摘　　要：鹿台山煤业2号煤层即将采完,15号煤层作为接替煤层开发。现选用分源预测法对鹿台山煤业15号煤层的瓦斯涌出量进行预测,得出15号煤层瓦斯含量梯度为(1.52m^(3)/t)/100m;根据判定规则,确定15号煤层瓦斯风化带高度为301.11m,宽度为2150.79m;最后采用分源预测法对15号煤层的瓦斯涌出量进行预测,并分析矿井瓦斯涌出组成。研究结果显示,煤层在达产状态下,矿井的最大绝对瓦斯涌出量为42.39m^(3)/min,最大相对瓦斯涌出量为33.58m^(3)/t,确定鹿台山煤业属高瓦斯矿井。No.2 coal seam of Lutaishan coal mine is about to be mined out,and No.15 coal seam is de-veloped as a replacement coal mine.The source prediction method is used to predict the gas emission vol-ume of No.15 Coal Seam in Lutaishan Coal Mine.The gradient of gas content in No.15 Coal Seam is(1.52m^(3)/t)/100 m.According to the determination rules,the height of the gas-weathered zone in No.15 Coal Seam is determined to be 301.11m,with a width of 2150.79m.Finally,the prediction re-sults of gas emission volume in No.15 Coal Seam are obtained by using the source prediction method and the composition of gas emission is analyzed.The research results show that under full production condi-tions,the maximum absolute gas emision from the coal mine is 42.39m^(3)/min,and the maximum relative gas emission is 33.58m^(3)/t,confirming that Lutai Mountain Coal Industry is classified as a high-gassy coal mine.
