The research achievements of geogas prospecting through the mechanisms of geogas prospecting and its applied research in the area of concealed uranium deposits prospecting were analyzed. Geogas prospecting is a new means of deeply concealed deposits exploration that started to develop gradually from the 1980s and is at an initial stage of research in concealed uranium deposits exploration. Furthermore, comments and suggestions were provided for following research work by summarizing the shortcomings and problems of current studies in this paper. A general upward micro-flow of geogas could carry the metal nanoparticles associated with ore body underground to the surface of earth to come into being anomaly halos of elements contents above the ore body, and with these anomaly halos, the relevant information of deeply concealed uranium deposits (or other classes of metal ore bodies) would be reflected. The depth that geogas measurement could achieve for prospecting concealed deposits under the covering layers is up to a thousand meter. Geogas prospecting can be used for investigating in small scales, surveying generally and in detail in big scales and locating the ore bodies. At the present stage, there are three primary under-mentioned problems in the studies of geogas prospecting: ①On the one hand, the researches of how mediums (covering layer) would affect the migration process of geogas are far from enough. On the other hand, appropriate mathematical theory models have not been set up yet. ②In China, there are currently few accurate and practical physical models for geogas prospecting to carry out controllable and repetitive series experiments as well as theoretical studies. It is essential that an appropriate physical model should be established timely in order to provide an experimental platform and a kind of technical assistance for the mechanism study of geogas prospecting. ③To achieve the aim of popularizing the geogas prospecting in the uranium exploration area, the research of trapping solution and sampling and measuring methods should be further developed and the methods of rapid geogas in-site measuring which are suitable for various geologic structures of uranium deposits should be made reasonably to cater to the need of rapid and accurate field measurement.
