摘要
煤矿安全生产的一个重大问题就是矿井瓦斯,瓦斯涌出量的准确预测是煤矿通风系统优化及制定合理瓦斯防治措施的前提条件,禹州市富山煤矿矿井瓦斯随着煤层埋藏深度的增加,瓦斯涌出量将会增大,采区正常生产期间为1个回采工作面、2个煤巷掘进工作面,因此,计算得出生产采区相对瓦斯涌出量为4.43m3/t,绝对瓦斯涌出量为2.77m3/min。
Mine gas problems have been restricting an important factor of safety in production of coal prediction of gas emission is the necessary link of mine ventilation management and prevention and control sonable gas in Toyama coal mine, Yuzhou mine gas, with the increase of buried depth of coal seams, gas enterprises, the measures of rea- gushing volume will increase during normal production, mining 1 mining work surface, 2 coal roadway driving face, therefore, the calculated production mining area of relative gas emission rate is 4.43m^3/t, the absolute quantity of gas emission in 2.77m^3/min.
