION OF GEOGAS AND ITS PRELIMINARY APPLICATION IN SEARCH FOR CONCEALED DEPOSITS

Geoges method, a method designed to search for concealed deposits, was developedin mid-1980s. The method may be a powerful means in the prospecting for deeply concealeddeposits. Nevertheless, it has merely a limited application because of its high cost and lowefficiency. Hence, the anchors developed a new rapid method for dynamic collection of geogaswhich has proved to be satisfactory over a buried gold deposit. The possible migration mechanism of geogas is also discussed in this paper. This new technique will enable prospectors to meet the challenge in search for concealed deposits in near future.
