| 摘 要： | 瓦斯事故是煤矿井开采作业面临的第一大灾害，它具有发生突然、动力巨大、伤亡力强、波及面宽等突出特点.瓦斯不均匀地的贮存在煤层中，突出于采动破坏的岩壁段，防止煤矿瓦斯事故是一个典型的地学问题.通过测量岩体物性差异预测瓦斯动力赋存的地质条件，通过测定物性差异体的三维空间位置可确定采矿作业的安全岩体隔离厚度，等等.近十年来地球物理探测技术为防止煤矿瓦斯事故发生发挥着关键作用.

| Abstract: | The gas accident is the first major calamity that the colliery exploiting in China, it usually took place very suddenly and tremendouspowerly, and cause extensive injuries and deaths. Gas even store in coal seam, and outstanding on rock wall piece which is destroyed by mining,somining, so it is a typical geological science question to prevent the gas accident of the colliery from occurring. By means of measuring the difference in physical characteristic of rock body we could predict the geological condition that the gas power composes in, By means of measuring the position in three-dimensional space we could determines the security thickness of the rock body with which the mining is protected, and so on . The technology of geophysical survey play a key role in preventing gas accident from occurring in the colliery in the past ten years. |
