摘要
针对保德煤矿瓦斯涌出及瓦斯抽采情况,介绍了8号煤层五盘区瓦斯抽采工艺和抽采钻孔布置,计算了抽采管径和抽采管路阻力,并通过计算抽采泵标况流量,抽采泵工况压力和工况流量进行了抽采泵的选型,通过合理的选型保证瓦斯抽采安全,保证煤矿安全生产。
According to the gas emission and drainage situation in Baode Coal Mine, the gas drainage technology and drainage borehole layout of No. 5 panel in 8# coal seam were introduced, diameter and resistance of drainage pipeline were calculated, and the drainage pump was selected according to the calculation of standard flow conditions, working condition pressure and flow conditions. Through reasonable pump selection, the safety of gas drainage and coal mine production was ensured.
