摘　　要：煤层瓦斯涌出量的预测对于煤矿的安全生产十分重要。鉴于上孔煤业3号煤层无可靠的瓦斯实测数据,采用了相邻的西冯街煤业瓦斯含量数据进行相似预测。经过预测,Ⅲ一盘区的最大瓦斯含量为5.2m^(3)/t。在3号煤层Ⅲ一盘区产量为0.6 Mt/a时,矿井相对瓦斯涌出量为6.03 m^(3)/t,矿井绝对瓦斯涌出量为9.62 m^(3)/min。考虑到煤层瓦斯涌出量是根据相邻煤矿的瓦斯数据确定的,在后期掘进过程中,应该对瓦斯涌出数据进行相应的修正。The prediction of coal seam gas emission is very important for the safety production of coal mine.In view of the lack of reliable gas measurement data in No.3 coal seam of Shangkong Coal Industry,the gas content data of adjacent Xifeng Street Coal Industry were used for similar prediction.It is predicted that the maximum gas content in Ⅲ area is 5.2 m^(3)/t.When the output of No.3 coal seam Ⅲ is 0.6 Mt/a,the relative gas emission of the mine is 6.03 m^(3)/t,and the absolute gas emission of the mine is 9.62 m^(3)/min.Considering that the amount of coal seam gas emission is determined according to the gas data of adjacent coal mines,the gas emission data should be corrected accordingly in the later excavation process.
