| 摘 要： | 通过理论分析及在同一试验条件下,对不同温度下的煤样进行瓦斯放散初速度实验研究,得出了瓦斯放散初速度和温度差值存在着二次项关系,且温度越高瓦斯放散初速度越小。指出了瓦斯放散初速度测定必须在恒定温度下进行,对准确进行突出危险性鉴定有着十分重要的意义。

| Abstract: | In this paper,a quadratic relationship between the initial speed of methane emission and the temperature difference was obtained by theoretical analysis as well as experimental research on initial speed of methane emission of coal sample at various temperatures under the same experimental condition.The higher the shear temperature was,the lower the initial speed of methane emission would be.It was also found that initial speed of methane emission must be conducted under the constant temperature which had im... |
