摘　　要：为了更科学地做好上庄煤矿瓦斯治理工作,利用钻屑解吸指标法对上庄煤矿9#煤层的原始瓦斯含量进行测定,分析瓦斯含量分布特征,利用线性回归方法研究获得9#煤层瓦斯含量与埋藏深度的关系,并分析了矿井瓦斯涌出量的涌出来源,最后用分源预测法对该矿9#煤层的瓦斯涌出量进行预测,得出矿井瓦斯涌出量为8.41 m3/min。To control gas in Shangzhuang Coal Mine more scientifically,the gas content of 9# coal seam was measured using the method of desorption index of drill, the distribution of gas content in 9# coal seam was also analyzed. Linear regression method was applied to obtain the relationship between gas content and buried depth of 9# coal seam, and the sources of gas emission were analyzed,too. At last, the paper forecasted the gas emission rate of 9# coal seam in Shangzhuang Coal Mine by applying different-source forecast method,the conclusion was drawn that,mine gas emission rate is 8.14 m3/min.
