摘要
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 contain CH4 , coal bed methane in mine often contains N2, CO2 and other gases. Through theoretical analysis and experimental research, this article analyzes the impact of N2 on the determination of initial speed of gas diffusion and gas pressure, dears the influence degree of N2 on gas pressure and initial speed of gas diffusion determination in four single parameters.
