| 摘 要： | 由于瓦斯气的富集，引起富集区域的视电阻率升高。瓦斯气压力越大，其视电阻率就越高。在同一地区，瓦斯气的赋存导致物性异常，特别是视电阻率及密度异常与瓦斯气的富集程度有非常密切的关系，呈现一定的规律。据此，在地面使用超低频地质遥感探测仪，即可探测出地下瓦斯气的富集范围，预测其富集程度。勘探成果可做为煤矿开采时采取抽排瓦斯气措施的依据，做好瓦斯事故的预防工作。

| Abstract: | Owing to gas concentration, caused the rising of apparent resistivity in the concentrated area, the higher the gas pressure, the higher apparent risistivity. In the same area, since the hosting of gas caused anomalous physical properties, especially the apparent resistivity and density anomalies has very close relation to the gas concentration extent and has a regular pattern. Thereafter, to use ULF geological remote sensing device on ground surface can block out gas concentration range and predict its extent. The detecting result can be a foundation to design gas drainage measures during coal mining, and prevent gas accident. |
