| 摘 要： | 在理论分析煤的挥发分与瓦斯放散初速度存在联系的基础上,实验测定了不同挥发分煤的瓦斯放散初速度。结果表明煤的挥发分与瓦斯放散初速度确实存在联系。煤的挥发分越低,即煤的变质程度越高,煤的放散初速度越大。

| Abstract: | On the basis of theoretical analysis of the relation between coal's volatility and the initial speed of methane emission,experiments were done to determine the initial speed of methane emission on different levels of volatility.The results showed that there is relation between coal's volatility and the initial speed of methane emission.The lower volatility was,namely the higher the degree of metamorphism was,the bigger the initial speed of methane emission was. |

| Keywords: | initial speed of methane emission volatility degree of metamorphism |
