矿井煤层气中除包含CH4气体外还往往包含N2、CO2等气体。通过理论分析及实验研究,对于N2在瓦斯压力和瓦斯放散初速度测定时的影响进行了分析,明确了N2对4项单项指标中瓦斯压力及瓦斯放散初速度测定的影响程度。
In addition to CH4 gas, coal mine methane gas often contains N2, CO2 and other gases. Through theoretical analysis and experimental study, the influence of N2 on gas pressure and initial velocity of gas drainage is analyzed, and the effect of N2 on the gas pressure and initial velocity of gas diffusion in four individual indexes is clarified.
