在理论分析煤样粒径对瓦斯放散初速度影响的基础上，实验测定了贵州三对矿井不同粒径下瓦斯放散初速度。对比实验结果表明瓦斯放散初速度受煤样粒径大小影响较大，粒径越小瓦斯放散初速度越大。通过回归分析发现粒径对瓦斯放散初速度指标的影响呈指数函数关系，且有较高的拟合度。
在理論分析煤樣粒徑對瓦斯放散初速度影響的基礎上，實驗測定瞭貴州三對礦井不同粒徑下瓦斯放散初速度。對比實驗結果錶明瓦斯放散初速度受煤樣粒徑大小影響較大，粒徑越小瓦斯放散初速度越大。通過迴歸分析髮現粒徑對瓦斯放散初速度指標的影響呈指數函數關繫，且有較高的擬閤度。

On the basis of theoretical analysis of the impact that coal particle size on initial velocity of gas emission,experiments were done to determine the initial velocity of gas emission in Gui zhou three coal mines. The results showed that the initial velocity of gas emission was influenced a lot from the coal particle size, the initial velocity of gas emission was higher when the coal particle size was smaller. Through the analysis found that the particle size effect oninitial speed of methane diffusion index of exponential function change, and has a higher fitting degree.
