| 摘 要： | 在理论分析吸附压力对瓦斯放散初速度影响的基础上,实验测定了吸附压力对瓦斯放散初速度的影响。结果表明瓦斯放散初速度受吸附压力影响较大,吸附压力越高瓦斯放散初速度越大,吸附压力越小瓦斯放散初速度越小。实验室测定瓦斯压力时应尽量保持吸附压力为0.1MPa,现场使用该指标时应根据当地的大气压力情况做适当调整。

| Abstract: | On the basis of theoretical analysis of the impact that inflation pressure exerts on initial velocity of gas emission,experiments were done to determine the impact that inflation pressure exerts on initial velocity of gas emission. The results showed that the initial velocity of gas emission was influenced a lot from inflation pressure,the initial velocity of gas emission was higher when inflation pressure was greater,and the smaller the inflation pressure was the lower the initial velocity of gas emission ... |
