摘要
根据仙泉煤矿下组煤层地勘瓦斯含量和井下实测瓦斯含量数据,结合煤层瓦斯垂直分带划分标准,确定15号煤层处于瓦斯风化带内。采用分源预测方法对仙泉煤业的采掘工作面进行了瓦斯涌出量预测,预测结果为低瓦斯矿井。
Based on the exploration gas content and the measured methane content of Xianquan Coal Mine,it combined with the theory of gas vertical zoning,it was educated that the No. 15 seam belongs to gas weathered zone. The different - source forecast method was applied to predict the gas emission of the working face in Xianquan Coal Mine. The result shows that the Xianquan Coal Mine belongs to low gas mine.
