基于煤与瓦斯的七个基本参数，应用因子分析方法，得到了反应本煤层抽放难易程度、突出危险性及瓦斯涌出量（不考虑邻近层影响）的三个因子。依据因子得分对开采层瓦斯抽放难易程度及煤与瓦斯突出危险性进行了分类，进而对开采层瓦斯预抽方法进行判断。结果表明，采用因子分析的方法进行开采层瓦斯预抽方法的选择与现场抽放设计基本一致，并且对于传统方法无法分类的情况也给出了合理的分类判断。采用该方法可以较客观、合理的选择开采层瓦斯抽采方法。%Based on the seven coal and gas basic parameters,gets the three factors of coal seam drainage ease,out-burst dangerous and gas emission(don't consider adjacent layer )by using the factor analysis method. Coal seam drainage ease and outburst dangerous are classified according to the factor score,then judge the mining layer gas extraction method. The results show that the factor analysis method is according to the field drainage design,and give out reasonable judgment of the classification which can’t be judged by the traditional method. Using this meth-od can gets a more objective and reasonable choice of mining gas extraction method .
