煤层及其围岩的自然瓦斯含量数据是计算新建和改建矿井巷道瓦斯涌出量的主要原始资料。瓦斯涌出量预测的精度决定矿井设计中工程计算的可靠性:比如风量、主要通风设备能力、开拓巷道的断面和数量以及矿井其他参数计算等。现代气体分析方法的大量试验及其应用,可使煤层及其围岩的瓦斯成分和含量的测定结果更加精确。在这些气
The natural gas content data of the coal seam and its surrounding rock are the main raw data used to calculate the gas emission from the newly built and converted mine tunnels. The accuracy of gas emission prediction determines the reliability of engineering calculations in mine design: such as wind capacity, primary ventilation capacity, section and number of open roadways, and other parameters of the mine. The extensive testing and application of modern gas analysis methods can make the determination of gas composition and content of coal seam and its surrounding rock more accurate. In these gas
